CDL General Knowledge

Front

What are the three components that make up total stopping distance for a truck or bus?

Back

Perception distance, reaction distance, effective braking distance.

Front

What is the safest way to merge onto a road?

Back

Wait for a large enough gap in traffic to enter the road.

Front

What steering issue should be fixed before driving a vehicle?

Back

Steering wheel play of more than 10 degrees (2 inches on a 20 inch wheel).

Front

Define perception distance in the context of driving.

Back

Perception distance is the distance a vehicle travels while the driver is recognizing a hazard and deciding to react.

Front

What is reaction distance?

Back

Reaction distance is the distance a vehicle travels from the time the driver decides to brake until the brakes are applied.

Front

Explain effective braking distance.

Back

Effective braking distance is the distance a vehicle travels while it is coming to a complete stop after the brakes are applied.

Front

What factors can affect perception distance?

Back

Factors include visibility, driver attention, and the speed of the vehicle.

Front

How does speed influence total stopping distance?

Back

As speed increases, both perception and reaction distances increase, leading to a longer total stopping distance.

Front

What is the importance of checking the exhaust system during a pre-trip inspection?

Back

Checking the exhaust system ensures there are no leaks or excessive emissions, which can indicate mechanical issues.

Front

What does it mean if there is oil on the tie rod during an inspection?

Back

Oil on the tie rod may indicate a leak or failure in the steering system, which needs to be addressed.
