What happens to the stopping distance of an overloaded vehicle whose brakes are forced to work too hard?
- The distance stays the same and the brakes hold
- The distance becomes much shorter than normal
- The distance increases and the brakes can fail
- The brakes grip better as they warm

-
Why do empty trucks actually require greater stopping distances?
- They have less traction
- They have heavier brakes
- They absorb more heat in the brakes
- They have softer springs than loaded trucks
Show answer
Correct answer: They have less traction
Empty trucks need greater stopping distances because they have less traction, and an empty truck can bounce and lock up its wheels.

Compared with other vehicles, what do large vehicles require when managing space?
- Less space for stopping and turning
- More space for stopping and turning

-
Compared with a car, how large a gap may a large vehicle need to enter traffic?
- A much larger gap
- A smaller gap
- The same gap
- A gap only when empty
Show answer
Correct answer: A much larger gap
Because of slow acceleration and the space large vehicles require, you may need a much larger gap to enter traffic than you would in a car.

-
How does a heavy load affect the room you should allow when entering traffic?
- Allow less room because the load adds speed
- Allow the same room as when empty
- Allow more room if your vehicle is heavily loaded
- Allow more room only when empty
Show answer
Correct answer: Allow more room if your vehicle is heavily loaded
Acceleration varies with the load, so you should allow more room if your vehicle is heavily loaded.

-
Why do lightly loaded large combination vehicles lock up their wheels very easily?
- The soft suspension springs and weak brakes give too much grip
- The extra weight on the wheels gives too much traction
- The tires are always under-inflated when lightly loaded
- The very stiff suspension springs and strong brakes give poor traction
Show answer
Correct answer: The very stiff suspension springs and strong brakes give poor traction
When lightly loaded, the very stiff suspension springs and strong brakes give poor traction and make it very easy to lock up the wheels.

In any combination rig, how should you plan to brake?
- Allow a lot of following distance and look far enough ahead to brake early
- Follow closely behind the vehicle ahead and brake as late as you can
- Look only at the vehicle ahead and brake hard when needed
- Rely on the engine to slow the rig down instead of the brakes
Show answer
Correct answer: Allow a lot of following distance and look far enough ahead to brake early
In any combination rig, allow a lot of following distance and look far enough ahead so you can brake early, so you are not caught by surprise and forced into a panic stop.
