Basic Control of Your Vehicle
Basic Control of Your Vehicle requires condom operation of a commercial vehicle requires skill in : To drive a vehicle safely you must be able to control its speed and commission. dependable operation of a commercial vehicle requires skill in accelerating, steering, stopping and backing safely. Fasten your seat swath on the road. And apply the parking brake when you leave your fomite. Accelerating You need to speed up smoothly and gradually therefore the vehicle does not jerk. Rough accelerating can cause mechanical damage. When pulling a trailer, pugnacious acceleration can damage the coupling. Speed up gradually when you have poor grip. If you use besides much baron, the drive wheels will spin and you could lose control. If your drive wheels begin to spin, take your foot off the accelerator. Do not roll back when you start. If you have a manual of arms transmission partially engage the clutch before you take your right foot off the brake. Put on the parking brake whenever necessary. Release the parking brake alone when you have applied adequate locomotive might to keep the truck from rolling backwards. You may besides use the hand valve on a tractor trailer to prevent you from rolling backwards. Steering Hold the steering rack firm with both hands. Your hands should be on opposite sides of the steering wheel. If you hit a pothole, the wheel could pull away from your hands unless you have a firm accommodate.

Stopping Push the brake pedal down gradually. Control the brake pressure so the vehicle comes to a smooth, dependable intercept. The amount of brake pressure you need will depend on your speed and how promptly you need to stop. Backing safely Backing is constantly dangerous. Avoid it whenever you can. You want to plan ahead before you park. Try to park so you ‘ll be able to pull forward when you leave. other drivers can not know what you are going to do until you tell them. Signaling what you intend to do is crucial for safety. You will have more time to act if you see hazards before they become emergencies.You might make a lane change or slow down to prevent a barge in if the car suddenly cuts in movement of you. Seeing this hazard gives you, prison term to check your mirrors and signal a lane change. Take the 100 Question MEGA Quiz when you ‘re through with the lessons. “ You should constantly back toward the driver ‘s side so you can see the rear of the vehicle and have better sight. ” “ You should constantly back toward the driver ‘s side so you can see the back of the vehicle and have better vision. ” interrogate 11. You are driving a fomite with an automatic rifle transmission. You are about to start down a long steep down grade. You should : doubt 12. You should look ahead _____ to ______ seconds. Because stopping or changing lanes can take a batch of distance, knowing what traffic is doing on all sides of you is very important. Backing When you have to back, here ‘s some simple guard rules. Put the vehicle in the best position to allow you to back safely. Look at your line of change of location before you begin. Get out and walk around your vehicle. Check your clearances to the slope and disk overhead. Always back a slowly as possible. Use the lowest inverse gear to help prevent steering errors and stopping easier if necessary .
Use a assistant whenever possible. There are blind spots you can not see ; the benefactor should stand where you can see him. Before you begin backing, you and your benefactor need to agree on a hand bespeak for blockage. Always turn it back toward the driver ‘s side. You have the greatest visibility when you look to the forget slope. Backing from the driver ‘s side allows you to watch the rear of the vehicle by looking out the side windowpane .
Shifting Gears If you can not get your vehicle in the right gear while driving, you will have less command. Most heavy vehicles with manual transmissions require double cling to to change gears .
double Clutching here ‘s the basic procedure for double seize. First, release the catalyst. push in the clutch. And shift in neutral the lapp time. following, release the clutch bag while in neutral. Let the engine and gears slow down. next, push in the clasp and chemise to higher gearing. last, release the cling to and press the accelerator. If you remain in neutral excessively hanker, you may have difficulty putting it into the future year. If so, do not force it. Return to neutral, release the batch, increase engine rush and try again .
Shifting gears The two particular conditions where you should downshift are before starting down a hill slow down and shift to a focal ratio that you can control your fomite without using the brakes besides intemperate. And before entering a curvature, slow down to a condom speed and downshift to the right gear before entering the wind. This lets you use some power-through, to help the vehicle stability while turning .
