Trip Permit

Maine-registered motor vehicles that travel to another IRP jurisdiction, and which have a gross weight in excess of 26,000 pounds or three or more axles on the power unit, must be registered in the IRP.

Qualified motor vehicles from another IRP jurisdiction must have Maine on the cab card or have a valid Maine IRP trip permit prior to entering Maine.

Vehicles from non-IRP jurisdictions may operate into or through Maine in interstate commerce only. Non-apportioned vehicles operating intrastate must register in Maine or obtain trip permits.

Motor vehicles are registered on the basis of combined gross weight - total weight of the vehicle and maximum load to be carried. For combination vehicles, the gross weight is on the power unit. A motor vehicle may not be operated in excess of the maximum weight allowed for its configuration without additional permits.

Readings for a tire that has the tread design running across the tire must be taken at or near the center of the tire at 2 points of the circumference not closer than 15 inches.

Maine Frost Laws

Each spring, Maine DOT evaluates potential damage to state highways and determines whether weight restrictions should be imposed to prevent damage due to freeze/thaw action.

Many municipalities undertake similar evaluations and restrictions on local road systems.

This means that a road that can carry a 15-ton load in the summer or winter may only be able to carry a 5-ton load as it thaws.

A posted state road's maximum weight limit is 23,000 pounds. The posting is temporary and is designed to protect a road while it is vulnerable.

For up-to-date road conditions and restrictions, go to: and select "trucking" at the top of the page and "Maine" at the top of the map.
