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. To check the automatic transmission fluid level in some vehicles, the vehicle:
Should be parked uphill.
Should be parked downhill.
Must be washed.
May have to be left running.

For some vehicles, you may need to leave the engine running to be able to check its automatic transmission fluid level.

2. When using a turn signal, you should not:
Signal early.
Signal continuously.
Cancel the turn signal after completing the turn.
Allow the turn signal to stay on long after the turn has been completed.

Always signal well ahead of a turn or lane change. Signal continuously until you have completed the turn or lane change, then be sure to cancel the signal so you do not confuse other drivers.

3. Hydroplaning usually occurs:
When tires are properly inflated.
At speeds under 15 mph.
In areas where water collects on the road.
During the evening.

In places where water collects on the road, it is possible for a vehicle to hydroplane. Low tire pressure or worn tire tread makes this more likely to happen. If there is enough water on a road surface, hydroplaning can occur at speeds as low as 30 mph.

4. What is the only way to sober up after drinking?
Take a cold shower.
Drink coffee.

The liver removes alcohol from the body at a fixed rate that cannot be increased through tricks like drinking coffee or taking a cold shower. The only way to sober up after drinking is to wait for the alcohol to be removed from your system.

5. Check ____ to ensure that the air in your vehicle's air braking system flows to all tires.
During a trip
Before a trip
After a trip
The night before a trip

Check the air brakes on a double or triple combination during your normal pre-trip inspection. After air pressure has reached a normal level, push in the red trailer air supply knob to send air to the emergency lines. Use the trailer hand brake to send air to the service line, then open the rear shut-off valve. If air is escaping through the valve, you will know that the entire system is charged.

6. If a truck's Anti-Lock Braking System (ABS) is not working:
The truck will not have any brakes.
The truck should be driven only at slow speeds.
The truck will still have brakes.
The truck will lack brakes on its left side.

If an ABS system fails, the vehicle will still have normal braking function. The driver should continue to drive and brake as they normally would.

7. Before a vehicle with dual air brakes is driven, pressure of at least ____ should be built up in both braking systems.
10 psi
25 psi
50 psi
100 psi

Before driving a vehicle with a dual air brake system, allow time for the air compressor to build up pressure of at least 100 psi in both the primary and secondary systems.

8. The air pressure in a dual air brake system should build from 85 to 100 psi within:
Two minutes.
15 seconds.
10 minutes.
45 seconds.

When inspecting a vehicle with a dual air brake system, you should wait for air pressure to build from 85 to 100 psi in both the primary and secondary systems. This should take about 45 seconds.

9. After the engine is started, warning lights and buzzers should all:
Stay on.
Flicker occasionally.
Turn off right away.
Turn off once the vehicle begins moving.

After the engine is started, the warning lights and buzzers should deactivate immediately. The charging circuit warning, oil, coolant, and Anti-Lock Braking System (ABS) lights should all turn off.

10. What is the average driver’s reaction time?
One-sixteenth of a second
One-eighth of a second
Between three-quarters of a second and one second
Two seconds

The average driver has a reaction time of between three-quarters of a second and one second.

11. Which of the following is not an indication of damaged brakes?
Cracked drums
Shoes with oil or grease on them
Shoes worn thinly
Pads free of oil or grease

Potential problems to check for when inspecting brakes include cracked drums; shoes or pads with oil, grease, or brake fluid on them; and shoes that are missing, broken, or worn dangerously thin.

12. A vehicle inspection:
Is a waste of time.
Is helpful in identifying minor issues before they become major problems.
Should not be done by the driver.
Should be performed once a month.

A vehicle should be inspected before every trip to help ensure that any small mechanical issues are caught before they become more serious problems. It is better to discover a problem with your vehicle before a drive than after the drive has begun.

13. A vehicle inspection:
Should only be performed once a week.
Should not be done unless the driver feels qualified to perform the inspection.
Should be performed by a friend to the driver.
Should be performed before every trip.

To ensure its safe operation, a vehicle should be inspected by every driver before every trip.

14. With your low beam headlights turned on, you should be able to see about ____ ahead of your vehicle.
15 feet
75 feet
100 feet
250 feet

Low beam headlights allow you to see about 250 feet ahead of your vehicle. When driving at night, adjust your speed so that you will be able to stop in the distance illuminated by your headlights.

15. Which of the following is not a possible cause of a fire?
Under-inflated tires
Electrical system failures
Flammable cargo
Rolling down the window

Possible causes of vehicle fires include spilled fuel or improper use of flares following an crash; under-inflated tires or dual tires that touch; short circuits in the electrical system; smoking around fuel; improper fueling or loose fuel connections; and carrying cargo that is flammable, improperly sealed or loaded, or poorly ventilated.

16. When driving, it is important to:
Keep your attention focused in front of your vehicle.
Look only to the front and right side of your vehicle.
Look only to the front and sides of your vehicle.
Look to the front, sides, and rear of your vehicle.

For safe driving, it is essential that you are aware of what is happening on all sides of your vehicle. In addition to watching the road ahead, you should frequently check your mirrors to monitor the road to the sides and to the rear of your vehicle.

Remove the dolly parking brake control.
Open the air tank petcock.
Raise the dolly support.
Remove the pintle hook.

If a converter dolly has air brakes, you can release the brakes by opening the dolly air tank petcock. Releasing the dolly's brakes is the first step you should take when properly positioning the dolly in front of the rear trailer.

19. To prevent fatigue while driving, you should:
Keep the cab warm.
Keep the cab cool.
Keep the cab poorly ventilated.
Close the vents.

A hot, poorly-ventilated area can make a person sleepy. Opening a window, opening a vent, or using the air conditioning can help keep the cab cool and reduce the risk of fatigue.
