All commercial drivers are required to comply with the CDL medical certification requirement. This requires all CDL holders to self-certify to a single commercial operation status to obtain or maintain their CDL status.
You can now review CDL medical certification status by accessing driver eligibility here.
Medical Certification Instructions
Applicants are required to complete one of the following forms for medical certification.
Each form allows applicants to certify to one of the following CDL categories. The category that the
applicant certifies to, determines if a medical variance or a U.S. Department of Transportation (DOT)
medical examiners certificate is required.
Category 1: Non-Excepted-Interstate Commerce (CDL-4)
Most CDL holders who drive CMV’s in interstate commerce are non-excepted interstate commerce drivers. This category requires a medical examiners certificate. If CDL holders operate in both excepted and non-excepted interstate commerce, they must follow non-excepted interstate commerce guidelines and present a medical examiners certificate.
Category 2: Excepted-Interstate Commerce (CDL-10)
This certification category is for applicants that will operate their CMV for excepted activities. Applicants will be restricted to operate their CMV in the excepted activity to which they certify. This category will NOT require a medical examiners certificate, but are required to meet Texas medical standards.
Category 3: Non-Excepted-Intrastate Commerce (CDL-5 part B)
This certification category is for applicants that will only drive a CMV in intrastate commerce and are required to meet the medical requirements for Texas. A medical examiners certificate will be required.
Category 4: Excepted-Intrastate Commerce (CDL-5 part A)
This certification category is for applicants that operate a CMV only in intrastate commerce. The driver has been regularly employed operating a CMV in Texas prior to August 28, 1989 and is not operating a CMV requiring a hazardous materials placard. This category will NOT require a medical examiners certificate, but the driver is required to meet Texas medical standards.
Category 4: Excepted-Intrastate Commerce (CDL-5 part C)
This certification category is for applicants that operate a CMV only in intrastate commerce for excepted activities (oil/water well servicing and/or drilling or mobile crane operations). Applicants will be restricted to operate their CMV in the excepted activity to which they certify. This category will NOT require a medical examiners certificate, but the driver is required to meet Texas medical standards.

The driver will need to visit the driver license office to remove the intrastate restriction and certify to interstate CDL qualifications.
