Texas CDL FAQ

How old do I need to be to get a Texas CDL?

You must be at least 18 years old to drive a commercial motor vehicle within Texas (intrastate). To drive across state lines or transport hazardous materials, federal rules require you to be at least 21. Texas adopts the federal rule.

How long do I have to hold my CLP before taking the CDL skills test?

Federal rule (adopted by Texas) requires a minimum 14-day CLP hold before you can take the CDL skills test.

Does Texas require ELDT for first-time CDL applicants?

Yes. Federal ELDT applies in Texas. Take training through an FMCSA-registered provider before scheduling the skills test or the H/P/S endorsement test.
