ATV Helmets: The Most Important Accessory

ATVs have recently fast caught on among the youth. It is become a symbol of freedom,excitement and liberation for them. Their ATV means a lot to them. It is more than just a machine that carries you from one place to another. A lot of personal emotion is invested in that. Therefore, it is always right that you give your ATV its due so that it can give you the maximum fun that you desire.


Embellishments to your ATV are always a good idea. It gives a sense that you have personally taken a lot of care to improve its functioning. You can always accessorize ATVs using a wide range of fancy gadgets and gizmos that are easily available. Here are a few that you may consider. We have listed them according to utility though you may want to re prioritize the list. Feel free, because it is your very own baby!


Storage Box: as the name suggests a storage box will help you store anything that you wish to carry with you while riding or camping. It has proper lids and covers that will help keep your things safe and dry.


Hoods and Shields: you want to provide your personal ATV with as much protection as you can from smoke, dust, rust, water, etc. A variety of grills, shields, goods, covers are available in the markets. Invest in one of those to save your ATV from getting unnecessarily damaged.


Pedals: after you have got the more utilitarian accessories in place and you still want to embellish you ATV further you might want to try out pedals in a variety of designs and colors. They can be easily purchased off the internet.


Handles: just like pedals, handles are also easily searchable and purchasable off the internet. It might be a very good idea to add you personal touch by adding a little spunk to your ATV by investing in funky looking and fancy handles. You will again have a wide
range of designs to choose from.


Front Box and Cargo Bags: now is the time to invest in more storage accessories. You may not get a desirable storage box with your ATV and you might consider changing it. Invest in a storage box and cargo bag that meets your specifications as far as design and size are concerned.


Bottle Holder: to make you ride comfortable and to enable you to take a sip of drink while riding, a bottle holder at a convenient place is an excellent investment.

Using Courtesy While Driving An ATV

ATVs have been immensely popular since they were first introduced. and from the very
beginning, those who ride ATVs have had to deal with many concerns regarding their behavior. Many of these are concerned with safety on the trail, while others are about respecting private property. Too many drivers simply drive wherever they please, with complete disregard for the laws prohibiting ATV use in many areas. As with any other motorized vehicle, there are many laws and rules governing ATV use.


The first rule, and some would argue the most important, is to always be on the lookout for others on the same trail. It is the responsibility of every single person on a trail to be aware of their surroundings at all times, and to be on the lookout for both other ATVs and people on foot on the trails. Being aware that someone is there is the critical first step in avoiding an accident.


Since most other vehicle traffic in the US drives on the right hand side of the road, that
convention has transferred over onto the trails. You should always drive on the right hand side, since that is where others will be expecting you to be. If you wish to pass someone, be sure they are aware of you and that you wish to pass. Be sure and wait for an OK before you pass.


Horses always have the right-of way. If you see a horse and rider crossing in front of you, stop and give them the trail. After they have finished crossing, you may continue on. If you are approaching a horse and rider on the trail you are using, be sure first that the rider is aware of you. Signal that you are going to pass, and wait for the OK. Be sure and give the horse as much room as you possibly can. The loud noise and strong smells of an ATV can easily spook a horse, which is dangerous for everyone involved. If the horse starts acting nervous or agitated, shut down your engine and talk to the rider about what to do. Usually, you will simply need to let the horse and rider get some distance between you before you continue on.


It is unfortunate that the majority of safe, responsible, and courteous riders have had their reputation tarnished by a handful of reckless yahoos. It is a fact of life that people are far more likely to remember the obnoxious ATV rider that churned up their field than all the ones that are respectful and stay off their property. The image of the drunken redneck raising hell in the middle of the night on an ATV is unfortunately an all-too common occurrence, especially when drinking or drugs get in the mix. Never drive an ATV while under the influence of alcohol or drugs! Most fatal accidents happen that way.


Even if you are riding on an ATV designated trail, odds are at some point you will encounter someone who isn't using the trail for ATV riding. Be aware of your surroundings, and show any people you meet on the trails the same courtesy you would like to receive. Follow these simple guidelines, and you will have a safe and enjoyable riding experience. Be safe, and have fun!

Tips For Youth ATV Safety

ATVs can be a great way to spend time with your child. If you both take the proper precautions, it can be safe as well. Not approaching ATVs from a safety first viewpoint leads to hundreds of injuries, both adult and child, every year.


