Choose online practice for your CDL goal
Use individual practice subjects alongside the current Texas Commercial Motor Vehicle Driver’s Handbook. Start with the vehicle class and work you intend to do, then select the knowledge subjects and endorsements that fit that plan. Review the product information and access terms before purchasing.
A practice purchase provides study access. Texas DPS administers the official examinations and issues the permit or license. Practice access is separate from required ELDT, a skills appointment and a vehicle rental.

Connect the subjects to your vehicle
A Class A combination path includes Combination Vehicles in addition to the applicable core knowledge subjects. A Class B single-vehicle path does not include Combination in the same way. Review Air Brakes for applicable equipment, and the Passenger and School Bus subjects for the relevant endorsement goals.
Hazardous Materials, Tanker and Doubles / Triples address different equipment or cargo responsibilities. Check the credential required for your intended work before buying an endorsement subject. Read the Texas application guide for the official examination order and links to current agency instructions.

Use repeat practice to build understanding
Read the relevant handbook section first. After a practice attempt, list the topics you missed and return to the source. Explain why the safer or correct answer applies before trying again. Understanding the reason is more useful than remembering a position on the screen.
Consistently strong repeat scores can help you judge your study progress, but they cannot guarantee the result of an official examination. Allow time to revisit weak subjects and resolve questions before booking travel or equipment.
Access, demonstrations and customer experiences
Open an individual subject to review its price, try the available demonstration and decide whether the topic fits your needs. Published online test access lasts 30 days. Use the account associated with your purchase, and contact the team if you need help locating an order.
The preserved CLP customer testimonial videos describe individual experiences. Use them to prepare questions about the service while checking current requirements in the handbook. You can also compare all practice access choices in one place.
