The Texas Doubles & Triples test, explained
Texas's doubles/triples (T) endorsement is a federal add-on to a Class A CDL: pass the written test at a Texas DPS driver license office and pay the state's endorsement fee.
Every CDL knowledge test nationwide, Texas included, uses the same federal 80% passing score (49 CFR §383.135).
How to add the Texas doubles & triples endorsement
- Study the doubles & triples section of your state’s official CDL manual.
- Pass the written knowledge test at your state licensing office (80% is the federal passing score on every CDL knowledge test, 49 CFR §383.135).
- Pay the endorsement fee listed on your state’s official fee schedule (Texas Department of Public Safety (DPS)).
CDL Help has not yet built a verified, source-cited fact pack for this state — the fees and steps above are the general federal process, not this state’s specific endorsement fee or wait time. Check the official link above for the current figures.
