100
How long after beginning a trip do you need to stop and check the cargo?
What is first 50 miles, then every 150 miles or 3 hrs (whichever comes first)
100
How would you check your truck's slack adjusters?
What is use gloves and pull hard on each slack adjuster you can reach. To check the slack adjusters, you should attempt to pull on them manually while wearing gloves. If there is an inch or more of "give," then they should be fixed, as there is an issue.
100
What does the trailer air supply control do?
What is by pushing it in, you supply the trailer with air. When you push in the trailer air supply control, it will supply the trailer with air. If you pull it out, you will cut off the air it is supplying, causing the trailer's emergency brakes to be applied.
100
Hauling liquids in tankers requires special care because of...
What is the high center of gravity and liquid movement.
100
The blind spot behind the bus could extend to how many feet?
What is 50 to 150 feet and could extend up to 400 feet, depending on the length and width of the bus.
200
If your vehicle has power steering, what must you ensure in your pre-trip external inspection?
What is that there are no leaks from the hoses and pumps. Any leaks could compromise the power steering system, putting you and others in danger.
200
When should you drain your air tanks?
What is at the end of each work day. Unless your vehicle automatically drains the air tanks, you should drain them at the end of each working day so that the moisture and oil do not freeze or coagulate and cause your brakes to then fail.
200
Where would you find the shut-off valves?
What is in the rear of a trailer. The shut-off valves are located at the rear of a trailer, since that is where they must be located to service the air lines. The shut-off valves are open except in the last trailer, in which they are closed.
200
The liquid in a tank with baffles can still have what kind of surge?
What is side-to-side. Baffled liquid tanks have bulkheads in them with holes that let the liquid flow through. The baffles help to control the forward and backward liquid surge. Side-to-side surge can still occur. This can cause a roll over.
200
The properly adjusted outside left and right side CONVEX mirrors allow visibility in what area?
What is - front of the rear tires touching the ground - the entire side of the bus up to the mirror mounts. - at least one traffic lane on either side of the bus.
300
It is ALWAYS safe to operate at legal maximum weights, true or false?
What is false; during bad weather or in mountains, it may not be safe to operate at legal maximum weights.
300
How do brakes work on a long, steep downgrade?
What is as a supplement to the braking effect of your engine. When it comes to driving down long, steep downgrades, the braking effect of your engine is what's most important, and your brakes are only a supplement to being in the proper low gear. They cannot "correct" your vehicle being in an unsafe high gear without too much pressure on your brakes.
300
To straighten out a jackknifing trailer, should you apply your hand brake?
What is no, because the brakes on the trailer wheels are what caused the skid to begin with. The jackknife was due to the wheels locking up after you had applied the brakes. Applying the hand brake might make that worse. It does not matter at this point whether you were speeding or not. The safest thing to do is to steer as normally as you can and wait for the wheels to grip the road again.
300
Where are the two main places where the hazardous material identification number appears?
What is on the shipping papers and on the package. The two main places where you must keep the hazardous material identification numbers are on your shipping papers and on the packages themselves, as these are the places that emergency personnel have been trained to check immediately.
300
The CDL manual indicates the last step on picking up students at the bus stop is as follows...
What is make a final check to see that all traffic has stopped before completely opening the door and signaling students to approach.
400
Describe the difference between blocking and bracing.
What is blocking is used in the front, back, and/or sides of a piece of cargo to keep it from sliding. Blocking is shaped to fit snugly against cargo. It is secured to the cargo deck to prevent cargo movement. Bracing is also used to prevent movement of cargo. Bracing goes from the upper part of the cargo to the floor and/or walls of the cargo compartment.
400
What do you do if you have a drunk or disruptive rider on your bus?
What is wait until you get to the next scheduled stop or well-lighted area and discharge them.
400
How do you properly back a trailer vs. a car, straight truck or bus?
What is you turn the steering wheel in the opposite direction. Once the trailer starts to turn, you must turn the wheel the other way to follow the trailer. With the car, straight truck, or bus, you turn the top of the steering wheel in the direction you want to go.
400
Your engine runs a pump when you are delivering compressed gas. Should you turn off your engine before or after you unhook the hoses after finishing that delivery?
What is turn it off before unhooking. If your engine is required to be on when you are pumping a load of compressed gas, you are always adding an extra layer of danger to a situation. Make sure that you turn off the engine before you unhook any hoses, as soon as the delivery is completed.
400
What structure supporting the fifth wheel skid plate should be checked for cracks or breaks?
What is platform. Check for proper lubrication and that fifth wheel skid plate is securely mounted to the platform, and that all bolts and pins are secure and not missing.
500
What is the difference between Gross Combination Weight Rating and Cross Combination Weight?
What is GCWR is the maximum GCW specified by the manufacturer for a specific combination of vehicles plus its loads. GCW is the total weight of a powered unit plus trailers plus the cargo.
500
When do you need to stop at drawbridges?
What is when the drawbridge does not have a signal light or traffic control attendant.
500
Explain the "crack the whip" effect and "rearward amplification." What's the difference between the two?
What is trucks with trailers have a dangerous "crack-the-whip" effect. When you make a quick lane change, the crack-the-whip effect can turn the trailer over. There are many accidents where only the trailer has overturned. "Rearward amplification" causes the crack-the-whip effect. Rearward amplification of 2.0 means that the rear trailer is twice as likely to turn over as the tractor. Triples have a rearward amplification of 3.5. This means you can roll the last trailer of triples 3.5 times as easily as a five-axle tractor-trailer.
500
How far away are you allowed to park from a bridge, tunnel, or building if you are carrying Division 1.2 or 1.3 materials?
What is at least 300 feet. When driving with a load of Division 1.1, 1.2, or 1.3 hazardous materials, which are explosives, you must park at least 300 feet away from any bridge, tunnel, or structure. You must maintain the same distance from any gathering place or open fire.
500
If worn, what can cause excessive heat buildup from a reduced ability to absorb and dissipate heat, possibly leading to loss of brake response?
What is brake drum/linings.
