Registering Your Vehicles for Interstate Operations.

You must use IRP registration if your vehicle travels in Maryland and in other IRP jurisdictions, and it is used for the transportation of persons for hire, or it is designed, used or maintained primarily for the transportation of property, and

  • it is a power unit having two axles and a gross vehicle weight or registered gross weight in excess of 26,000 pounds, or
  • it is a power unit having three or more axles, regardless of weight, or
  • it is used in combination, when the weight of such combination exceeds 26,000 pounds gross vehicle weight
  • IRP is optional for two axle vehicles, or combinations thereof, having a gross weight of 26,000 pounds or less.

To process applications online, and to obtain additional information, please visit MVA's Apportioned Registration website.

Trip Permits

An out-of-state vehicle operator must obtain a Maryland 72-hour Trip Permit prior to driving the vehicle in Maryland when all of these conditions are true:

  • the vehicle is registered in another jurisdiction; and,
  •  the vehicle meets the criteria for apportioned (IRP) registration, but is not authorized to travel in Maryland (vehicle may or may not have an apportioned registration in the other jurisdiction); and,
  • the vehicle operator wishes to drive the vehicle in Maryland for only a brief period of time (less than 3 days).

Note that the use of a Maryland 72-hour Trip Permit is only recommended when the out-of-state vehicle will be driven in Maryland less than three (3) times a year. For more details on obtaining an IRP Trip Permit, contact MVA at 1-800-950-1MVA (1682) or at www.marylandmva.com