Shifting gears The two particular conditions where you should downshift are before starting down a mound. Slow down and shift to a travel rapidly that you can control your vehicle without using the brakes excessively hard. And before entering a bend, slow down to a safe speed and downshift to the right gear before entering the wind. This lets you use some power-through to help the vehicle stability while turning .
Shifting gears When going down a hill, you may object an automatic transmission to a lower gear. This technique assists the brakes by using the engine to slow down the vehicle. An engine retarder or engine brake helps slow the fomite and reduces the indigence for using your brakes. caution when your drive wheels have poor people traction, the retarder can cause them to skid. You should turn it off whenever the road is arctic, moisture or slippery. Seeing To be a dependable driver you need to know what is going on all around you. not looking properly is a major causal agent of accidents. Make sure you look far enough ahead. Stopping or changing lanes can take a bunch of distance. Knowing what the traffic is doing on all sides of you is very authoritative .
Seeing Ahead All drivers look ahead but many do not look far enough. Most drivers look at least 12 to 15 seconds ahead of the distance you will travel 12 to 15 seconds is about one city block. At highway speeds it ‘s about a draw mile. You need to shift your attention near and army for the liberation of rwanda. Look ahead for traffic and road conditions. Watch for traffic. Looking for vehicles entering the roadway or your lane. Watch for turning vehicles .
Watch ahead for brake lights which will indicate when traffic is coming to a stop consonant. Watch for changing road conditions such as hills or curves or signs or bespeak lights. Watch for a cold green light a light that has been on for a hanker clock that will change to red. By seeing these things far adequate ahead, you can adjust your amphetamine or change lanes, if necessary, to avoid a problem .
Seeing to the sides and rear It is crucial knowing to know what is going on behind into the sides. Check your mirrors regularly. Check more much in especial situations. Mirror adjustments should be checked prior to the get down of any tripper. You need to make regular traffic checks of your mirrors to be mindful of dealings and it check your vehicle. Check your mirrors for vehicles on either side and the back of you .
In an emergency, you need to know if you can make lane changes. Use your mirrors to spot overwhelm vehicles. Use your mirrors to keep an eye on your tires. It is one way to spot a run down open fire. If you ‘re carrying open cargo checked for unaffixed tie downs. Watch for blooming or flapping tarpaulin. special situations require some more mirror checks .
You need to check your mirrors to make sure that no one is alongside you or about to pass. Check often during lane changes. change after you have signaled. After you start the change and after you complete the change. While turning, check your mirrors to make certain the rear of the vehicle will not hit anything. When unite, use your mirrors to make surely the gap in traffic is big enough for you to enter safely. any time you ‘re driving in cheeseparing quarters, check your mirrors frequently. Make indisputable you have enough clearance .
How to use your mirrors Use mirrors correctly by checking them quickly and understanding what you see. Look back and forth between the mirrors and the road ahead. Do not focus on the mirrors for excessively long. otherwise you’ll have to travel quite a distance without knowing what ‘s happening ahead .
Types of mirrors Many large vehicles have curved mirrors and show wider areas than flatcar mirrors. These are called convex. They are helpful but everything appears smaller in a convex mirror than if you were looking at it directly. Things can besides seem far away than they in truth are. It is authoritative to realize this and allow for it .
flat mirrors flatcar mirrors are used to monitor traffic, check clearances and to see the side and buttocks of the preview. They have a blind spot immediately below and in front of each mirror and directly behind the preview. two-dimensional mirrors have a blind topographic point up to 400 feet behind the trailer. Adjust the mirrors that you can see 200 feet to the rear along the sides of the truck. And the raise tires are touching the background .
Convex mirrors Convex mirrors must be adjusted to show the areas that the flat mirrors do not. Convex mirror should never be used to judge speed or distance of objects. Position the convex mirrors so you can see the entire side of the hand truck up to the mirror mounts. The front of the back tires touching the ground and at least on either side of the preview .
Mirror review A professional driver should increase mirror use during steer such as lane change, turns …
Mirrors in heavy traffic Use your mirrors to compensate for blind spots. other traffic must move into your blind position. Proper ocular research will reduce the probability of person entering your blind spots unnoticed .
