43 . Rough acceleration:
Rough acceleration can cause mechanical damage, so be sure to accelerate smoothly and gradually.
44 . When an S-cam turns inside a brake drum, the S-cam:
When a brake pedal is pressed and the S-cam is turned, the S-cam presses the brake shoes against the inside of the brake drum. This causes friction and will cause the vehicle to slow.
45 . Front wheel braking works:
Front wheel braking is effective under all road conditions. It is unlikely that you will experience a front wheel skid, even on ice.
46 . During a static leakage test, what is the maximum leakage rate that is safe for a double combination vehicle?
When performing a static leakage test on a double combination vehicle with air brakes, the leakage rate should be no more than 3 psi in one minute. If the air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.
47 . Who may operate a vehicle that is transporting hazardous materials?
Only a driver with a hazardous materials endorsement on their CDL may operate a vehicle carrying hazardous cargo.
48 . If you must drive in reverse, using driver's side backing:
If you must back up, it is safest to back toward the driver's side of the vehicle. This way, as the driver, you will have the best possible view of your path of travel.
49 . What is brake lag?
Because air takes time to flow through the air lines to the brakes, air brakes cannot begin working instantly. There is often a brake lag of at least one-half of a second between the moment the brake pedal is pressed and the moment the brakes begin to work.
50 . If turning to avoid a hazard:
You should not brake while making a quick turn to avoid a hazard. Doing so could cause your wheels to lock and make your vehicle skid out of control.
