About the General Knowledge Test in Texas
The General Knowledge test is required for all CDL applicants in Texas. It covers traffic laws, safe driving techniques, vehicle inspection procedures, cargo handling, and federal regulations every commercial driver must know.
The General Knowledge test is part of the CDL written exam administered by the Texas Department of Public Safety. You must pass this test along with the other required written tests to receive your Commercial Learner's Permit (CLP) in Texas.
Our practice questions are built from the official Texas CDL handbook and federal FMCSA regulations. Each question includes a detailed explanation to help you understand the material, not just memorize answers.
