As of May 21, 2014, all physical examinations to obtain a Medical Examiner’s Certificate (formally known as a DOT card) must be performed by a medical professional listed on the National Registry of Certified Medical Examiners.

Determining Your Type of Self-Certification

Do you have a Montana Interstate commercial driver license or an Intrastate (Montana-Only) commercial driver license?

Interstate-CDL-for-Med-Cert-Page

Intrastate-CDL-for-Med-Cert-Page

If you have a Montana Intrastate commercial driver license, under Montana state law your only option is to self-certify as Intrastate Non-Excepted.

If you have a Montana Interstate commercial driver license you have two options:

Option 1:  You may self-certify as Interstate Non-Excepted (90% of Montana commercial drivers are non-excepted).

OR

Option 2:  You may self-certify as Interstate Excepted IF you drive a CMV exclusively in one of the following activities:

  • As federal, state, or local government employees;
  • To transport human corpses or sick or injured persons;
  • Fire truck or rescue vehicle drivers during emergencies and other related activities;
  • Primarily in the transportation of propane winter heating fuel when responding to an emergency condition requiring immediate response, such as damage to a propane gas system after a storm or flooding;
  • In response to a pipeline emergency condition requiring immediate response, such as a pipeline leak or rupture;
  • In custom harvesting on a farm or to transport farm machinery and supplies used in the custom harvesting operation to and from a farm, or to transport custom-harvested crops to storage or market;
  • Beekeeper in the seasonal transportation of bees;
  • Controlled and operated by a farmer, but is not a combination vehicle (power unit and towed unit), and is used to transport agricultural products, farm machinery or farm supplies (no placarded hazardous materials) to and from a farm and within 150 air-miles of the farm;
  • As a private motor carrier of passengers for nonbusiness purposes; or
  • To transport migrant workers.

If you believe you qualify for excepted status, check with your employer before self-certifying as excepted. Some employers still require their drivers to be medically qualified and self-certify as non-excepted.
