Georgia CDL Test Questions 2026: What Each Test Covers

📅 Updated July 2026 📌 Source: Georgia DDS ⏱ 7 min read

All three Georgia CDL knowledge tests use the same 80% passing threshold, but the question counts and stakes for skipping each one differ meaningfully. Here's exactly what to expect on each.

In This Guide

General Knowledge Test

50 Questions 40 to Pass (80%) Required for All Applicants

Covers vehicle inspection, basic vehicle control, driving safety, cargo transport, hazardous materials awareness, and hours-of-service basics. This is the foundational test every Georgia CDL applicant must pass, regardless of class or intended endorsements.

Air Brakes Test

25 Questions 20 to Pass (80%) Required for Air Brake Vehicles

Covers air brake system components, dual air brake systems, pre-trip inspection procedures, spring brakes, and braking technique. Required if your vehicle has air brakes, including air-over-hydraulic systems.

Skipping or failing this test results in an air brake restriction on your CDL — preventing you from operating any air brake-equipped commercial vehicle until you pass it, potentially at a later date.

Combination Vehicles Test

20 Questions 16 to Pass (80%) Required for Class A

Covers coupling and uncoupling, off-tracking, jackknife and rollover prevention, and cargo/weight distribution specific to combination vehicles. Required for Class A CDL applicants operating tractor-trailer combinations.

Testing Language

Georgia CDL knowledge tests are administered in English only — a genuinely different policy than Georgia's own non-commercial driver's license exams, which are available in 26 languages. This distinction catches some applicants off guard.
