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 an Anti-Lock Braking System (ABS) is equipped on a trailer but not on a tractor:

The truck should not be driven because ABS needs to be on both the tractor and trailer.

The truck should be driven more slowly than usual.

The tractor should not be used and a new tractor with ABS should be located.

The tractor and trailer can still be used together.

A vehicle being equipped with anti-lock brakes on only the tractor or only the trailer provides additional control during braking.

2. How often do hazardous materials employees need to be trained?

At least once a week

At least once every three years

At least one every 10 years

Employees who work with hazardous materials must be trained and tested at least once every three years.

3. You may be an aggressive driver if you:

Expect delays on your drive.

Slow down and maintain a reasonable following distance.

Make hand gestures that could anger other drivers.

Avoid being an aggressive driver by being realistic about your travel time, making allowance for delays, maintaining reasonable following distances, and not making hand gestures that could anger another driver.

4. An Anti-Lock Braking System (ABS):

Is not available for most trucks.

Is not helpful in most situations.

Is required on newer trucks.

Beginning between 1997 and 1999, most commercial vehicles, trailers, and dollies are required to be equipped with ABS.

5. If planning to change lanes, your mirrors should:

Not be checked.

Be checked as usual.

Be checked more often than usual.

While regular mirror checks should be part of your normal scanning routine, be especially sure to check your mirrors when changing lanes.

6. If transporting a package that contains radioactive materials, it is important to know that:

Radiation will pass through to other packages.

The packages should be carried in the cab.

The packages should be loaded on their side.

You cannot use bridges.

Radiation surrounds packages of radioactive materials and passes through to other nearby packages. To address this, the number of radioactive packages that can be loaded together is limited.

7. The service air line is attached to the:

Relay valves.

Supply line.

Emergency air line.

Steering wheel.

The service air line carries air and is controlled by either the foot brake or trailer hand brake. The service air line is attached to relay valves, which allow the trailer brakes to be applied quickly.

8. An air supply control lever should be in its "normal" position when you are:

Changing a tire.

Applying the trailer emergency brakes.

Pulling a trailer.

Using your spring brakes.

Tractor protection controls in older vehicles may be operated by levers instead of knobs. If an air supply control is set in its "normal" position, it is properly set for you to pull a trailer.

9. When driving:

It is best to hide your intentions from others.

You should only use turn signals if there are vehicles near you.

You should not use turn signals in construction zones.

You should always use turn signals to warn others about your intentions.

It is important to communicate your intentions to others on the road. Make sure to signal before turning or changing lanes, even if no other vehicles are nearby.

10. When transporting cargo, drivers must check the securement of the cargo every:

10 miles.

150 miles.

500 miles.

1,000 miles.

The securement of cargo must be checked before beginning a trip, within the first 50 miles of a trip, and then again every three hours or 150 miles.

11. If a package of hazardous materials is not large enough to hold a label, it should be labeled:

With a barcode.

With a tag.

By being placed in a certain part of the trailer.

If a hazardous materials label will not fit onto a package, it may be placed on a tag that is securely attached to the package.

12. Stopping distance can be affected by:

Speed.

Number of passengers.

Time of day.

Traffic.

Factors that can affect stopping distance include your vehicle's speed, its weight, and how slippery the road surface is.

13. If you need to travel down a hill, you should switch into a lower gear:

After you start moving downhill.

As you go downhill and pick up speed.

Before you start moving downhill.

Near the bottom of the hill.

Always downshift before beginning to drive downhill. Forcing an automatic transmission into a lower gear at a high speed could damage the transmission and also lead to a loss of ability to engine brake. Drive at a speed that will allow you to control your vehicle without overusing your brakes. When determining a safe speed to drive, you should take into account the steepness of the grade, the length of the grade, the weight of your vehicle, road conditions, and weather conditions.

14. Which of the following is not a problem?

Loose or broken exhaust pipes

Loose or broken mounting brackets

Exhaust parts rubbing against fuel system parts

Exhaust system parts that are not leaking

When inspecting an exhaust system, you should verify that parts of the system are not loose, broken, or missing. The system's parts must be properly mounted and should not be rubbing against moving parts of the vehicle.

15. Pull out the trailer air supply control to test:

The parking brake.

The trailer emergency brakes.

The trailer service brakes.

The landing gear.

Be sure to test the trailer emergency brakes before beginning a trip. After ensuring that the trailer rolls freely, you can test the emergency brakes by pulling out the trailer air supply control, or placing it in the "emergency" position. Pull forward slightly with the tractor and make sure the trailer does not move.

16. When it is difficult to see other vehicles, such as at dawn or dusk, you should:

Keep your lights off.

Turn your lights on.

Drive on the shoulder.

When driving at dawn, at dusk, or in inclement weather, you should use your headlights on their low beam setting to increase your visibility.

17. What is Gross Combination Weight?

The total weight of the powered unit, trailer, and cargo

The total weight of a single vehicle without its load

The maximum weight allowed by the manufacturer

Gross Combination Weight (GCW) is the total weight of a powered unit, its trailer(s), and the cargo being carried.

18. When applying your brakes, the vehicle should:

Pull to one side.

Squeak.

Not pull to either side.

Your vehicle pulling to one side or the other while you are braking can indicate trouble with the brakes.

19. If brakes overheat while going down a downhill grade, they may:

Get sticky.

Stop working.

Squeak.

Overuse of the brakes may cause them to overheat, making them less effective. This is known as "fade."

20. A manifest for transporting hazardous waste:

Must be signed by hand.
