What's the Passing Score on the Alabama CDL General Knowledge Test?

49 CFR Part 383 sets the 50-question, 80% format nationwide — no state, including Alabama, has any authority to raise or lower it.

What ALEA does control is everything downstream: the $25 testing fee, the $36.25 issuance fee, and critically, a CLP that runs for exactly 360 days with zero renewal option.

In a state where the CLP renews, a slow start barely matters. In Alabama, it does: every day spent retesting or waiting on a retest is a day gone from a fixed, non-extendable 360-day clock.

Let that CLP lapse before finishing the skills test, and every written test has to be retaken from zero, with a brand-new CLP issued after — there's no partial credit for tests already passed the first time around.

Air brake PSI thresholds and hours-of-service caps trip up applicants who rely on driving intuition instead of memorizing the exact numbers.

Cargo securement's mile-and-hour checkpoints (50 miles initially, then every 150 miles or 3 hours) get reversed under pressure more often than any other single fact.

Reading every explanation — not just the ones you got wrong — is what actually builds the understanding a fixed-deadline permit doesn't give you room to rebuild twice.
