Get the Practice Test Book$12 — Instant DownloadThe real Alabama CDL knowledge test draws from 10 topic areas. This book covers all of them with original questions written to reflect the format and difficulty of what you will see at the ALEA office.
Driving safely, stopping distances, pre-trip inspection, cargo securement, shifting, alcohol rules, and hours of service.
Pressure ranges, leakage tests, spring brake activation, governor function, brake fade, and the four-part air brake check.
Coupling and uncoupling, rearward amplification, fifth wheel inspection, air line colors, and the tug test.
The 9 hazard classes, placarding thresholds, shipping paper requirements, ERG use, and HazMat parking rules.
Liquid surge, baffled vs. smooth-bore tanks, loading rules, rollover risk, and pre-trip inspection for tankers.
Rearward amplification, converter dollies, trailer positioning, crack-the-whip effect, and length limits.
