Free Georgia CDL practice test online

Take a free Georgia CDL practice exam online with clear explanations—no sign-up. Coverage includes general knowledge, vehicle systems, combination vehicles, cargo, and endorsements. Then verify current requirements with Georgia Department of Driver Services.

CDL knowledge tests are federally regulated, so the passing score in Georgia is the same as everywhere else: 80% correct on every knowledge test. You must also hold a commercial learner’s permit for 14 days before the skills test.

49 CFR 383.135(a)(1) sets the CDL knowledge-test passing score at 80%. Reaching it here is not a prediction of your official result.

Commercial licensing is largely federal. Any figure above credited to a 49 CFR section applies in every state — see 49 CFR 383.135(a)(1) and 49 CFR 383.25(e). A figure credited to Georgia Department of Driver Services is Georgia’s own, and may be stricter than the federal floor. Test length, fees, and scheduling are set by Georgia Department of Driver Services (official source).

Entry-Level Driver Training comes first

Since February 7, 2022, a new Class A or Class B CDL, a class upgrade, or a first passenger, school bus, or hazardous materials endorsement requires training from a provider on the FMCSA Training Provider Registry (49 CFR 380.600). Practice questions are study material and do not satisfy that requirement.

FMCSA Training Provider Registry

You need a Georgia licence first

A commercial learner’s permit only counts if you already hold an ordinary licence from the same state (49 CFR 383.25(a)(2)). The Georgia non-commercial knowledge test runs 40 questions and needs 30 correct, with permits issued from age 15.

Sample questions

5 Georgia CDL practice questions

Try these Georgia sample questions now — each shows the correct answer with a plain-language explanation and a source section. The full 600-question bank is in the practice run.

  1. 1. A driver vehicle inspection report is normally completed:

    • ABefore every trip only
    • At the end of the driving day
    • COnce a week
    • DOnly after a breakdown

    Answer: At the end of the driving day. The post-trip report records defects found that day so they can be repaired or certified as not needing repair before the vehicle is used again.

  2. 2. The stop-light switch in an air brake system turns on brake lights when:

    • You apply the brake pedal (air pressure is applied)
    • BThe governor cuts out
    • CABS runs a bulb check
    • DThe parking brake is released

    Answer: You apply the brake pedal (air pressure is applied). Brake lights warn following drivers whenever service brakes are applied.

  3. 3. On a bus equipped with a standee line, passengers must not stand:

    • ANext to an emergency exit
    • BIn the centre aisle at any time
    • CBehind the rear axle
    • Forward of the line

    Answer: Forward of the line. The line marks the area where a standing passenger would obstruct the driver or be unprotected in a collision.

  4. 4. Supply pressure gauges tell you:

    • AHow hard you are pressing the pedal only
    • How much pressure is in the air tanks
    • COnly trailer hand-valve pressure
    • DEngine oil pressure

    Answer: How much pressure is in the air tanks. Dual systems may show two needles or two gauges—one for each half of the system.

    Source: Commercial Driver License Manual — Air brakes — supply pressure gauges

  5. 5. Baffles inside a liquid tank help control surge:

    • Forward and back but not side to side
    • BIn every direction equally
    • COnly when the tank is full
    • DSide to side but not forward and back

    Answer: Forward and back but not side to side. Baffled bulkheads have holes that slow forward and backward movement. Side-to-side surge is largely unaffected, so turns remain risky.
