Texas CDL Practice Test
The Texas CDL knowledge tests are administered by the Texas Department of Public Safety (TxDPS) using the Texas Commercial Motor Vehicle Drivers Handbook. Texas is one of the biggest CDL markets in the country, and the state follows the AAMVA model manual — the same FMCSA core content used everywhere, with Texas-specific rules layered on top.
This free Texas CDL practice test covers every knowledge exam Texas gives: General Knowledge, Air Brakes, Combination Vehicles, and all endorsements. Every question is built from public FMCSA regulations and the current TxDPS CDL Handbook.