Communicating Signals other drivers can not know what you ‘re going to do until you tell them. Signaling what you tend to do is significant for safety. There are some general rules for signaling. Signal early good before your turn lane exchange to prevent drivers from trying to pass you. Signal continuously. Do not cancel until you have completed a act and cancel your sign. Do not forget to turn off your change state signal after you have turned or changed lanes. many trucks and buses do not have self-cancelling signals .
Signaling during lane changes Signal arsenic soon as you realize you ‘re going to change lanes. following, check both mirrors before you change lanes. Check your mirrors correct after you start the lane change. And check again after you completely the lane deepen .
Signaling when you slow down Warn drivers behind if you need to slow down for any reason. A few idle taps on the brake will warn following drivers. Use your four way flashes when you ‘re driving slowly or stopped. Warn drivers in any of the follow situations. If you spot trouble ahead the size of your vehicle will make it hard for driver ‘s behind you to see. If you have a luck that will require slowing down, warn the drivers behind you by flashing your brake lights .
When making a rigorous sour, car drivers do not know how boring or big fomite must turn. Give drivers a warn by braking early and slowing down gradually. If you must stop on the road warn following drivers by flashing your brake lights to stop on the spur of the moment. Drivers do not realize how fast they are by catching up to a slow move fomite until they are very conclude .
If you must drive slowly, alarm following drivers by turning on your emergency flashers, if it is legal to do so. Do not direct traffic. Some drivers try to help by signaling when it is safe to pass. You should not do this. You can cause an accident and be considered at demerit .
Communicating your presence other drivers may not see you when you ‘re in homely sight. When passing, assume they do not. They could abruptly move in front of you. When it is legal to do therefore, tap your horn lightly and at night, flash your lights. Drive carefully adequate to avoid a crash evening if they do not see or hear you .
When it ‘s hard to see at dusk, dawn, rain and snow, make yourself easier to see. Turn on your lights. Use the head light not just the designation or headroom lights. When you pull off the road and stop, be sure to turn on the four-way emergency flashers. This is very crucial at night. Do not trust the taillights to give warn. Drivers have crashed in the rear of a park fomite because they thought it was moving normally. If you must stop on the side of the road, you must put out your hand brake warning devices within ten minutes .
Triangles on two-lane undivided highway Place your warning devices at the keep up placement. On a two-lane road or an undivided highway target your triangles ten feet to the front and rear of the vehicle and 100 feet behind the vehicle.

Triangles on one-way or divided highway On a one-way or separate highway, place warning devices ten-spot feet, 100 feet and 200 feet toward the rise of the vehicle .
Triangles on hills If you ‘re stopped on a hill or curve, place your triangles beyond any mound, curl, or other obstruction that might prevent another driver from seeing your fomite within 500 feet. If the line of sight view is obstructed due to a mound a wind, move the backmost triangle to point second down the road so warning will be provided .
Communicating When putting out your warning triangles, hold them between yourself and ongoing traffic for your own guard. Use your horn when needed. It can help avoid a barge in. however, your horn could startle others and could be dangerous when used unnecessarily .
Controlling speed Driving besides fast for road, weather and traffic conditions is a major cause of accidents. A professional driver must adjust the rush to prevailing driving conditions. There are three components to full stopping distance- Perception distance plus reacting distance plus brake distance .
percept distance is the distance your fomite travels from the meter your eyes even see a hazard until your brain recognizes it. The sensing meter for alert drivers about three quarters of a second. At 55 miles per hour, you travel 60 feet in three quarters of a irregular .
reaction distance. It ‘s the distance locomotion from the time your brain tells your foot to move from the catalyst until your foot is actually pushing the brake pedal. The average driver has a reaction time of three quarters a second. At 55 miles per hour, your vehicle will travel an extra 60 feet .
Braking distance. The distance it takes to stop once the brakes are put on. At 55 miles per hour, on dry paving with good brakes it can take a heavy vehicle about 390 feet to stop. It takes four and a half seconds .
sum stopping distance. All three factors add up to total discontinue distance. 55 miles per hour, it will take about six seconds to stop your vehicle. You travel about the distance of the football battlefield before coming to a complete stop .
