Not enough to pass :-(

Ouch! While you were on a roll there for a few questions, you didn’t pass this time. But I know this test, and I think you’ll pass next time. Really.

1. When starting a vehicle, warning lights and buzzers:
Should not light up or sound.
Should turn on and shut off quickly.
Should turn on and remain on.

After starting a vehicle's engine, the warning lights and buzzers should turn on, then quickly turn off.

2. Scan the road ____ ahead of your vehicle.
Two to three seconds
Five to six seconds
12 to 15 seconds

Good drivers scan the road at least 12 to 15 seconds ahead of their vehicles. Looking ahead will allow you to identify and react to hazards before meeting them. Be sure to specifically look for vehicles that are coming onto the highway, entering into your lane, or turning.

3. When drivers turn, they usually:
Look in the direction of the turn.
Look in the direction opposite the turn.
Look behind their vehicles.

When turning, drivers usually look in the direction of their turn. If a driver fails to signal before a turn or lane change, their body movements may still provide a clue that they are planning to turn.

4. After a vehicle is started, warning lights and buzzers:
Should stay on for several minutes.
Should turn off within a few seconds.
Should stay on until manually turned off.

After a vehicle is started, the warning lights and buzzers should go out after a few seconds. If the warning signals do not turn off, there may be something wrong with the vehicle.

5. On a slippery road, a driver should:
Make turns as quickly as possible.
Refrain from passing slower vehicles.
Stop quickly.

Under slippery conditions, you should drive slowly and smoothly. Make turns as gently as possible and do not pass other vehicles unless you have to.

6. If unable to tell if the road is becoming icy and slippery, a driver:
Should try guessing.
May open their window and feel the front of the side mirror for ice.
Should look at the road closely.

If you think the road surface may be becoming icy but you are not certain, you can open your window and feel the front of the side mirror, mirror support, or antenna. If ice has formed on any of these items, the road is likely becoming icy as well.

7. When pulled off on the side of the road:
A driver should keep the driver’s side door open.
A driver should turn on the emergency flashers.
The driver should wave their arms.

If you must stop on the side of the road, make sure to use your four-way emergency flashers. This is particularly important at night.

8. If confronted by an aggressive driver, you should:
Keep your vehicle in front of them.
Make eye contact with them
Ignore their gestures.

If confronted by an aggressive driver, don't let yourself be provoked by their actions or angry gestures. Do not risk provoking the other driver by making eye contact. Get out of their way if you can do so safely.

9. On a shipping paper, the identification number, shipping name, and hazard class should:
Be abbreviated if using a small piece of paper.
Only be abbreviated if the abbreviations are easy to understand.
Never be abbreviated.

On hazardous materials shipping papers, the identification number, shipping name, and hazard class must not be abbreviated, unless specifically authorized in the hazardous materials regulations.

10. If you are turning left at an intersection where there are two available turn lanes:
It is best to use the right lane.
It doesn’t matter which lane you use.
It is best to use the left lane.

You may have to swing right to safely make a left turn. If there are two left turn lanes available at an intersection, you should always begin your turn in the rightmost lane.

11. When refueling a vehicle carrying hazardous materials:
The engine should be left on.
The engine should be turned off.
The gas nozzle may be left unattended.

If you need to refuel a vehicle carrying hazardous materials, you must first turn off the engine. While refueling, someone must be at the nozzle and controlling the fuel flow at all times.

12. When entering a curve, you should:
Shift into neutral.
Use the shoulder.

You should always slow down to a safe speed and shift into a lower gear before entering a curve.

13. Older trailers are not equipped with spring brakes. This means that if the air supply for a vehicle's air braking system leaks away:
The trailer will stop normally.
The trailer will not have brakes.
The trailer will speed up.

Older trailers do not have spring brakes. This means that if the air supply in an older trailer's air tank has leaked away, there will be no working brakes connected to the trailer and its wheels will turn freely.

14. A broken exhaust system:
Can allow poisonous fumes to enter the cabin.
Does not cause problems.
Should not be a concern.

A broken exhaust system can let poisonous fumes into a vehicle's cab or sleeper berth. Be sure to inspect your exhaust system for any loose, broken, or missing parts.

15. Alcohol begins to affect the body:
After only one drink.
After several drinks have been consumed.
At the legal limit.

Alcohol consumption impairs muscle coordination, reaction time, depth perception, vision, judgement, and inhibition. For some people, signs of impairment may begin with the first drink of alcohol. It is safest to not operate any motor vehicle after consuming alcohol in any amount.

16. Unless excepted, a shipping paper must list:
An emergency response telephone number.
The address of the shipper.
The location of fire departments along the planned route.

Unless excepted, hazardous materials shipping papers must list an emergency response telephone number.

17. If the brakes pull to one side or the other when used:
They are working properly.
They need to be checked.
They will be the most effective.

If the brakes pull to one side or the other when used, it is an indication of brake trouble.

18. What is the tractor protection valve?
A valve that keeps air in the brake system should a bad leak occur
A valve that prevents the trailer from being accidentally released
A valve that prevents the vehicle from going too fast

A tractor protection valve keeps air in a tractor or truck air brake system should the trailer break away or develop a bad leak. The valve will close automatically if the pressure drops to an unsafe level.

19. When loading liquid cargo, it is important to remember:
That there may be construction work along your planned route.
That too much cargo can slow down your vehicle.
That the liquid will expand in transit.

Factors that affect how much liquid is safe to load into your tank include how much the liquid will expand in transit, the weight of the liquid, and legal weight limits. All liquids expand at different rates, so be sure you know the rate at which your cargo will expand once you begin to drive.

20. When turning, you should:
Signal before the turn.
Turn off your turn signal just before starting the turn.
Signal only if vehicles are in front of you.

Be sure to activate the appropriate turn signal well in advance of a turn or lane change. Signal continuously throughout the turn and make sure to cancel the signal after the turn is completed, if your vehicle doesn't have self-canceling signals.
