The steps

  1. 1

    Go to law enforcement, not the MVD. Under MCA 61-9-428 the highway patrol or a local law enforcement agency grants the waiver; guidance pointing you at the Motor Vehicle Division is wrong.

  2. 2

    Get an affidavit signed by a licensed physician, physician assistant or advanced practice registered nurse. Montana also allows a waiver for safety or security reasons, not only medical ones.

  3. 3

    Expect a written waiver rather than a certificate: the statute requires it to identify the vehicle, the owner, the reason, the effective dates, and to carry the granting officer's signature.

  4. 4

    Keep it with the vehicle, and note the effective dates — the waiver expires, and the issuing agency keeps its copy only until it does.

  5. 5

    Confirm the current certifier list with the Highway Patrol before you book the appointment. The edition we could retrieve names physicians, PAs and APRNs, where older editions named physicians alone, so the list has been widened at least once.
