From the Online edition (October 2026) edition.
Georgia's manual: a commercial driver must be at least 18, read and speak English well enough for signs, officials and reports, be able to drive the vehicle safely, be physically qualified, hold a CLP or CDL from only one state, and not be disqualified.
Every CDL knowledge test needs a passing score of 80%; on request the examiner gives your score for each knowledge test.
Entry Level Driver Training (ELDT) must be completed before the CDL skills tests (and, since 2/7/22, formal training comes before the hazmat TSA background check); the CLP can't be held for more than one year.
A Georgia Class A or B CDL is issued for 8 years and an AP or BP learner's permit for 365 days; a hazmat endorsement expires on the threat assessment date, at most 5 years.
You may not have more than one license; a court may fine you up to 5,000 dollars or jail you for it. No one may drive a CMV without a CDL, with the same possible penalty.
Georgia's BAC effects chart: .02 a mellow feeling and slight body warmth.
Coupling steps 4–6: back slowly until the fifth wheel just touches the trailer (don’t hit it).
To couple a pintle hook: inspect it for worn, damaged or missing parts and a secure mount.
Before backing onto a drawbar coupling ball, remove the safety lock screw, loosen the second lock screw and turn the adjustment screw out at least five turns, and rotate the safety cover bar outward until it is completely open; then reverse very slowly.
To couple a gooseneck hitch: open the coupler's clamp latch and make sure the ball is lubricated.
To uncouple a gooseneck hitch: remove the safety pin and clip, rotate the handle and raise the trailer off the ball (the coupler returns to the load position by itself), then put the safety pin and clip back.
Georgia's manual asks drivers who suspect someone may be a victim of human trafficking to report it to the Georgia Human Trafficking Hotline, 1-866-ENDHTGA.
Everyone takes General Knowledge. Add Passenger for any bus, Air Brakes if the vehicle has air brakes (air-over-hydraulic included), Combination Vehicles for combinations, and a test for each endorsement you want: Hazardous Materials, Tank Vehicles, Doubles/Triples or School Bus. Georgia Commercial Driver's Study Guide Section 1

After two days, for a failed knowledge test or skills test, every time. You must pass any failed knowledge test before the skills tests, and knowledge test failures also affect the skills test wait. Georgia Commercial Driver's Study Guide Section 1
Georgia's online Commercial Driver's Study Guide: Section 1 (who needs a CDL, the tests, disqualifications and Georgia's own CDL rules), driving safety, cargo, passengers, air brakes, combination vehicles, doubles and triples, tank vehicles, hazardous materials and school buses. Georgia Commercial Driver's Study Guide Section 1
You must be on the testing computer no later than 45 minutes before the Customer Service Center closes. Customers with reading disabilities can ask for an oral test at some centers.
Four. The commercial application (CAP) you complete at a DDS center is good for four test attempts. After a fourth failure, or if 360 days pass between attempts, you start a new application and pay for it again.
18. Drivers 18 to 20 are restricted to driving in Georgia only (intrastate); after your 21st birthday you visit a Customer Service Center to have the Georgia Only restriction removed. You must already hold a regular Georgia driver's license.
14 days after it is first issued (adding P, S or N or changing the CLP class resets that date). A CLP is valid for 365 days. Georgia Commercial Driver's Study Guide Section 1
Yes, before the skills test (or the hazmat knowledge test) if you are getting a Class A or B CDL for the first time, upgrading to a higher class, or adding a School Bus, Passenger or Hazardous Materials endorsement for the first time. Training comes from a provider on FMCSA's Training Provider Registry.
A pre-trip inspection, a basic vehicle control test and an on-road test, all in the type of vehicle you want to be licensed for. The skills test fee is paid when you schedule and is charged for each attempt. Georgia Commercial Driver's Study Guide Section 1
Yes. Active-duty military, Guard and Reserve members, and those out of the military for no more than a year, can apply for the Military Skills Test Waiver. Georgia Commercial Driver's Study Guide Section 1
A Class C driver's license. Class A covers combinations over 26,001 pounds towing more than 10,000 pounds and also lets you drive Class B and C vehicles with the right endorsements. Georgia Commercial Driver's Study Guide Section 1
Georgia Department of Driver Services (DDS) lists the current fees for the commercial learner permit, the CDL tests and the license on its official fee page. The permit fee is paid before the knowledge test, again for each try, and is not refunded if you fail.
It's for driving a vehicle over 26,001 pounds, or towing more than 10,000 pounds, for non-commercial use, such as a farmer's own truck or a fire engine. You need a Georgia license, age 18 and 3 months or 3,000 miles of experience. It takes no endorsements.
All except hazmat. Every FMCSA-recognized endorsement on your out-of-state CDL carries over, but to keep hazmat you must pass Georgia's hazardous materials knowledge test. If your old state didn't take part in TSA's program, you also apply to TSA and get fingerprinted.
About 60 to 90 days. Georgia can't place the hazmat endorsement on your license until TSA has sent back the results of your fingerprint background check, so apply well before you need it.
Pass the hazardous materials knowledge test and the TSA background check with fingerprints; formal training comes first. The endorsement can't go on a CLP and expires on your threat assessment date, at most 5 years. Georgia Commercial Driver's Study Guide Section 1
Since June 18, 2025, your medical examiner's certificate is sent to DDS electronically by FMCSA through the National Registry. DDS no longer accepts it by mail, fax, email, online or in person. Georgia Commercial Driver's Study Guide Section 1
Class A and B CDLs are issued for 8 years, and a commercial learner's permit for 365 days. Georgia Commercial Driver's Study Guide Section 1
Not for through trips. Commercial vehicles and vehicles with more than six wheels stay off GA 400 and the interstates inside I-285 unless picking up or delivering, or going to their terminal, a repair shop or the driver's home inside it. Georgia Commercial Driver's Study Guide Section 1
They depend on the vehicle you test in and your status. Examples: E bars manual-shift trucks, K limits you to driving within Georgia, L and Z bar air brakes (L any, Z full air), O bars tractor-trailers, M and N limit which passenger buses you may drive, P bars carrying passengers in a bus, X bars cargo in a tank vehicle, V shows a medical variance and Y means a hearing aid is required. Georgia Commercial Driver's Study Guide Section 1
Get a new CLP by taking the knowledge test, then retake the full skills test (inspection, basic skills and road drive) in a vehicle with what you're restricted from: air brakes, a manual transmission, or a tractor-trailer joined by a fifth wheel. Upgrading from Class B to Class A works the same way.
Yes, every CDL holder files a self-certification with DDS. You're excepted if you only drive, for example, a school bus, a government or fire vehicle, a farmer's single vehicle or a 9 to 15 passenger van; anything else is non-excepted and needs a medical card.
