1. The height of a vehicle's center of gravity is important for safe handling. Why?

Trucks with a high center of gravity have better traction.
A high center of gravity means you are less likely to tip over.
Trucks with a high center of gravity can roll over at the posted speed limit for a curve.
All of the above.

2. Skids caused by acceleration can usually be stopped by:

taking the foot off the accelerator.
coming to a complete stop.
speeding up.
applying the brakes firmly.

3. A full tank of dense liquid (such as some acids) may:

weigh less than a tank filled with other liquids.
exceed legal weight limits.
reduce the size of the vehicle.
be subject to travel restrictions.

4. Liquid surge occurs:

if you are caught in strong winds.
in full tanks.
in empty tanks.
in partially filled tanks.

5. The only acceptable way to check tire pressure is to:

check the minimum tread depth.
use a tire pressure gauge.
push on the tire to feel the pressure.
None of the above.

6. What results from movement of the liquid in partially filled tanks?

7. To prevent fatigue during long trips you should:

8. When checking the engine compartment:

the engine should be running.
the parking brake should be on.
wheels should not be chocked.
you should put the gearshift in neutral.

9. On a tractor-trailer equipped with a trailer brake hand valve, the hand valve can be used to:

reduce the chance of the front wheels skidding.
hold compressed air.
keep from rolling back.
prevent movement of cargo.

10. Fully loaded rigs:

are much more likely to roll over than empty rigs.
are less likely to roll over than empty rigs.
are just as likely to roll over as empty rigs.
None of the above.
