Alabama CDL Class B Practice Test 2026

Getting your Class B Commercial Driver’s License (CDL) in Alabama starts with meeting the basic requirements. You must be at least 18 to drive within the state and 21 to drive across state lines, carry passengers, or haul hazardous materials. You will also have to provide identification documents, pay the licensing fees, and pass a vision screening. If you plan to be engaged in non-excepted commerce, you must pass a medical exam administered by a certified medical examiner. This examiner must be listed on the FMCSA’s National Registry.

The first step in the licensing process is to get your Commercial Learner’s Permit (CLP). To do this, you must pass the official general knowledge written exam at a DMV location. To remove the L restriction (which prohibits you from using air brakes) from your CDL, you must also pass the official air brakes knowledge test. A score of 80% or higher is necessary to pass each exam. Once issued, your CLP will let you practice driving a Class B commercial vehicle under supervision, but you must hold it for at least 14 days before you can schedule and take the CDL skills tests. During this time, you must also complete Entry-Level Driver Training (ELDT) from a provider listed in the Training Provider Registry (TPR).
