Maine · Oversize & Overweight

Maine Oversize & Overweight Permits filed with the Maine BMV for you, 24/7

In Maine, a load over 8 ft 6 in wide, 13 ft 6 in high or the legal weight needs an overlimit permit from the Bureau of Motor Vehicles, issued on MaineDOT's advice. The Maine Turnpike issues its own permit, good for one day. Send us the load and route: our permit desk quotes the price and files every permit the trip needs.

Routes and road rules

Where Maine routes add their own rules

The Turnpike, I-95 in summer, the interstates and posted spring roads each change how a Maine move is planned.

  1. Maine Turnpike

    Moves run half an hour before sunrise to half an hour after sunset, and no Turnpike permit is issued over 14 ft 6 in wide.

    Height:13 ft 6 in, without the extra 6 in of load allowed on other roads.

  2. I-95 on summer Saturdays

    From June 3 to August 26, Saturday travel on I-95 ends at 9 a.m. instead of noon.

    Sundays:Moves in July and August need MaineDOT pre-clearance.

  3. Maine's interstates

    A 3-axle tractor with a tri-axle semitrailer may gross 100,000 lbs on the interstate system in Maine too. Escorts for loads 16 ft wide or 125 ft long there come only from Maine State Police.

    Notice:Three working days for a State Police escort.

  4. Posted roads and bridges in spring

    An overlimit permit does not exempt a load from posted restrictions on roads and bridges.

    Plan:Check postings on every leg before a spring move.

What we check before filing in Maine

  1. State Police escorts are booked ahead

    On Maine interstates only State Police escort a load 16 ft wide or 125 ft long. We request it at least three working days before the move.

  2. Maine's holiday list is longer

    14 holidays in 2026, including Patriot's Day, Juneteenth and the Friday after Thanksgiving, plus holiday weekends. We check your dates against all of them before filing.

  3. The 10-day window

    Most trip permits can't be obtained more than 10 days ahead. We file inside that window so the permit is ready on your move date.

FAQ

Maine oversize permit questions

Does Maine BMV or MaineDOT issue overlimit permits?

The Secretary of State's Bureau of Motor Vehicles issues them. MaineDOT advises the BMV on the route.

How much does a Maine oversize permit cost?

It depends on the permit type, size, weight and route; extreme loads need an engineering review. Put your route into our permit cost calculator for an estimate, or send us the load and our permit desk quotes the exact price before filing.

How far ahead can a Maine trip permit be issued?

Most can't be obtained more than 10 days before the move. The permit covers one direction from a set origin to a set destination within a designated period.

Is a separate permit needed for the Maine Turnpike?

Yes. The Turnpike issues its own permit, valid for one day, and none over 14 ft 6 in wide. Height stays at 13 ft 6 in there, with no extra 6 in of load.

When must Maine police escort an oversize load?

At 125 ft long or more, or 16 ft wide or more. On interstates the escort can only be Maine State Police, with three working days' notice.

Are Maine oversize moves allowed on summer weekends?

Saturdays until noon from April 22 to November 18, but only until 9 a.m. on I-95 from June 3 to August 26. Sunday moves in July and August need MaineDOT pre-clearance.

How does Route One GO get my Maine permit?

Send us the truck, trailer, load dimensions, axle weights and route. Our permit desk checks the Maine rules, files with the BMV and, if the route uses it, the Maine Turnpike, and sends you the permits. Requests are taken 24/7.
