1. When it’s difficult to see, such as at dawn or dusk, a driver can increase their vehicle's visibility by:

Driving while using their lights.

Driving with their windows open.

Flashing their lights periodically.

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

2. A driver must take the HazMat knowledge test:

Once every year.

Prior to every CDL renewal.

Once every 10 years.

Only once.

You must take and pass the written English version of the HazMat knowledge test and be cleared through a federal background check before every renewal of your CDL.

3. After connecting the air lines to the trailer while coupling, you should:

Supply air to the trailer.

Chock the wheels.

Inspect the fifth wheel.

Connect the electrical cord.

Correctly following the steps to couple and uncouple trailers is vital to safely operating a combination vehicle. After connecting the air lines to the trailer while coupling, you should supply air to the trailer.

4. Place the trailer air supply control in its "emergency" position to test:

The trailer emergency brakes.

A coupling device.

The anti-lock brakes.

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.

5. If you’re unfamiliar with the area in which you must back up, you should:

Get out of your vehicle and walk around the area to become more familiar with it.

Not use both mirrors, as that can cause too much distraction.

Wait for someone else to back up in the area so you see how they do it.

Turn on your high beam headlights.

Backing is always dangerous because you cannot see everything behind your vehicle. Especially if you are unfamiliar with the area, you should get out of your vehicle and familiarize yourself with your path of travel before beginning to back up.

6. The National Response Center must be notified of an incident resulting in any of the following, except:

Death.

Injury requiring hospitalization.

Injury not requiring hospitalization.

The National Response Center must be notified of any incident that results in death; hospitalization; $50,000 or more in estimated property damage; an evacuation of the general public or closure of a major transportation route/facility for more then one hour; fire, breakage, spillage, or suspected contamination involving radiation, bacteria, or toxins. Additionally, if the carrier judges the situation to be so serious that it should be reported, it should be reported.
