Questions drivers ask
- How many questions are on the Texas CDL permit test?
- The Texas CDL handbook does not publish question counts. It says the knowledge exams are multiple choice and matching, that you need 80% on each test, and that they are taken in a set order starting with Texas Commercial Rules. Counts quoted by practice sites are unofficial.

- What tests do I need for a Class A CDL permit in Texas?
- In this order: Texas Commercial Rules, General Knowledge, Combination Vehicles and Air Brakes. Endorsement tests such as Tanker or HazMat come after, only if you need them. Skipping Air Brakes leaves the L restriction (no air brakes) on your license.
