43 . How can a person check for a leak in hydraulic brakes?
Remove the rear wheel and listen for a noise when the brake pedal is depressed.
Check hydraulic brakes by pumping the brake pedal three times before applying firm pressure to the pedal for five seconds. The pedal should not move. If it does, there may be a leak or some other problem in the braking system.
44 . When traveling with cargo, the cargo should be checked:
Only after arriving to the final destination.
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. The driver of a truck transporting cargo is responsible for the cargo being safely secured throughout the trip.
45 . When transporting cargo, drivers must check the securement of the cargo every:
1,000 miles.
The securement of cargo must be checked before beginning a trip, within the first 50 miles of a trip, and then again every three hours or 150 miles.
46 . The driver of a commercial motor vehicle:
Can use a cell phone at night.
It is prohibited for CMV drivers to use hand-held mobile phones while driving.
47 . In a vehicle with dual air brakes, a leak in one system ____ the second system.
A dual air brake system is made up of two separate air brake systems. If there is an air leak in one system, it may not affect the other.
48 . How should you brake if your vehicle loses its ABS?
Avoid using the brakes.
An Anti-Lock Braking System (ABS) is in place as an addition to a braking system. It intervenes to prevent brakes from locking up during hard braking. If ABS is not working, the basic braking functions on a vehicle will still remain, so the driver can continue to drive and brake normally.
49 . In very hot weather, tires should be checked regularly because:
The lug nuts may loosen.
Air expands as it gets warmer, so the air pressure in your tires could reach dangerously high levels while being used in very hot weather. If this happens, stop and let your tires cool. Do not let air out of the tires, as this could result in the pressure dropping to an unsafe level once the tires cool down.
50 . Backing with a trailer is dangerous because:
There may be extra weight in the front of the trailer.
Backing up is always dangerous because it is impossible to see everything behind your vehicle. If you must drive in reverse, use a helper, if possible.
