Texas CDL General Knowledge Test: What to Expect
Texas CDL knowledge exams require 80% in each section. Learn the test sequence, current language rules, and how to study commercial driving topics.
Which knowledge tests do Texas CDL applicants take?
DPS lists Texas Commercial Rules, General Knowledge, Combination for Class A, Air Brake when applicable, and needed endorsements. Study the sections for your planned equipment and operation.
How long must you hold the CLP?
DPS requires at least 14 days before skills testing. The CLP is valid for 180 days or until the base license expires, whichever is earlier. Follow its supervision rules and allow enough time for training, record updates, and test availability.
When is entry-level driver training required?
FMCSA requires applicable ELDT for first Class A/B licenses, B-to-A upgrades, and first H/P/S endorsements, with stated exceptions. Use a registered provider and ensure completion is recorded before the relevant test. A study subscription does not satisfy that training requirement.
What does the CDL skills test include?
DPS assesses vehicle inspection, basic vehicle control, and road driving. Bring a suitable vehicle for the class and equipment privileges sought. Check the current procedure for your location rather than relying on an old test-pad layout or a generic parking video.
What medical information should you check?
Choose the correct self-certification category and confirm any required medical qualification in the official record. DPS uses electronic examiner reporting. Resolve missing information with the examiner and DPS before depending on a test date; carrying a paper certificate alone is no longer the accepted reporting route.
