H HazMat N Tanker P Passenger S School Bus T Doubles/Triples

School Bus (S) requires the Passenger (P) endorsement first. Air Brakes is needed whenever your vehicle has them - skipping it adds a restriction to your license.

Alabama DMV Test FAQ

In most states you can get a CDL at 18 for driving within your state (intrastate). You must be 21 to drive across state lines, carry passengers, or haul hazardous materials. Check your state's CDL manual for exact rules.

Yes. You first pass the knowledge tests to get a Commercial Learner's Permit (CLP), practice with a CDL holder in the vehicle, and in most states must hold the CLP at least 14 days before taking the skills test.

Everyone takes General Knowledge. Class A adds Combination Vehicles, and Air Brakes if your vehicle has them. Class B adds Air Brakes. Endorsements (HazMat, Tanker, Passenger, School Bus, Doubles/Triples) each add their own test - see the path picker at the top of this page.

Typically 50 questions, and most states require 80% to pass. Endorsement tests are shorter (usually 20-30 questions, same 80% bar). Your state's CDL manual lists the exact numbers.

Yes - a TSA security threat assessment (fingerprints and background check), and the endorsement must be renewed periodically. Start the TSA step early; it can take several weeks.

No. We are exam prep only: our practice tests get you ready for the state knowledge tests. Entry-Level Driver Training (ELDT) for first-time Class A/B applicants must be completed with an FMCSA-registered training provider.

Alabama CDL Practice Test Guide: General Knowledge & Endorsements

Freight in Alabama runs from the Gulf inland, and the tests above are built to get you ready for the written exam that starts every commercial driving career in the state.

That exam is the CDL General Knowledge test: 50 questions, with 40 correct out of 50 needed to pass, the same 80 percent threshold the FMCSA enforces nationwide. Pass it and you earn your Commercial Learner’s Permit, so treat an Alabama CDL permit practice test and a general knowledge session as the same preparation. Drivers going for Class A, B, or C licenses all answer this identical written test. The class is settled by the skills exam and the vehicle you test in, not by anything on the written side.

Give real attention to vehicle inspection, basic vehicle control, shifting, managing space and speed, recognizing hazards early, and responding to emergencies. Understanding why each rule exists beats memorizing answers, and the questions here push you toward that.

Alabama’s freight mix shapes your endorsement plan. The Port of Mobile pulls containers, steel, and chemicals up I-65 and I-10, and the state’s auto plants, Mercedes near Tuscaloosa, Hyundai in Montgomery, and Honda in Lincoln, keep parts and finished-vehicle haulers busy along I-20. That work favors Combination Vehicles and Air Brakes for tractor-trailer drivers, while HazMat and Tanker matter for the chemical and fuel loads moving near the coast. Match your study to the corridor you plan to run.

The endorsements themselves, Air Brakes, Combination Vehicles, HazMat, Tanker, Doubles/Triples, Passenger, and School Bus, are separate knowledge tests, each with its own material.

The Alabama Commercial Driver License Manual lays out every one of these topics, and you can run the free Alabama CDL practice tests above without a login. Use one as a sample CDL exam to gauge where you stand, and once your scores hold steady, schedule your CDL skills test with ALEA.
