A Class A license is for drivers who operate the largest commercial vehicles on Texas roads
A Class A driver license in Texas authorizes you to drive any single vehicle or combination of vehicles with a gross combined weight rating (GCWR) of 26,001 pounds or more — provided the towed vehicle weighs more than 10,000 pounds. In plain terms: if you're driving a semi-truck with a trailer, a tractor pulling multiple trailers, or any heavy commercial rig, you need a Class A.
This is the highest commercial license tier in Texas. It covers more vehicle combinations than a Class B or Class C, and it's required by federal law if you're operating these vehicles for compensation. You cannot straightforward upgrade from a regular driver license — you must pass a written test, a skills test, and a medical examination specific to commercial driving.
The Class A is not the same as a regular driver license with a commercial endorsement. It is a separate license category that replaces your standard license while it is valid. You cannot hold both at the same time.
Key Takeaways
- A Class A license covers semi-trucks, tractor-trailers, and any combination vehicle weighing 26,001 pounds or more, as long as the towed unit exceeds 10,000 pounds.
- You must be at least 18 years old to obtain a Class A in Texas, though some employers and the military require you to be 21.
- The process requires passing a written knowledge test, a pre-trip vehicle inspection, a basic control test, and a road test — all specific to commercial driving.
- You must obtain a medical certificate from a Federal Motor Carrier Safety Administration (FMCSA) certified examiner before you can take the skills tests.
- A Class A license is valid for five years in Texas and must be renewed in person at a Texas Department of Public Safety (DPS) office.
Age requirements and who can get a Class A
You must be at least 18 years old to obtain a Class A license in Texas. However, many trucking companies and freight carriers will not hire drivers under 21, and some states restrict interstate commerce for drivers under 21. If you plan to work across state lines or for a major carrier, expect the employer requirement to be higher than the state minimum.
You must also hold a valid Texas driver license (Class C) before you can test for a Class A. You cannot skip straight to commercial licensing. Your regular license must be valid and free of certain disqualifications — for example, you cannot have a suspended license or an active DUI conviction within the past 10 years.
If you are not yet a Texas resident, you can still obtain a Class A if you meet the age and medical requirements, but you will need to establish residency or have a valid out-of-state license to begin the process.
The medical certificate requirement
Before you can take any Class A skills test, you must obtain a medical certificate from an FMCSA-certified medical examiner. This is not optional and not something your regular doctor can provide. The examiner checks your vision, hearing, blood pressure, and overall fitness to operate a commercial vehicle safely.
The medical exam costs between $100 and $200, depending on the examiner. You pay out of pocket — the state does not cover this cost. Once you pass, the examiner issues a Medical Certificate (Form MCSA-5875), which is valid for two years. You must carry this certificate with you whenever you drive a commercial vehicle, and you will need to show it when you renew your Class A license.
If you fail the medical exam, you can retest with a different examiner or address the medical issue and try again. Some conditions — such as certain seizure disorders or untreated sleep apnea — may permanently disqualify you from commercial driving.
Written test, vehicle inspection, and skills tests
The Class A licensing process in Texas involves four separate tests, all of which you must pass:
- Written knowledge test: You answer 50 multiple-choice questions about commercial driving rules, vehicle maintenance, cargo safety, and hazardous materials (if you want a hazmat endorsement). You must score at least 80 percent to pass. The test covers Texas and federal regulations.
- Pre-trip vehicle inspection test: You walk around and inspect a commercial vehicle, pointing out safety features and identifying any defects. You must demonstrate knowledge of brakes, lights, tires, coupling devices, and emergency equipment. This test is not graded pass/fail — it is a demonstration of competency.
- Basic control test: You operate a commercial vehicle in a controlled environment (usually a closed course or parking lot) to show you can handle the size and weight of the vehicle. You perform tasks like backing up, turning, and parking.
- Road test: A DPS examiner rides with you on public roads for about 30 minutes while you demonstrate safe driving, proper use of mirrors, lane changes, and compliance with traffic laws.
