Describe the operation you plan to perform
Interstate and intrastate describe the operation, not simply whether a driver prefers local work. Commercial drivers should confirm the appropriate self-certification category with the licensing agency and review the rules for the work they intend to perform. A job description alone may not answer every regulatory question.
Discuss the movement of the freight or passengers, the routes, the employer’s operation, and any applicable exceptions. Texas DPS’s medical-certification guidance explains its self-certification categories and the records associated with them.
Review age, medical and license limitations
Different categories can carry different requirements and limitations. Use the current agency guidance to check age, medical certification and any restriction that applies to you. Do not rely on an older webpage that lists a single age or medical rule for every driver.
If your intended work changes, ask whether your self-certification or license record must be updated. Confirm the answer before accepting an assignment that may fall outside your present credential or restriction.
Connect the decision with your preparation
Choose the CDL class and endorsements based on the actual vehicle and work. Then organize your permit study, applicable training, and skills appointment. A Class A or Class B practice subject does not by itself determine whether an operation is interstate or intrastate.
When arranging a rental, explain your license goal and current permit. Ask about the vehicle configuration and the terms of the reservation. For a question about your legal operating category or eligibility, use Texas DPS or FMCSA rather than treating a rental confirmation as a regulatory decision.
