1. When you are uncoupling a loaded trailer, lower the landing gear until:
it makes firm contact with the ground.
the pressure in the system is above 55 psi.
makes contact with the ground, and leave the trailer off the fifth wheel.
the tractor frame is under the trailer.
2. If driving a heavy vehicle, you should:
avoid braking.
stay in the left lane.
stay in the right lane.
try to pass other vehicles going uphill.
3. When parking a trailer without spring brakes, it is very important for safety that you use wheel chocks. Why?
The air could leak out of the trailer air tank, releasing its emergency brakes.
You may not notice a major leak in the service line until you try to put the brakes on.
if you don't use wheel chocks, supply air will be sent to the service line instead of going to charge the trailer air tanks.
None of the above.
4. The parking brake:
should be used when you need to apply the brakes firmly.
should be used whenever you park.
should be used when driving in bad weather.
All of the above.
5. If during vehicle inspection a tire is too hot to touch, you should:
immediately decrease air pressure.
let air out.
make sure there is enough engine oil on the tires.
remain stopped until the tire cools off.
6. When you use your mirrors while driving on the road, you should:
avoid checking them regularly.
stare for a long time at the mirror.
check them quickly.
only use the driver's side mirror.
7. When backing with a trailer, you should:
look at your line of travel before you begin backing.
make pull-ups to re-position your vehicle as needed.
check your mirrors on both sides frequently.
All of the above.
8. Strong winds can make it difficult to stay in your lane, especially when:
driving alongside other vehicles.
driving at speeds below 40 mph.
going into tunnels.
coming out of tunnels.
9. Never drive with landing gear only part way up. Why?
It may catch on railroad tracks.
It must be exactly 5 feet off the ground.
It may be harder to use.
It makes it harder to brake.
10. You are driving on a steep downgrade in the proper low gear. Your "safe" speed is 40 mph. When your speed reaches 40 mph, you should:
maintain your current speed, and apply the brakes when you reach 50 mph to gradually reduce your speed to 40 mph.
apply the brakes to quickly reduce your speed to 25 mph, and then release the brakes.
apply the brakes to gradually reduce your speed to 35 mph, and then release the brakes.
increase your speed to approximately 45 mph, and then apply release the brakes.