ATVs are powerful pieces of machinery and should be approached as such. They can be hard
for an adult to handle at times, much less a child. But children are perfectly capable of handling an ATV as long as some basic principles are followed.


Don't put you child on a ATV that is too large for them. This sounds like common sense, but you would be amazed at how many children are seen on ATVs that would be large for an adult. A light ATV, or in the case of smaller children, a child's ATV are ideal for your kids. Remember though, an ATV is not a toy, and make absolutely sure that your child understands that as well. Treating an ATV like a toy is the surest way in the world to get injured, wreck your ATV, or both.


Before your child ever gets onto an ATV, you both should attend an ATV safety course. There they will learn the basics of ATV operation and what not to do. Then, you should spend some time hands-on teaching your child the basics of ATVs, such as acceleration, braking, turning, and the like.


Always wear safety gear. This goes for both you and your child. Helmets and protective eye
wear are a must, as well as protective clothing like gloves, jackets, and pants. These should be made of something durable, as they will be subjected to a lot of abuse. Do not wear baggy clothing, as it can get caught on either the terrain (such as a tree) or on moving parts on the ATV.


Never let your children ride unsupervised. Do not allow them to ride near roads, train tracks, or on paved surfaces. Riding near cars is dangerous and illegal in most places, and because ATVs are designed to be used off-road they can easily spin out of control on smooth surfaces like roads and concrete. Train tracks, in addition to the danger posed by trains, can cause an ATV to become stuck or flip over.

Know what your child can handle, and don't take them riding in places that are too difficult for them. Most accidents happen because of excessive speed or tackling terrain the wrong way. This bears repeating: watch that speed!


If these simple safety guidelines are followed, you and you child can both look forward to many years of family fun, riding ATVs in the great outdoors. Most of these tips are pretty common sense, and apply to the adults as much as the children. Remember, it's no fun for anyone if either of you get injured out there. Keep it safe, and have fun!

Operating An ATV Safely

While you ATV can be a lot of fun, it is a high powered and heavy piece of machinery. And like all such, an ATV can be dangerous if you are not careful. ATV accidents cause thousands of injuries and sometimes deaths every year. Due to their nature and the kinds of terrain you will negotiate in an ATV, it is not hard to see how an ATV could be dangerous. Here are some general safety tips you should follow to help keep you and your family safe while enjoying the fun of riding an ATV.


Take an ATV safety class. These are usually fairly short and inexpensive. Everyone in the
household who will be riding should attend a safety class as well. Try to get in a class that will actually go out on the trails for some hands-on experience.


There is no substitute for experience. When you are first learning to ride your ATV, you should ALWAYS be riding with a more experienced rider. And that doesn't mean your older brother who started 3 days before you, either. Go riding with someone who has been doing it for some time, and knows how to handle the different terrains you may be crossing. The best way to learn how to navigate a tricky area is to be able to watch someone else who can do it first, and whocan explain what they are doing and why.


No matter how experienced a rider you may become, you will take some falls. Wear clothing
that will protect you when it happens. Always wear a helmet, and goggles or other eye
protection as well, especially if you are going to be going through mud. You will be amazed at how much actually makes it to your face! You should wear pants and a jacket that are thick and durable. You will be whipping through underbrush at relatively high speeds, so protecting yourself from cuts and abrasions is a must. Many injuries each year could have been avoided if the rider had just been wearing sensible clothing, a helmet, and protective eye wear.


Don't start off with the biggest, most powerful ATV you can buy for your first. ATVs can be hard to handle, especially in the difficult terrain where you need to be able to handle it the best. A larger ATV is far more difficult to control than a smaller one. Start with a smaller ATV, and only once you are very comfortable riding that one should you think about getting a bigger ATV.


And last, but not least, use your common sense. Don't try to tackle a climb you honestly don't think you can handle yet. Don't drive recklessly or while drinking. If you are riding at night, take it easier than you would during the day.


If you follow these simple, common-sense guidelines, you should be able to enjoy many years of fun, safe, and injury-free riding

The Great Debate: Two Stroke vs. Four

While the debate over which engine is better, the two-stroke or the four-stroke, is as hotly contested as ever, it may become a moot point in a few years as legislators push to completely end the production of new two-stroke ATVs. So if you are considering buying a new two-stroke, there may not be much time left for you to make your purchase.


