Texas CDL Medical Requirements and Self-Certification

Texas CDL and CLP applicants must tell the licensing agency how they operate or expect to operate a commercial vehicle. The answer determines whether federal medical qualification applies and whether a medical examiner certificate or variance documents must be associated with the driving record. A study category is not a substitute for accurately describing the driver's real work.

Interstate commerce includes driving from one state to another or to a foreign country. It can also include a trip entirely inside Texas when the cargo or passengers are part of a movement that began or will end outside Texas. Intrastate commerce remains wholly within Texas and does not meet an interstate definition. A driver who operates in both categories must select interstate commerce.

After choosing interstate or intrastate, determine whether the operation is excepted from the normal medical qualification requirement. Non-excepted interstate drivers generally must meet federal medical standards and maintain a current medical examiner certificate. Excepted categories are limited to specified operations; a driver should not choose one merely to avoid an examination.

The common framework produces four categories: non-excepted interstate, excepted interstate, non-excepted intrastate, and excepted intrastate. Texas may apply state medical requirements to intrastate operation. Choose the category from the actual commerce and work performed, then follow the medical-document requirements attached to that category.

When certification is required, the examination must be completed by an authorized medical examiner under the current federal process. A driver with a federal or state variance, such as an approved vision or skills-performance variance, must keep the supporting record current. A V restriction may indicate that medical-variance information exists on the CDLIS record.

A driver required to maintain certified medical status can become not certified when the medical certificate expires or is not properly recorded. That can lead to loss or downgrade of commercial driving privileges. Do not wait until the expiration date: schedule the examination, confirm submission, and verify that Texas DPS has updated the record.

Review self-certification whenever employment, route, cargo, passenger service, or medical status changes. Confirm whether the new work crosses state lines or forms part of interstate commerce, whether an exception actually applies, and whether a new certificate or variance is needed. Use current Texas DPS and FMCSA instructions because electronic reporting and document procedures can change.

The March 2026 DL-7C requires CDL holders to self-certify medical certification status. DPS verifies applicable training and driver-safety records electronically, including ELDT, DACH, CDLIS, and National Registry II records.
