Alabama CDL practice tests

About the Alabama CDL

The Alabama Commercial Driver's License is issued by the Alabama Law Enforcement Agency (ALEA) — Driver License Division. Like every state, Alabama follows federal CDL standards set by the Federal Motor Carrier Safety Administration (FMCSA). To be eligible for a Alabama CDL you must be at least 18 years old (21 for interstate driving or for hazardous materials transport), hold a valid Alabama driver's license, certify your medical fitness with a DOT physical, and pass the knowledge and skills exams that match the class and endorsements of license you want.

Most CDL applicants in Alabama begin with a Commercial Learner's Permit (CLP), which lets you practice driving a commercial vehicle on public roads with a fully licensed CDL holder beside you. After holding the CLP for at least 14 days, you can schedule the behind-the-wheel skills test. The skills test has three parts: a vehicle inspection, basic vehicle control on a closed course, and an on-road driving evaluation in a vehicle that represents the class of CDL you want.

For the knowledge test, Alabama uses multiple-choice questions drawn from the official handbook. Most exams require an 80% passing score. The Alabama DMV will let you re-test a limited number of times before requiring a fee or waiting period, so it pays to over-prepare. The practice questions on this page are designed to match the format and difficulty of the real exam.

Class B — A single vehicle with a gross vehicle weight rating of 26,001 pounds or more, or that vehicle towing another not exceeding 10,000 pounds. Straight trucks, large buses, dump trucks, and box trucks fall under Class B.

Class C — Single vehicle, or combination, that does not meet the definition of Class A or B but is designed to transport 16 or more passengers (including the driver) or is used to transport placardable hazardous materials.

For most working drivers in Alabama, a Class A CDL with the Air Brakes and Combination Vehicles endorsements opens the most doors. Add Hazmat for fuel, chemical, or industrial gas hauling. Add Passenger and School Bus for transit or school work.
