19 . Front brake limiting valves were intended to:
Remove uncertainty when applying the brakes.
Some older vehicles with air brakes have front brake limiting valves. These valves were intended to reduce the risk of front wheels skidding. However, research has shown that such devices are unnecessary, so they should be left in the "normal" position.
20 . All air tanks must include:
A warning sticker.
Air brake system tanks must contain drain valves. These valves are used to drain accumulated oil and water from the tanks and may be either manually or automatically operated.
21 . Friction inside a brake drum is caused when the brake shoes and linings:
Create excess heat.
Friction inside a brake drum is caused when the brake shoes and linings push against the inside of the drum. The friction in the drums will slow and stop the vehicle.
22 . During a static leakage test, the maximum leakage rate for a double combination vehicle is:
4 psi in one minute.
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 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 . What do anti-lock brakes do?
Prevent a vehicle from accelerating while traveling downhill
The function of an Anti-Lock Braking System (ABS) is to prevent the vehicle's wheels from locking up from hard brake application.
24 . Before driving a vehicle with air brakes, you should ensure that the spring brakes come on automatically when:
Driving uphill.
Before driving a vehicle with air brakes, you should ensure that the spring brakes come on automatically when air tank pressure falls to a level between 20 and 45 psi. You can do this by chocking the wheels and releasing air from the braking system by stepping on and off the brake pedal. Once the pressure drops to an unsafe level, the parking brake valve should pop out and spring brakes should come on.
25 . If the safety relief valve in an air brake system is releasing air:
The safety relief valve in an air brake system releases air if necessary to prevent pressure in the system from becoming too high. If the valve starts releasing air, there is something wrong. Have a mechanic fix the problem.

Each endorsement requires an additional knowledge test.
The Class A CDL skills test encompasses three main areas. The pre-trip vehicle inspection tests your ability to assess if your vehicle is safe to drive. The basic controls test assesses your ability to control the vehicle, back up, and perform turns. The on-road driving test evaluates your driving skills in various traffic situations, including left and right turns, intersections, railway crossings, and highways.
