What Is a Class A CDL?
A Class A CDL (Commercial Driver’s License) allows you to operate any combination of vehicles with a gross vehicle weight rating (GVWR) of 26,001 lbs or more, as long as the vehicle being towed weighs more than 10,000 lbs. Getting one requires completing ELDT training and passing the Texas CDL skills test.
In plain language: Class A covers big rigs, 18-wheelers, semi-trucks, and tractor-trailers. It’s the license that most professional truck drivers hold — and the one that leads to the best-paying driving jobs.
A Class A CDL holder can also legally drive Class B and Class C vehicles. It’s the highest-tier commercial license available and gives you the most job flexibility.

Frequently Asked Questions
A Class A CDL allows you to operate any combination vehicle with a GVWR of 26,001 lbs or more when the towed unit exceeds 10,000 lbs. This covers tractor-trailers, 18-wheelers, and flatbeds. It is the highest tier of commercial license — holders can also legally operate Class B and C vehicles.
You must be at least 21 to drive interstate (across state lines). If you only plan to drive within Texas (intrastate), you can get a Class A CDL at 18. Note that most carriers require drivers to be 21 regardless of intrastate eligibility, so interstate driving is typically the practical target.
Private Class A CDL programs in Texas typically cost $3,500 to $8,000. Community college programs run $2,000 to $5,000. Company-sponsored training is available at no upfront cost in exchange for a post-graduation work commitment of 6 to 24 months. See our full CDL training cost guide.
New Class A CDL drivers in Texas typically earn $60,000 to $75,000 in their first year. Experienced drivers earn $80,000 to $95,000. Specialized roles like OTR long-haul, Hazmat, or tanker can exceed $100,000 annually. See full Texas CDL salary data.
