Tennessee CDL Permit Test - Double

If you must drive slowly, you should use your emergency flashers to warn other drivers. Be sure that the use of emergency flashers is permitted by local laws.

Before a trip, you should check each slack adjuster after parking, setting wheel chocks, and disengaging the parking brake. Pull the slack adjusters to make sure that they do not move more than about one inch from where the push rod is attached. If they move more than one inch, they may be out of adjustment and will need to be fixed.

To reduce the risk of a rollover when pulling trailers, you should drive slowly when turning, drive slowly on curves, and generally steer gently and smoothly. When loading the trailers, you should keep the cargo as low to the ground as possible.

There are several reasons why driving at night is more difficult than driving during the day. It is more difficult for drivers to see hazards, the glare of headlights can affect drivers' vision, and there are more fatigued drivers on the road.

During an inspection, ensure that the wheel bearing/seals are not leaking.

There may be a delay of a few seconds between the sound of a tire failing and the time that the vehicle is affected by the tire failure. Because of the short delay, a driver may initially believe that the sound came from another vehicle.

Once you have begun to drive after a tire has been changed, you should stop after a short distance to recheck the tightness of the lug nuts.