Basically the difference between a two-stroke and a four-stroke is that a two-stroke fires once per cylinder per revolution of the cam, where a four-stroke fires once per cylinder every two revolutions of the cam. Without taking anything else into account, a two-stroke will fire twice as often as a four-stroke, producing much more power with the same displacement. Sure sounds like a two-stroke is a no-brainer, eh? Not so fast. There are several drawbacks to the two-stroke design and performance of a two-stroke.


The gasoline in a two-stroke must have oil added to it for proper lubrication and heat dissipation. Because this oil is in the combustion chamber, a two-stroke produces a lot of smoke, which is the main reason for the impending ban on new two-stroke ATVs.


A side effect of all the power that a two-stroke produces is that the engine must be periodically rebuilt. These maintenance rebuilds are not extremely complicated or expensive, but if not performed will lead to a costly full engine rebuild.


For many ATV riders, this constant maintenance is an acceptable tradeoff for the extra power and performance they get from a two-stroke. But this power is only available at nearly wide- open, since the power band is in the extremely high end of the engines RPM range. This is fine, as long as you can keep it there. But often, having to shift or back off causes you to lose that power advantage. Two-strokes are widely used in racing ATV applications, since the experienced rider can use that amazing power to quickly accelerate out of corners and into jumps.


Four-strokes, on the other hand, require much less maintenance than a two-stroke. Spark plug and oil changes are needed on a regular basis, but the frequent rebuilds of a two-stroke are not. If an engine rebuild is necessary, a four-stroke is quite a bit more expensive to rebuild than a two-stroke.



There is no need to mix oil into your gasoline for the four-stroke, so it produces a lot less smoke than a two-stroke does.

As far as performance goes, the four-stroke does lack the sheer power of a two-stroke at its peak, but a four-stroke's power is available through a much wider RPM range than the two-stroke. There is no need to run at wide-open all the time, and leads to a much more leisurely and quieter riding experience. The low-end torque of a four-stroke is much handier when climbing difficult terrain, negotiating mud, or hauling heavy loads than a two-stroke's extreme high-RPM power. In fact, a four-stroke can get out of a full stop in mud, where a two-stroke will usually be completely stuck. And a four-stroke ATV often has a higher top speed than a two-stroke, but will take longer to get there.


In general, four-strokes are better used in recreational ATV riding, hauling, difficult terrain, and such. A two-stroke, on the other hand, will tend to be better suited for racing and light sport ATVs.

How To Conquer The Mud With Your ATV

At some point in your time riding an ATV you will most likely have to get through some mud. Mud can be a challenge to get through, even if you have some experience riding your ATV.


Some ATVs are better designed than others for getting through mud holes. Four wheel drive is obviously going to be a lot better for powering through mud holes than a two wheel drive system. But a lot of the basic technique remains the same no matter what kind of ATV you are driving.


The first thing you should realize is that if you ever stop moving in a mud hole, you are most likely going to become stuck. Approach with some speed, but be careful. Going too fast can cause other problems, like the driver being thrown off the ATV as you suddenly decelerate when hitting the mud. Approaching too slow, on the other hand, often means getting bogged down and stuck.


If possible, you may wish to try and keep one drive wheel on solid terrain to provide traction. This may not always be possible, and you should be careful if you suspect that the mud hole may be deep. Having one side sinking into deep mud with the other on solid ground can cause your ATV to roll.


Some experienced riders may tell you that you should stand on your pegs when entering a mud hole so that you can better respond to any unevenness in the terrain. Again, be careful, as the sudden deceleration may throw you if you are not prepared for it. Be sure of your balance before attempting to ride through a mud hole standing on your pegs.


The most common mistake the beginner makes is to mash hard on the throttle when losing
traction in a mud hole. If your tires are spinning and throwing mud everywhere, they aren't gripping anything or moving you forward. A tire that is spinning slower will be able to grip where a wildly spinning tire may not. This goes double for times you stop in the middle of a mud hole. Take it easy on the throttle, or you will just dig yourself into a hole.


Weight distribution can mean the difference between getting through the mud and getting stuck. You should try and keep as much of your weight as possible over the rear wheels on a two wheel drive ATV. A four wheel drive won't be as sensitive to front-rear weight changes as a two wheel drive, although you should try to avoid digging the front of your ATV down lower than the rear in the mud. Rocking from side to side can help both types get through the mud patch.


