1. If you perform the skills test in a vehicle that is not equipped with air brakes:
you will be required to operate a CMV without hydraulic brakes.
you will be restricted from operating vehicles with air brakes.
you will be required to operate vehicles with air brakes.
you will be required to take the tank vehicle test.
2. Your vehicle has hydraulic brakes. When you press the brake pedal while driving and the pedal goes to the floor, remember that:
shifting into neutral may help slow the vehicle.
the parking brake should never used to slow the vehicle.
pumping the brake pedal may generate enough hydraulic pressure to stop the vehicle.
All of the above.
3. Most heavy-duty vehicles use:
triple air brake systems.
pump-the-brake systems.
dual air brake systems.
single air brake systems.
4. What factors can cause brakes to fade or fail?
Not taking your foot off the accelerator.
Not pressing the brake pedal hard enough.
Going too slow.
Overheating, low air pressure or water in the air tanks.

helps you avoid wheel lock up.
reduces the risk of ice in air brake valves during cold weather.
reduces the risk of having an accident due to drowsy driving.
helps keep the engine cool, as well as lubricating it.
