22 . The leakage rate for a triple combination vehicle with air brakes should be no more than ____ in one minute during a static leakage test.
When performing a static leakage test on a triple combination vehicle with air brakes, the leakage rate should be no more than 5 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.
23 . Air tank drains:
Compressed air in an air brake system usually has a certain amount of water and oil in it. This can harm the system if allowed to accumulate. Air tanks have drain valves to aid in removing water and oil from the compressed air.
24 . Which of the following is not part of a vehicle’s air brake system?
Components of an air brake system include an air compressor, an air compressor governor, air storage tanks, air tank drains, an alcohol evaporator, a safety valve, a brake pedal, foundation brakes, supply pressure gauges, an application pressure gauge, a low air pressure warning signal, a stop light switch, a front brake limiting valve (on some older vehicles), spring brakes, and parking brake controls.
25 . If the low pressure warning signal activates while you are driving, you should:
If the low pressure warning signal activates while you are driving, it is important that you safely exit the roadway as soon as possible and park your vehicle. If the air pressure gets too low, the brakes will no longer work well enough for you to stop safely.
26 . When driving on a long downhill slope, you should brake by:
When approaching a long downgrade, you should shift into a lower gear then use proper braking techniques. Using the brakes alone could cause them to overheat and fail. The braking power of the engine, which is maximized by being in a lower gear, will be the principal way of controlling your speed on a downgrade.
27 . How are violation points against a CDL calculated?
Legal violations while operating a motor vehicle will result in points against a driver's license. Violations that occur while operating a commercial motor vehicle will incur points at one and a half times their original value.
28 . Cargo being transported should be checked:
Cargo should be inspected before beginning a trip, within the first 50 miles of the trip, and every three hours or 150 miles traveled thereafter. Cargo should be inspected every time the driver stops to take a break. The driver of a truck transporting cargo is responsible for the cargo being safely secured throughout the trip.
