California Commercial Learner's Permit & CDL Preparation California CDL Commercial Handbook
Class A

Prepare for tractor-trailer and heavy-combination operation.

Understand Class A vehicle combinations, General Knowledge, Air Brakes, Combination Vehicles, ELDT, 15-hour training, CLP and skills testing.

Typical Class A knowledge route

General Knowledge is required. Air Brakes applies when the test vehicle uses air brakes. Combination Vehicles applies to Class A combination operation. Add endorsement tests for tank, doubles/triples, passenger, school bus, or hazardous materials as needed.

Training sequence

First-time Class A applicants subject to ELDT complete theory and behind-the-wheel curricula through a registered provider. California also requires at least 15 hours of behind-the-wheel training for an original Class A or B license.

Avoid preventable restrictions

Testing in an automatic, a vehicle without full air brakes, or a non-tractor-trailer Class A combination can limit future work.