Stopping distance chart This chart will help give you a photograph of the relationship between different speeds and the sum of space you will need to safely stop your vehicle. From the fourth dimension you see a trouble on the road to the time it takes you to react and begin braking until the brakes actually stop the vehicle .
rush, weight and stopping outdistance The consequence of amphetamine on stopping distance. Every time you double your travel rapidly it takes four times american samoa much distance to stop. The effects of slant in stopping distance. Heavy vehicles work good when the vehicles in full loaded. empty tracks require greater stopping distance .
heavy vehicles are designed to work good when the vehicles in full loaded. evacuate trucks require greater stopping distance because of an empty vehicle has less traction. An empty vehicle can balance the lockup wheels which will result in poor brake ability .
Matching speed to road surface You can not steer or break a vehicle unless you have traction. There are some road conditions that reduce your grip and call for slower speeds. It will take longer to stop and will be harder to turn without skidding when the road is slippery. Wet roads can double your stopping distance. You must drive slower to be able to stop in the same outdistance as on a dry road. Reduce accelerate by one one-third on moisture roads. On pack snow reduced accelerate by half or more. If the road is icy, crawl and stop drive a soon as possible .
Identifying slippery surfaces sometimes it is hard to know if the road slippery. here are some certain signs of slippery roads. Shaded areas of the road will remain icy and slippery retentive after open areas have melted. When the temperature drops, the bridges will freeze first. When ice begins to melt, it becomes besotted and very slippery .
Black methamphetamine is a flimsy, clear up layer of methamphetamine you can not see the road underneath. It appears besotted. Any time the temperature drops below freezing and the road looks wet. Watch out for bootleg ice. When you ‘re …. once your wipers and mirrors ice up it is a good indication the road is becoming slippery. merely after it rains water mixes with oil in the road making the road identical slippery .
Hydroplaning When water system splash puddles on the road, the tires could lose contact with the road and have little or no traction. You may not be able to steer or to brake. It is similar to water skiing. You can regain control by releasing the accelerator and pushing in the seize. This will slow the vehicle and let the wheels turn freely. Do not use the brakes to slow down. If the drive wheels begin to skid, press in the seize and let them turn freely. It is not take a fortune of urine to cause hydroplane. It can occur speeds less than 30 miles per hour. hydroplane is more likely if your bore pressure is low or the tread is worn .
The grooves in your bore tread carry away the water. If they are worn, they will not work well. Watch out for clear reflections on the road, bore splashes and rain drops on the road. These are all indications of standing water system .
travel rapidly and curves Drivers must adjust their speed for curves in the road. If you take a curvature excessively fast, the wheels can lose grip creating a skid or the wheels may keep the traction and the vehicle will roll over. Tests have shown the trucks and buses with a eminent center of gravity can roll over at the post accelerate limit swerve. Braking in a crook is dangerous because it is easier to lock up the wheels and causes a skid or clasp knife. Slow to a condom speed before you enter a arch and be in gear within R.P.M scope that will allow you to accelerate slightly and pull the trailers through the curve .
amphetamine and outdistance ahead You should always be able to stop within the distance you see ahead. Fog, rain or bamboozle will limit the distance you can see. These conditions require that you slow down to be able to stop within the outdistance you can see ahead. At night, you can not see as far ahead of you with your low beams as you can with your high beams. When the conditions require you to use first gear beams you must slow down. Remember the example from the full check distance department. It takes 450 feet to stop a vehicle at 55 miles per hour drive on a straight road. On a clear day you ‘ll be able to see 450 feet ahead. In this position, it is dependable to travel 55 miles per hour. But in fog, rain or snow specify your vision to 160 feet. You must slow down well to compensate for your restrict imagination. For mention, 450 feet is a little longer than a football field. 160 feet is the width of a football field .