A four wheel drive will make short work of most mud pits that can give a two wheel drive real problems, but it is not invincible. If you get in a mud pit that is too deep, you risk pulling mud into your engine intake, which kills it right quick. A snorkel kit and exhaust extensions can allow your ATV to keep running with the engine completely under the mud.


No matter what ATV you are driving, remember that you may only have one shot at getting
through a mud hole without a tow. Familiarity with the trails you are riding on is a big plus, and remember you should always be riding with another experienced rider. Having a buddy on another ATV can mean the difference between a quick pull out of a mud pit, and walking back to your vehicle.

Discovering The Thrills Of An ATV

Since they were first introduced over 40 years ago, ATVs have become more and more popular, with thousands of people taking up the hobby every year in the US alone. Why are they so popular? Well, ATVs are just one heckuva lot of fun to ride. Many people enjoy ATV riding as a way to get out and have fun with the whole family. Others enjoy being able to get far away from everyone else and just enjoy nature whenever they feel like it. But as with all vehicles, there are some things you should know before you hop onto your first ATV.


Your first few times out, you should always be with someone who has experience riding ATVs. Consider taking an ATV riding class where the instructor will take the class out onto the trails for some hands-on in a safe environment. Try it out before you buy! You may discover that you don't care for riding an ATV after all. Don't immediately jump on or buy the biggest, worst machine you can find. Much like motorcycles, you should start with something smaller, in the 440-600cc range. You don't want a machine that can get away from you on a moments notice as your first ATV.


Again, much the same as with motorcycles, if you're a true beginner you should get a used ATV for your first. This is so when you damage it you won't be out so much cash, and you don't want to buy a brand new ATV only to find out you like this other model so much better!


Again, taking a safety course is highly recommended. This will let you get some hands-on in a relatively safe environment with people who know what they are doing and can tell you if you are doing something dangerously or wrongly.


Always read your owners manual thoroughly before even starting your new ATV. There is tons
of useful information about your ATV, how it performs, and how to handle it in these manuals. If you bought a used machine and it doesn't have its owner's manual, you can usually get a replacement from any dealer that sells that brand of ATV. Just write down the serial number and go ask them for a replacement copy.


After all this, you are ready to go out on your own. Even experienced riders usually go out with someone else. At some point, you probably will roll your ATV, and they can be extremely heavy and hard to get back upright by yourself, even if you are not injured. But if you are careful and follow the safety lessons and the owners manual on what slopes can be safely handled, that shouldn't happen. Always better safe than injured alone in the middle of the woods, though.


Just follow these easy guidelines, use some common sense, and don't get too crazy, and you
should be fine and enjoying the thrill of riding an ATV!

Choices To Make For Your First ATV

Types of ATVs


ATVs can be broken into to very general categories: sport and utility. Utility ATVs will have racks for carrying things mounted front and/or back and will be geared a little lower for better pulling power. A sport model will usually lack the racks, and will often be lighter and faster as well. If you are a hunter, or just need to haul a lot of stuff in and out of the woods, the utility model is for you. If you are mainly interested in tolling through the woods or any kind of racing, a sports model will be your best bet. Don't forget, you can get racks on sports models as well most of the time, or take a rack off of a utility model of you don't need it.

Engine Designs


There are two engines available for the most part: the 2-stroke and the 4-stroke. A 2-stroke requires oil mixed with the fuel, since they are self-lubricating, and generally run louder and at higher RPM than a four stroke. The 4-stroke works much like a car engine, with an oil reservoir, and are generally much quieter than their 2-stroke counterparts.


Transmissions


A term that often trips up newcomers is the automatic clutch. An automatic clutch is NOT an automatic transmission. You still have to manually change gears when needed, but you don't have to worry with the clutch while doing so. 2x2 or 4x4 is also a consideration. A purely offroad ATV will be best served by 4 wheel drive, while a racing ATV will gain from the weight savings of a 2 wheel drive. And don't neglect the drive train. An enclosed solid driveshaft will be much more robust than a chain or belt drive, while being heavier.


Above all, consider what you plan on doing with the ATV before you make the purchase. There are large differences among ATVs designed for different duty types, so be sure you choose one that matches what you are going to use it for. Choosing the wrong ATV can make for an unhappy owner, and thats not good for anyone involved. Choose well, and you will get years of enjoyment from your ATV.