You must pass all four tests to receive your Class A license. If you fail any one, you can retake only that test — you do not have to repeat the others. There is no limit to how many times you can retake a failed test, but you must wait at least one day between attempts.
Endorsements and restrictions that may explore
Your Class A license can include additional endorsements that expand what you are legally permitted to transport. The most common endorsement is Hazmat (H), which allows you to carry hazardous materials. To add Hazmat, you must pass an additional written test and a background check conducted by the Transportation Security Administration (TSA).
Other endorsements include Tanker (T) for transporting liquids in bulk, Passenger (P) for carrying 16 or more people, and Double/Triple Trailers (N) for towing multiple trailers. Each endorsement requires a separate written test. You can add endorsements when you first obtain your Class A or at any time during the license validity period.
Certain medical conditions or traffic violations may result in restrictions on your Class A license. For example, if you fail the hearing portion of your medical exam but pass the vision and other components, you may receive a license with a hearing restriction, meaning you must use a hearing aid while driving.
Cost, validity, and renewal
The total cost to obtain a Class A license in Texas varies because it includes multiple components you pay separately:
- Medical certificate: $100–$200
- Written test fee: included in DPS licensing fee
- Skills tests (vehicle inspection, basic control, road test): included in DPS licensing fee
- Class A license issuance: approximately $60–$90 (varies by county)
Your Class A license is valid for five years from the date of issuance. You cannot renew it by mail or online — you must appear in person at a DPS office. When you renew, you must provide a current medical certificate. If your medical certificate has expired, you must obtain a new one before you can renew your license.
If your license expires while you are out of state or unable to renew, you have a grace period of up to 60 days to renew without penalty. After 60 days, your license is considered invalid, and you cannot legally operate a commercial vehicle.
Differences between Class A, B, and C commercial licenses
Texas offers three commercial license classes, each covering different vehicle weights and combinations. Understanding the differences helps you determine which license you actually need.
| License Class | Vehicle Type | GCWR or Weight Requirement |
|---|---|---|
| Class A | Semi-trucks, tractor-trailers, doubles, triples | 26,001+ lbs GCWR; towed vehicle 10,001+ lbs |
| Class B | Single large trucks, buses, straight trucks with trailers | 26,001+ lbs GCWR; towed vehicle under 10,001 lbs |
| Class C | Small commercial vehicles, hazmat vehicles under 26,001 lbs | Under 26,001 lbs GCWR |
If you are unsure which class you need, weigh your vehicle and check the manufacturer's specifications for GCWR. Your employer or the vehicle owner can also tell you which license class is required.
Frequently Asked Questions
Can I drive a Class A vehicle with a regular driver license?
No. Operating a commercial vehicle that requires a Class A license without one is illegal and can result in fines, criminal charges, and civil liability if an accident occurs. Your insurance will not cover you if you are driving without the proper license class.
How long does it take to get a Class A license from start to finish?
The timeline depends on how quickly you schedule tests and pass them. Most people complete the written test and medical exam within one to two weeks, then schedule the skills tests within another two to four weeks. If you pass all tests on the first attempt, you can have your license within a month. If you fail and retake, add one to two weeks per retake.
Do I need a Class A if I only drive locally and not across state lines?
Yes, if your vehicle meets the weight requirements. The Class A requirement is based on vehicle weight and configuration, not on where you drive. A semi-truck pulling a trailer is a Class A vehicle whether you drive it locally or interstate.
What happens if my medical certificate expires while I am driving?
You cannot legally operate a commercial vehicle once your medical certificate expires. You must renew it before you drive again. If you are caught driving with an expired medical certificate, you can be cited and your license may be suspended.
Can I add endorsements after I receive my Class A license?
Yes. You can add endorsements (Hazmat, Tanker, Passenger, or Double/Triple Trailers) at any time by passing the required written test and, for Hazmat, the TSA background check. You do not have to add them all at once.