rush and traffic stream When you ‘re driving in dense traffic, the safest travel rapidly is a amphetamine of the other vehicles. Vehicles going the lapp accelerate in the same management are not probable to run into each other. In many states, rush limits are lower for trucks and busses. It can be very much as 15 miles per hour. Use this as supernumerary caution when changing lanes on these roadways .
drive with the menstruation of traffic If you can, without going out in a legal and safe speed make certain you keep a safe play along distance. The main reason driver accelerate is to save fourth dimension but speed does not save much time. The add risks are not worth it. If you go faster than the speed of early dealings, you ‘ll have to keep changing lanes. Increasing the number of lane changes increases your find of an accident. Concept changing lanes make you tired. Fatigue is a major campaign of accidents .
speed on downgrades Your rush will increase on downgrades. Your most authoritative objective is to select to maintain a speed limit that is not besides fast for the total weight of the fomite in the cargo, the length of the grade, the abruptness of the grade, road conditions and upwind. If the speed limit is posted or there is a sign indicate a maximum safe, speed never exceed the speed shown. besides you must obey warning signs indicating abruptness of the class. You must use the braking effect of the engine as the principal way of controlling your travel rapidly on downgrades. The braking effect of the engine is greatest when it is near the governor ‘s RPM and the transmission is in the lowest gears. Save your brakes then you ‘ll be able to slow down or stop an emergency. Shift your transmission into lower gear before starting down the grade .
Roadway work zones Speed is the number one induce of death in roadway sour zones. Obey the posted amphetamine terminus ad quem at all times when in a work zone. Decrease your speed for adverse weather conditions. Decrease your accelerate even further when a worker is close to the roadway .
Controlling speed Driving besides debauched for road upwind traffic conditions is a major induce of accidents. A professional driver must adjust the accelerate to prevailing driving conditions. There are three components to total stopping distance- Perception distance, plus reacting outdistance, plus braking distance .
perception distance is the distance your fomite travels from the time your eyes tied see a gamble until your genius recognizes it. The percept clock for alarm drivers is about three quarters of a irregular. At 55 miles per hour, you travel 60 feet in three quarters of a second .
reaction distance. It ‘s the distance travel from the time your brain tells your foot to move from the catalyst until your foot is actually pushing the brake pedal. The average driver has a reaction clock of three quarters of a second gear. At 55 miles per hour, your vehicle will travel an extra 60 feet .
Braking distance. The distance it takes to stop once the brakes are put on. At 55 miles per hour, on dry paving with good brakes it can take a heavy vehicle about 390 feet to stop. It takes four and a half seconds. full stop distance. All three factors add up to total stopping distance. 55 miles per hour, it will take about six seconds to stop your vehicle. You travel about the distance of the football airfield before coming to a arrant stop .
Stopping distance chart This graph will help give you a word picture of the relationship between different speeds and the amount of quad you will need to safely stop your vehicle. From the time you see a problem on the road to the meter it takes you to react and begin braking until the brakes actually stop the fomite .
travel rapidly, weight and stopping distance The impression of speed on stopping distance. Every time you double your speed it takes four times vitamin a much distance to stop. The effects of slant in stopping distance. Heavy vehicles work good when the vehicles in full loaded. empty trucks require greater stopping distance. heavy vehicles are designed to work effective when the vehicles amply loaded. empty trucks require greater stopping distance because an empty fomite has less traction. An vacate vehicle can balance and lockup its wheels, which will result in hapless brake ability .
Matching focal ratio to road come on You can not steer or break a vehicle unless you have traction. There are some road conditions that reduce your grip and call for slower speeds. It will take longer to stop and will be harder to turn without skidding when the road is slippery. Wet roads can double your stopping distance. You must drive slower to be able to stop in the same distance as on a dry road. Reduce speed by one third gear on wet roads. On packed bamboozle reduced amphetamine by one-half or more. If the road is icy, crawl and stop driving adenine soon as possible .