ATV for Beginners
An Introduction to ATVs


Since the first ATV was introduced a few decades ago, the ATV has been extremely popular. An ATV is very exciting to ride, and the sense of freedom and exhilaration a rider feels is a major draw for repeat riders. ATVs are a sport that the entire family can enjoy. But more people are hurt every year riding ATVs than nearly any other recreational activity. If you are interested in taking part in this exciting activity, there are a few things you should know before you get started.


Don't Go it Alone


The first thing you should do is hit the back trails along with someone who knows what they are doing. This could be a friend, an ATV safety instructor, or a relative that has been riding for a while. the important thing is that you actually get to ride an ATV so you can see if you really want to get one and to get a feel for the machine.


Purchasing your first ATV


Once you are decided, it is time to go pick your vehicle. There are guidelines of ages and
weights VS the class of ATVs that are recommended for operation. Use common sense here,
don't go buy your 85 pound son the biggest monster of an ATV you can get a hold of.


It is recommended that your first ATV be a used one. As a beginner, there will most likely be damage done to your first ATV while you learn the ins and outs, and learning the best maintenance practices are best done on an older ATV. Even if you are very careful, you still may wish to stick with an older machine until you are familiar enough with ATVs in general to decide what new machines fit you best. Everyone you talk to will have a different opinion, and you don't want to buy an expensive ATV only to find out that "that model" is better, according to someone else. It can be very easy to get caught up in the "grass is greener" syndrome, so stick with a cheaper older ATV until you are SURE which new ATV you want is always a good idea.

Learning the Ropes


After you purchase your first ATV, it is HIGHLY recommended that you take an ATV safety and instruction course. These courses are usually between 2 and 4 weeks, broken up into 2-3 hour sessions once a week. Try and get into a course where the instructor will actually take you out onto the trails at some point. A sport as active as ATVs can't be taught entirely in a classroom.


Secondly, you should read the owner's manual. There is a ton of useful information, procedures, and explanations of parts and terminology in the manual. If you bought a used ATV, and it didn't come with an owner's manual, you can usually get one from an ATV dealer that carries your make of ATV. Just get the serial number off your ATV, and the dealer should be able to get the owner's manual for you.


Last, but not least, get out there and ride! There is truly no other way to learn how (and how not) to drive an ATV. Make sure you get permission from the property owner if you will be riding on private property. Be careful, especially at first. Start off slowly, and ride safely. Always ride with more experienced people, but in the beginning, don't try to emulate the "fancier" moves they may be capable of. Learn how to ride safely first! And never ever ride alone. This cannot be stressed enough. Someday, you WILL roll your ATV. And unless you are a bodybuilder, you will probably need help getting your ATV upright again. This goes double if you get injured.


Rules to Play By


By following these simple guidelines, you will be out and having a blast with this exciting sport in no time. As with most things in life, you cannot jump in and expect to be an expert. Always ride with someone more experienced than you, take the time to complete the safety courses, and read your manual. Get out there as often as you feel like and tear up those trails! Practicing driving your ATV IS the fun of driving an ATV. Following these rules will help insure that you enjoy many years of enjoyment and fun on your ATV

ATV Helmets: How Good Is Yours?

Nowadays there are absolutely conflicting views on helmets. Some are of the belief that helmets save lives, but there are others who are of the opinion that helmets create neck injuries and also aggravate the condition of the rider in case of an accident. The question here arises, that what you should believe to be true.


This indecision can be wiped off only with the help of facts that we have gathered. Helmets are made to protect our head. And there is no undermining the importance of our head. It contains our sense organs and any injury can lead us to be blind, deaf, mute or physically deformed. Most importantly, our head contains our brain which controls all the involuntary functions of the body such as the blinking of eyelids, beating of the heart and even breathing. In order to be sure that the helmet that we choose is of a good quality and will be able to protect us in times of collision and accidents, it is important to choose a helmet not on the basis of price and brand but on the basis of a real test


Helmets must pass a very dogmatic test, it involves a real collision. After this, augmentation in its construction can be done. The outer shell of the helmet should be such that it dose not get scraped or easily penetrated. Also it must provide enough support so that it can even out the feet of collision and save the brain from any damage.


Opposite to the general belief that a pricey helmet is a safer one, the actual truth is that price has no relation to the safety provided by a helmet. It is important to keep in mind that price is not a standard that can be used to measure the effectiveness of a helmet. Price does not speak anything. On the other hand ratings can be said to be a standard. If the helmet has passed the most difficult of tests then it is bound to have a good customer rating. But while doing it don’t forget to put o your helmet, as safe comes first


Helmet is meant for safety first, so while buying a helmet what you should look at is its features and not its price and brand. So the next time the weather is nice and the sun is shining an inviting, do not sit back, take out your motorcycle from the garage and go out in the open.

