CDL Manual — Doubles and Triples (§7)

Questions are based on Section 7 (Doubles and Triples) of the official CDL manual (AAMVA model). The Doubles/Triples (T) endorsement is a knowledge test only — there is no separate skills test for the endorsement itself — and it is given in ENGLISH (real test); our Chinese & Spanish are study aids to help you learn the English material. The manual also directs you to study Sections 2, 5, and 6. Federal rules (FMCSA, 49 CFR 391.11) require English proficiency to drive commercially.
