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. If a trailer begins to skid, it is best for the driver to:
Release the brakes.
Quickly turn the steering wheel in one direction, then in the other.

If your trailer begins to skid, you should release the brakes to regain traction. The trailer will begin to straighten out once the wheels begin to grip the road again.

2. During a pre-trip inspection, what is the best method for checking your lights?
Parking near a mirror to look for a reflection
Activating the lights, then exiting the vehicle to check
Looking on the instrument panel to see if any warning lights are illuminated
Driving in traffic and waiting for other drivers to let you know your lights are out

During a pre-trip inspection, you should activate your lights, then get out of the vehicle to look at them.

3. When entering traffic, the driver of a double or triple needs to be aware that doubles and triples:
Need more space to merge into traffic than smaller vehicles.
Are exempt from most speed limits.
Are difficult for other drivers to see.
Are not permitted on interstates.

Doubles and triples need more space than other vehicles, both because they are longer and because their size and weight prevent them from turning or stopping suddenly. When driving a double or triple, always make sure you have enough space before entering traffic, crossing traffic, or changing lanes.

4. Alcohol is removed from the body:
By exercising.
At a fixed rate.
More quickly if the person stays awake.

The liver removes alcohol from the body at a fixed rate. Despite popular belief, tricks like drinking coffee or taking a cold shower will not speed up the process. The only way to become sober is to allow your body the time it needs to remove the alcohol from your system.

5. When making a lane change, your turn signal:
Should always be used.
Should only be used if there is traffic present.
Should only be used between dusk and dawn.

You must always properly signal before turning or changing lanes.

6. Do not base your decision to shift gears on:
The speed of your engine (rpm).
The speed of the road (mph).
The actions of the vehicle next to you.

One way to know when it is time to shift gears is to learn your vehicle's operating rpm range. You should shift up when your engine reaches the top of that range. You can also learn which speeds each gear is good for and shift up based on your speedometer.

7. When starting from a stop:
A vehicle should shift to the right.
A vehicle should be put into third gear.
A vehicle should not roll back.

To avoid hitting anything behind you, make sure that your vehicle does not roll back when you start from a complete stop.

8. Distracted drivers may be:
Staying within their lanes.
Traveling at consistent speeds.
Preoccupied with using their cell phones.
Not talking to anyone else in their vehicles.

You may be able to tell that another driver is distracted if you can see them drifting within a lane or across lane dividers; traveling at inconsistent speeds; being preoccupied with a cell phone, a map, food, or other items; or engaging in conversation with passengers.

9. A driver who stops at a green light could be:
An impaired driver.
A driver who is color blind.
A person who does not know the rules of the road.

It is important to observe other drivers' actions and identify clues that a person could be driving impaired. Drivers who have had too much to drink, are sleepy, are on drugs, or are ill can present hazards to other drivers. One sign that a driver may be impaired is that they stop in inappropriate places, such as at green traffic lights.

10. Federal and state laws require:
Drivers to regularly inspect their vehicles.
Drivers to inspect their vehicles, but only if they believe there may be a problem.
Drivers to inspect their vehicles if planning to travel out-of-state.
Drivers to inspect their vehicles, but only if they will be transporting hazardous materials.

Commercial drivers are required by federal and state laws to inspect their vehicles before every trip. Regular inspections can help drivers identify issues before they become dangerous and costly.

11. If turning to avoid a hazard:
You should brake hard.
You should not brake as it may cause the wheels to lock.
You should turn very sharply.

You should not brake while making a quick turn to avoid a hazard. Doing so could cause your wheels to lock and make your vehicle skid out of control.

12. Air brakes use ____ to function.
Compressed air
Liquid nitrogen
Carbon dioxide

The brakes in an air brake system use compressed air to function properly.

13. Routine vehicle inspections should be done to ensure:
Good gas mileage.

The most important reason to inspect your vehicle is to ensure the safety of yourself and other road users.

14. On a leaf spring:
Leaves should shift.
Leaves can be missing.
Leaves should not be broken.

When inspecting your vehicle's suspension, verify that leaf springs do not have missing or broken leaves. If at least one-fourth of the leaves in a leaf spring are missing, the vehicle will be put out-of-service until the defect is fixed.

15. Having ABS on only one axle:
Can be dangerous.
Still allows you additional control when braking.
Slows the vehicle, but cannot stop it.

If you have an Anti-Lock Braking System (ABS) equipped on only the tractor, only the trailer, or only one axle, you will still have more control over the vehicle when braking than you would without ABS. You should brake normally.

16. When you double your speed from 20 to 40 mph, your vehicle's braking distance will become ____ times longer.

If you double your speed, your braking distance will become four times longer. Similarly, the impact your vehicle would have in the case of a collision will also multiply by four.

17. Using the brakes creates heat. If too much heat is produced:
The brakes may not work.
The brakes may squeak more than usual.
The brakes will brake unevenly.

Brakes are designed to take a lot of heat, but drivers should not rely solely on the brakes to slow their vehicle. Brakes may fade and lose their ability to slow down the vehicle if they become too hot, so drivers should also rely on the engine braking effect.

18. Brake fade is a result of:
Exposure to sunlight.
Exposure to moisture.
Excessive use.
Not using the brakes enough.

If brakes are used too much, they will overheat and become less effective. This is referred to as brake fade.

19. Rust around wheel nuts may mean:
It recently rained.
The nuts are loose.
The tire is not clean.

Rust around wheel nuts can indicate that the nuts are loose. If you find rust near the wheel nuts, check their tightness before beginning to drive.

20. If you doubt that you have enough space to safely drive under a bridge or sign, you should:
Drive faster.
Drive more slowly.
Drive on the shoulder.

If you are not certain that your vehicle will fit under overhead objects, you should slow down and take a different route, if possible.