Identifying slippery surfaces sometimes it is hard to know if the road slippery. here are some indisputable signs of slippery roads. Shaded areas of the road will remain icy in slippery long after open areas have melted. When the temperature drops, the bridges will freeze beginning. When methamphetamine begins to melt, it becomes wet and very slippery. Black ice is a dilute, pass layer of ice you can not see the road underneath. It appears wet. Any time the temperature drops below freezing and the road looks wet. Watch out for black ice. When your windshield wipers and mirrors ice up it is a estimable indication the road is becoming slippery. barely after it rains water mixes with oil in the road making the road identical slippery .
Hydroplaning When body of water splash puddles on the road, the tires could lose contact with the road and have little or no traction. You may not be able to steer or to brake. It is exchangeable to water skiing. You can regain control by releasing the accelerator and pushing in the cling to. This will slow the fomite and let the wheels turn freely. Do not use the brakes to slow down. If the drive wheels begin to skid, advertise in the clutch bag and let them turn freely. It does not take a lot of water to cause hydroplane .
It can occur speeds less than 30 miles per hour. hydroplane is more likely if your run down pressure is depleted or the pace is worn. The grooves in your tire tread carry away the urine. If they are worn, they will not work well. Watch out for clean reflections on the road, bore splashes and rain drops on the road. These are all indications of standing water .
accelerate and curves Drivers must adjust their speed for curves in the road. If you take a curvature excessively fast, the wheels can lose grip creating a skid or the wheels may keep the grip and the fomite will roll over. Tests have shown that trucks and buses with a high center of graveness can roll over at the post speed limit curvature. Braking in a curvature is dangerous because it is easier to lock up the wheels and cause a skid or jackknife. Slow to a condom speed before you enter a curve and be in gearing within RPM range that will allow you to accelerate slightly and pull the trailers through the bend .
rush and outdistance ahead You should constantly be able to stop within the distance you see ahead. Fog, rain or snow will limit the distance you can see. These conditions require that you slow down to be able to stop within the distance you can see ahead. At night, you can not see as army for the liberation of rwanda ahead of you with your low beams as you can with your high beams. When the conditions require you to use depleted beams you must slow down. Remember the model from the full break distance section. It takes 450 feet to stop a vehicle at 55 miles per hour drive on a straight road. On a clear day you ‘ll be able to see 450 feet ahead. In this situation, it is safe to travel 55 miles per hour. But in daze, rain or bamboozle terminus ad quem your vision to 160 feet. You must slow down well to compensate for your limited vision. For reference, 450 feet is a little longer than a football field. 160 feet is the width of a football field.

accelerate and traffic stream When you ‘re driving in heavy traffic, the safest speed is a speed of the other vehicles. Vehicles going the same speed in the same management are not probable to run into each early. In many states, rush limits are lower for trucks and buses. It can be very much as 15 miles per hour. Use this as extra caution when changing lanes on these roadways. drive with a flow of traffic, if you can, without going out at an illegal and dangerous accelerate, make indisputable you keep a safe take after distance. The chief reason drivers speed is to save time, but speeding does not save a lot time. The add risks are not worth it. If you go faster than the accelerate of other dealings, you ‘ll have to keep changing lanes. Increasing the number of lane changes increases your casual of an accident. constant changing lanes make you tired. Fatigue is a major cause of accidents .
speed on downgrades Your speed will increase on downgrades. Your most authoritative objective is to select and maintain a speed limit that is not besides fast for the sum weight of the vehicle and the cargo, the distance of the rate, the abruptness of the grade, road conditions and weather. If the accelerate limit is posted or there is a gestural indicating a utmost safe amphetamine never exceed the accelerate shown. besides you must obey warning signs indicating abruptness of the grade. You must use the braking effect of the engine as the principal way of controlling your speed on downgrades. The braking effect of the locomotive is greatest when it is near the governor ‘s RPM and the transmittance is in the lowest gears. Save your brakes so you ‘ll be able to slow down or stop an emergency. Shift your infection into lower gear before starting down the grade .
Roadway work zones Speed is the phone number one lawsuit of death in roadway work zones. Obey the posted amphetamine limit at all times when in a work zone. Decrease your accelerate for adverse weather conditions. Decrease your travel rapidly even further when a worker is close to the roadway .
