Georgia Hazardous Materials (H) Practice Test
The endorsement for hauling placarded hazardous materials — and the hardest knowledge test most drivers ever take, because it's built on tables: hazard classes, the placarding rules, the segregation chart for what can't ride together, and shipping-paper requirements. It's also the only endorsement wrapped in federal security requirements — a TSA security threat assessment with fingerprinting comes before the state will issue it, and the endorsement must be renewed on a cycle rather than earned once. The pay bump exists precisely because the barrier is real.
Who needs it: Drivers hauling placarded loads — tankers of fuel, chemicals, compressed gases. Required before the H prints on the license.
Sample practice questions
You load 600 lbs of a Table 2 flammable liquid and 700 lbs of a Table 2 corrosive. Must you placard?
Answer: Yes, the combined Table 2 weight is 1,300 lbs — Add all Table 2 amounts: 1,300 lbs ≥ 1,001, so placards are required (a DANGEROUS placard is allowed).
With a placarded load, you must stop before a railroad crossing within:
Answer: 15 to 50 feet of the nearest rail — Stop within 15 to 50 feet of the nearest rail, then cross without shifting gears.
Security awareness training must be given to:
Answer: Every hazmat employee — All hazmat employees must receive security awareness training.
Common mistakes on the HazMat test
- Trying to memorize the whole segregation table instead of the handful of pairings the test actually probes
- Confusing when placards are required by ANY amount versus the 1,001-lb table threshold
- Forgetting the shipping-paper rules — within reach, visible, and where they ride when you leave the cab
- Not budgeting for the TSA screening timeline — the knowledge test is one step, the background check is its own clock
Studying with the full Truckcess course does double duty: the theory counts toward the federal ELDT requirement (Truckcess is listed on the FMCSA Training Provider Registry).