ATV Helmets: Protection For Young Riders

When you are educating your kids about ATVs the first thing that you must teach your children is safety. Tell them the importance of ATV helmets because it can even save life in some dangerous situations. Your kids will of course argue that they do not need ATV helmets, as they will promise to be very careful. But it is your duty to explain to them that precautions are necessary and very useful. Also most of the states have a rule that it is a must to be wearing ATV helmets.


You have to make sure that your kids fully understand that ATV helmets can actually save life. You have to convince them that although they might be extremely careful while riding the bike, still every day is not a lucky day. There might be a chance that there is a misjudgment on thepart of the other person or just a sheer slip or a skid. Thus put in to heads of your kids that ATV helmets are a must so that they are safe and sound.


Don’t be a preacher, practice what you preach. If you are yourself an ATV enthusiast, then
make sure that you yourself always wear a helmet while using it. Make sure that your kids never ever see you riding without your helmet on. This will create a good example in front of your kids.


One common excuse that youths give for not wearing an ATV helmet, is the fact that it makes their hair look flat you will constantly hear young ones say that they look good on an ATV helmet, but they look unimpressive once they have taken it off. Yes it is true, but just make them realize that they would not be able to impress any one if any thing were to happen to them either.


One thing that you can do is to let the children choose their ATV helmets themselves. This way chances are less that they will find the helmet not cool. There are also high chances that they will wear it, with or without flat hair.


It is important to choose the right helmet. As helmet is the single most important ting that can save your life. It is important that your kids realize tat wearing a helmet is a wise thing to do and not something that makes them look not cool .Once they realize this fact even you can e at peace when your kids are out riding.

From Wikipedia, the free encyclopedia

d = run
?h = rise
l = slope length
? = angle of inclination

This article is for the grade of a topographic feature or constructed element, for other uses see: Slope (disambiguation)

The grade (also called slope, incline, gradient, pitch or rise) of a physical feature, topographic landform or constructed element, refers to the amount of inclination of that surface to the horizontal. It is a special case of the gradient in calculus where zero indicates gravitational level. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which run is the horizontal distance and rise is the vertical distance.

Grade or slope is applied to measuring existing physical features (such as canyon and hillsides, stream and river banks and beds), or in designing and engineering new elements for construction (such as roads, landscape and garden grading, roof pitches, railroads, aqueducts, and pedestrian-handicapped-bicycle circulation

Expression nomenclature

Illustration of grades in percent and angles in degrees

There are several systems for expressing slope:

1. as an angle of inclination to the horizontal. (This is the angle ? opposite the "rise" side of a triangle with a right angle between vertical rise and horizontal run.)
2. as a percentage, the formula for which is which could also be expressed as the tangent of the angle of inclination times 100. In the U.S., this percentage "grade" is the most commonly used unit for communicating slopes in transportation (streets, roads, highways and rail tracks), surveying, construction, and civil engineering.
3. as a per mille figure, the formula for which is which could also be expressed as the tangent of the angle of inclination times 1000. This is commonly used in Europe to denote the incline of a railway.
4. as a ratio of one part rise to so many parts run. For example, a slope that has a rise of 5 feet for every 100 feet of run would have a slope ratio of 1 in 20. (The word "in" is normally used rather than the mathematical ratio notation of "1:20"). This is generally the method used to describe railway grades in Australia and the UK.

Any one of these expressions may be used interchangeably to express the characteristics of a slope. Grade is usually expressed as a percentage, but this may easily be converted to the angle ? from horizontal since that carries the same information.

There is a method in which slope may be expressed when the horizontal run is not known: rise divided by the hypotenuse (the slope length). This is not a usual way to measure slope. This follows the sine function rather than the tangent function and this method diverges from the "rise over run" method as angles start getting larger (see small-angle formula).

Many of the mathematical principles of slope that follow from the definition are applicable in topographic practice. In the UK, for road signs, maps and construction work, the gradient was traditionally expressed as a ratio such as 1 in 12, but signs showing gradient expressed as a percentage are becoming more common.^[1]

In civil engineering applications and physical geography, the slope is calculated along a particular direction of interest which is normally the route of a highway or railway road bed.
