Alabama CDL Permit Test - Tank

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.

Reduce your speed when traveling on surfaces that provide reduced traction. Reduce your speed by about one-third when driving on a wet road.

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

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.

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.

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.

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.
