CDL Self Certification and License Classes

Certify Your Driving

Every commercial driver must self-certify to the type of commerce he or she intends to drive when applying for a Commercial Learner Permit or CDL.

Most CDL holders who drive commercial motor vehicles in interstate commerce are "non-excepted interstate" drivers and will be required to submit an Medical Examination Certificate. This becomes part of your DMV driving record.

"Excepted" drivers are not required to file an MEC under state or federal regulations. However, your employer may require an exam.

If a physical is required, you must obtain it from a physician listed in the National Registry of Certified Medical Examiners.

Which Driver Am I?

Drivers must choose whether they operate intrastate or interstate and whether the loads they haul will make them "excepted" or "non-excepted."

  • Interstate or Intrastate

    Interstate or Intrastate (Choose One)

    INTERSTATE - operating inside and outside the State of Nevada

    INTRASTATE - operating within the borders of Nevada
