|
What effects can wet brakes cause? How can you avoid these problems?
|
Water in the brakes can cause the brakes to become weak, to apply unevenly, or to grab. This can cause lack of braking power, wheel lockups, pulling to one side or the other, and jackknife if you pull a trailer. Avoid driving through puddles or flowing water if possible. If not: slow down and place transmission in a low gear, gently put on the brakes, increase engine RPMs and cross the water while keeping light pressure on the brakes. When out of the water, maintain light pressure on the brakes for a short distance to heat them up and dry them out. Make a test stop when safe to do so. Check behind to make sure no one is following, and then apply the brakes to be sure they work well. If not, try to dry them out further as described above.
|
|
|
You should let air out of hot tires so the pressure goes back to normal. True or false?
|
False
|
|
|
You can safely remove the radiator cap as long as the engine isn’t overheated. True or False?
|
True
|
|
|
What factors determine your selection of a “safe” speed when going down a long, steep downgrade?
|
Total weight of the cargo and vehicle, length of grade, steepness of the grade, road conditions, and weather.
|
|
|
Why should you be in a proper gear before starting down a hill?
|
Lowering the transmission gear will slow down the engine and lower the RPMs to a point where you can slow or stop required by road conditions.
|
|
|
Describe the proper braking technique when going down a long, steep downgrade.
|
Once the engine is in a proper lower gear apply the brakes just hard enough to feel a definite slowdown, when your speed has been reduced to approximately, five MPHs below your “safe” speed release the brakes, and when your speed has increased to your “safe” speed repeat steps one and two.
|
|
|
What type of vehicles can get stuck on a railroad-highway crossing?
|
Low snug units (lowboy, car carrier, moving van, possum-belly livestock trailer) or a single-axel tractor pulling a long trailer with its leading gear set to accommodate a tandem-axle tractor.
|
|
|

14 seconds for a single track and 15 for a double.
|
|
|
Stopping is not always the safest thing to do in an emergency. True or False?
|
False
|
|
|
What are some advantages of going right instead of left around an obstacle?
|
Going right is best if someone has drifted into your lane (that driver will most likely get back into their own lane once they realize something is wrong), if the shoulder is clear you should steer into it (no one should be driving on the shoulder of the road), and if you are blocked on both sides you should steer right (you are not forcing anyone into oncoming traffic).
|
|
|
What is an “escape ramp”?
|
Escape ramps use soft gravel that resists the motion of the vehicle and brings it to a stop and others turn uphill, using the hill to stop the vehicle and soft gravel to hold it in place.
|
|
|
If a tire blows out, you should put the brakes on hard to stop quickly. True or False?
|
False
|
|
|
How do you know if your vehicle has antilock brakes?
|
Tractors, trucks, and buses will have ABs malfunction lamps on the instrument panel. Trailers will have yellow ABS malfunction lamps on the left side, either on the front or the rear corner. Dollies manufactured on or after March 1, 1998, are required to have a lamp on the left side. As a system check on newer vehicles, the malfunction lamp comes on at start-up for a bulb check, and then goes out quickly. On older systems, the lamp could stay on until you are driving over five MPH.
|
|
|
What is the proper braking technique when driving a vehicle with antilock brakes?
|
Use only the braking force necessary to stop safely and stay in control. Brake the same way regardless of whether you have ABS on the bus, tractor, or both. As you slow down, monitor your tractor and trailer and back off the brakes (if it is safe to do so) to stay in control. There is only one exception to this procedure. If you drive a straight truck or combination with working ABS on all axels, in an emergency stop, you can fully apply the brakes.
|
|
|
How do antilock brakes help you?
|
They will help you maintain vehicle control, but not always shorten stopping distance, when you brake hard on slippery surfaces ABS helps you avoid wheel lock up and maintain control and will be able to steer around an obstacle while braking, and avoid skids caused by over braking.
|

