Medical Exam

Obtain valid Medical Examiner’s Certificate (MEC)

MEC Requirements

The vast majority of applicants for a Class A, B, or C, Interstate or Intrastate, CDL will be required to have a valid MEC.

You'll need to obtain your certificate and have it with you when you apply.  Note that the physical must be performed by a medical professional listed on the National Registry of Certified Medical Examiners, per 49 CFR § 391.43. So be sure to ask when you make an appointment for the physical.
