When stopping a tanker, you should brake:
A. Gently and well in advance — Brake gently and early when driving a tanker. Hard braking causes liquid to surge forward, pushing the vehicle and extending stopping distance.
The rule of thumb for cargo tiedowns is that you need at least one tiedown for every:
A. 10 feet of cargo, with a minimum of two tiedowns for most loads — Federal rules require at least one tiedown per 10 feet of cargo, and a minimum number based on length and weight, to keep loads secure.
What is the 'two-second rule' for following distance at highway speeds?
C. For speeds under 40 mph, allow at least 1 second per 10 feet of vehicle length; add 1 second for each 10 mph over 40 — FMCSA recommends: for speeds under 40 mph, leave at least 1 second per 10 feet of vehicle length. For speeds over 40 mph, add 1 second. A 60-foot truck at 55 mph needs at least 7 seconds of following distance.
CDL safety scenario 54: Why does liquid surge make tanker driving harder?
A. The moving liquid can push the vehicle after you brake or turn — The moving liquid can push the vehicle after you brake or turn. Commercial drivers are expected to manage this situation before it becomes a crash risk. The CDL manual emphasizes controlling the vehicle, inspecting safety-critical systems, and correcting hazards promptly.
Which type of tanker uses internal pressure to unload the cargo?
C. Pressure tanker — Pressure tankers (used for dry bulk or certain liquids like liquid propane) use internal pressure to push the cargo out. They are different from gravity or pump discharge tankers.
ABS on a commercial vehicle:
A. Helps you keep steering control by preventing wheel lockup during hard braking — ABS keeps the wheels from locking so you can steer while braking hard; it does not necessarily shorten the stopping distance.
Rollovers of doubles/triples are most likely to happen when:
B. Making sudden lane changes or taking curves too fast — Rearward amplification and high center of gravity make doubles/triples prone to rollover during sudden lane changes and curves taken too fast.
Shock absorbers should be checked for:
D. Leaks and secure mounting — Check shock absorbers for oil leaks, dents or damage, and loose or broken mounting hardware.
What is the purpose of a CMV's emergency triangles (reflective triangles)?
B. To warn approaching traffic when the vehicle is disabled on the roadway — FMCSA regulations require CMV drivers to place emergency triangles within 10 minutes of stopping on the roadway. They must be placed at 10 feet, 100 feet, and 100 feet in the opposite direction from the vehicle.
Before driving a bus, you must:
A. Ensure all passengers are seated and have seatbelts fastened where required — Ensure passengers are seated properly. Where seat belts are required, confirm all passengers have them secured before driving.
The Georgia CDL general knowledge test has 50 questions, and you need 80% to pass — at least 40 correct answers. The practice tests on this page use the same format. The 80% passing score is a federal FMCSA standard used by every state.
80%. You can miss at most 10 of the 50 questions. The readiness dashboard on this page tracks whether you're consistently scoring above that bar.
In Georgia, driver licensing is handled by the Department of Driver Services (DDS), so you'll often see the exam called the DDS CDL general knowledge test. The practice tests on this page match the official DDS knowledge exam format.
Yes. Every practice test on this page and everything in the DMVPrep iPhone app is free — no ads, no paywall, no account.
Federal motor carrier safety regulations (FMCSA) — the same rules every state's CDL exam is drawn from. Every question in the DMVPrep app cites the regulation or handbook section it comes from.
Yes — the DMVPrep app includes all 3,745+ questions in Spanish, and the whole app works in Spanish.