|
|
|
What is a dual air brake system?
|
It has two separate air brake systems, which use a single set of brake controls. Each system has its own air tanks, hoses, lines, etc. One system typically operates the regular brakes on the rear axle or axles. The other system operates the regular brakes on the front axle (and possibly one rear axle). Both systems supply air to the trailer (if there is one). The first system is called the “primary” system. The other is called the “secondary” system.
|
|
|
What are the slack adjusters?
|
They are what determine how hard you have to press on the brakes to have them engage.
|
|
|
How can you check slack adjusters?
|
Use gloves and pull hard on the slack adjuster, if the slack adjuster moves more than an inch, it needs adjusting.
|
|
|
How can you test the low pressure warning signal?
|
Shut the engine off when you have enough air pressure so that the low pressure warning signal is not on. Turn the electrical power on and step on and off the brake pedal to reduce air tank pressure. The low air pressure warning signal must come on before the pressure drops to less than 60 psi in the tank (or tank with the lowest air pressure, in dual air systems).
|
|
|
How can you check that the spring brakes come on automatically?
|
Continue to fan off the air pressure by stepping on and off the brake pedal to reduce tank pressure. The tractor protection valve and parking brake valve should close (pop out) on a tractor-trailer combination and single vehicle types when the air pressure falls to the manufacturer’s specification (20-40 psi). This will cause the spring brakes to come on.
|
|
|
What are the maximum leakage rates?
|
2 psi in a minute for single vehicles and 3 psi in a minute for combination vehicles. When applying 90 or more psi to the brakes the loss should be 3 psi per minute in single vehicles and 4 psi for combination vehicles in a minute.
|
|
|
Why should you be in the proper gear before starting down a hill?
|
It will slow down the engine speed and help in continuing normal stopping distances.
|
|
|
What factors can cause brakes to fade or fail?
|
Too much heat by using the brakes too much. They can also be out of adjustment, also caused by too much heat.
|
|
|
3) The use of brakes on a long, steep downgrade is only a supplement to the braking effect of the engine. True or False?
|
False
|
|
|
4) If you are away from your vehicle only a short time, you do not need to use the parking brake. True or False?
|
False
|
|
|
How often should you drain air tanks?
|
After each working day.
|
|
|

|
|
|
You still have normal brake functions if your ABS is not working. True or False?
|
True
|
|
|
Define the danger zone. How far does the danger zone extend around the bus?
|
The danger zone is the area on all sides of the bus where children are in most danger of being hit, either by another vehicle or their own bus. The distance is up to 30 ft. from the front bumper (the first ten being the most dangerous) and 10 feet on the sides and rear of the bus. *The left side is always considered dangerous because of oncoming traffic.
|
|
|
What should you be able to see if the outside flat mirrors are adjusted properly? The crossover mirrors?
|
You should be able to see the reflection off the flat mirrors 200 feet or four bus lengths behind the bus. Along the sides of the bus, and the rear tires touching the ground. For the convex mirrors you should be able to see the entire area in front of the bus from the front bumper at ground level to a point where direct vision is possible, direct vision and mirror view vision should overlap, the right and left front tires touching the ground, the area from the front of the bus to the service door, these mirrors, along with the convex and flat mirrors, should be viewed in a logical sequence to ensure that a child or object is not in any of the danger zones.

The student should walk 10 feet away from the side of the school bus to a position where you can see them, walk to a location at least 10 feet in front of the right corner of the bumper, but still remaining away from the front of the school bus, stop at the right edge of the roadway, you should be able to see the students feet. When the students reach the edge of the roadway they should: stop and look in all directions, making sure the roadway is clear and is safe, check and see if the red flashing lights on the bus are still flashing, wait for your signal before crossing the roadway. Upon your signal, the student should: cross far enough in front of the school bus to be in your view. Stop at the left edge of the school bus, stop, and look again for you signal to continue to cross the roadway, look for traffic in both directions, making sure the roadway is clear, proceed across the roadway, continuing to look in all directions.
|
|
|
Under what conditions must you evacuate the bus?
|
Fire or danger thereof, smell of raw or leaking fuel, could the bus be hit by another vehicle, in the path of a sighted tornado or rising waters, downed power lines, stuck on a railroad crossing, the position of the bus may change and increase the danger, or a hazardous material spill.
|
|
|

|
15-50 feet before the railroad crossing.
|
|
|
What is a passive highway-rail crossing? Why should you be extra cautious at that type of crossing?
|
A passive highway-rail crossing is a one where there is only a sign and no signal or gates. You should be extra careful crossing these because you will have no extra help in knowing when it is safe to cross these tracks.
|
|
|
How should you use your brakes if your vehicle is equipped with antilock brakes (ABS)?
|
Use only the braking force necessary to stop safely and stay in control.
