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 traveling long distances, you should:
Take rest breaks.
Drive as fast as possible.
Drive through the night.

To avoid becoming fatigued on a long trip, you should take a break after every 100 miles or two hours of driving. Driving through the night, or during any other time when you would normally be asleep, raises the danger of fatigue.

2. Air tank drains:
Should not be used in cold weather.
Are helpful to remove water and oil from the air tanks.
Are used to move air to the brakes.

Compressed air in an air brake system usually has a certain amount of water and oil in it. This can harm the system if allowed to accumulate. Air tanks have drain valves to aid in removing water and oil from the compressed air.

3. Black ice is:
A thick layer of ice on the road.
A thin layer of ice on the road.
Ice that is black from debris on the road.

Black ice is a layer of ice that is thin and clear enough for the road to be visible through it. The surface will look like a wet road. Always be alert to black ice if the road looks wet when the temperature is below freezing.

4. ____ is an example of required emergency equipment.
A spare electrical fuse
A loud horn
A battery-operated flashlight

All commercial motor vehicles are required to be equipped with the proper emergency equipment. This may include spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

5. What is a retarder?
A device that prevents a vehicle from going too fast
A device that prevents a vehicle from being too loud
A device that improves a vehicle's gas mileage

Retarders help to slow vehicles, reducing drivers' need to use brakes.

6. If one-fourth of the leaves in a leaf spring are missing when a vehicle is inspected:
The vehicle’s driver will be allowed to drive, but only at reduced speeds.
The vehicle will be put out-of-service until it is fixed.
The vehicle will be fine to drive since most of the spring is in place.

When inspecting a vehicle's suspension, you should look for broken or missing leaves in the leaf springs. Any defect of this kind is dangerous. If one-fourth or more of the leaves are missing from any leaf spring, the vehicle must be put out-of-service.

7. When leaving your vehicle unattended:
The parking brake should be used.
The parking brake only needs to be used if the vehicle is parked on a slope.
The parking brake should not be used, as it can damage the tires.

In general, you should always use the parking brake when parking your vehicle. However, you should not apply the parking brake if your brakes are very hot or if your brakes are wet and temperatures are below freezing.

8. To prevent your vehicle from rolling backward when beginning to move, you can:
Partly engage the clutch before taking your foot off the brake pedal.
Place the vehicle in second gear.
Use the parking brake when stopping.

To ensure that your vehicle does not roll backward when beginning to move after a stop, you should partly engage the clutch before removing your right foot from the brake pedal.

9. If a vehicle is power steering-equipped, the hoses should be:
Checked for leaks.
Securely connected to the battery.
Carrying fuel.

When inspecting a vehicle equipped with power steering, you should inspect the hoses, pumps, and fluid levels. Specifically check the hoses for leaks.

10. If driving so slowly that you could impede other drivers, you should:
Drive in the left lane.
Drive while using your four-way flashers.
Drive without using any lights.

If you must drive so slowly that you will impede the flow of traffic, you should turn on your four-way flashers to alert drivers behind you (as long as local laws allow the use of flashers).

11. On a slippery surface, stopping distance:
Is longer than on a regular driving surface.
Is not as long as on a regular driving surface.
Is about the same as on a regular driving surface.

A vehicle's regular stopping distance increases on slippery surfaces because there is less available traction.

12. 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.

13. When the spring brakes are on, you should never:
Turn on the lights.
Turn off the vehicle.
Push down the brake pedal.

Never push down the brake pedal while the spring brakes are activated. The combined force of springs and air pressure could damage the brakes.

14. If another driver is tailgating you, you should:
Move into the left lane.
Speed up.
Increase the distance between you and the vehicle ahead.

If you are being tailgated, you should increase the distance between your vehicle and the vehicle ahead. This will reduce your need to make sudden moves, and will also allow the tailgater more room to pass you. Speeding up when being tailgated is not advised because it may result in the tailgater continuing to follow you closely at the higher speed, only increasing the danger.

15. If the coolant temperature gauge goes above the highest safe temperature, you should:
Continue to drive.
Pull over and figure out what's wrong.
Run the air conditioner.

If the coolant temperature gauge goes above the highest safe temperature, you should stop driving as soon as possible and try to figure out what is wrong. There could be an issue in your vehicle that could lead to engine failure and possibly a fire.

16. When accelerating on a surface with poor traction, such as a wet road, a driver should:
Speed up quickly.
Speed up slowly.
Not be concerned about the pavement.

You should accelerate very gradually when driving under conditions that create poor traction.

17. When starting from a complete stop, a vehicle should:
Jerk forward.
Roll backwards.
Not move backwards.

To avoid hitting vehicles behind you, you must ensure that your vehicle will not roll backward when you start moving forward from a stopped position.

18. 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.

19. In a double or triple combination, the ____ trailer should be directly behind the cab.

When positioning trailers in a combination, the most heavily-loaded trailer should be the closest to the tractor. The lightest trailer should be positioned in the rear.

20. Drowsy driving is most common during:
The night.
The early morning.
The mid-afternoon.

Drowsy driving is most common during the night because people are naturally prone to be less alert in the hours during which they are normally asleep. If you must drive at night, take every precaution to prevent fatigued driving.
