Maine Oversize Load Signs, Flags And Lights

What Does Maine Specify For The Load Signs?

The BMV summary specifies OVERSIZE LOAD, black letters 10 inches tall on yellow, on a sign 7 feet wide and 18 inches high. It calls for signs front and rear, removed or covered when the vehicle is no longer oversize.

Inspect the installed rear sign after tarps, chains and cargo are in place. A folded banner in the cab does not provide a warning to the driver approaching the load. Plan the change back to a legal-size return trip at unloading, rather than leaving the signs displayed by habit.

Where Do Flags And Cab Lights Fit?

The summary lists four red or fluorescent-orange flags, each 18 inches square, at the extreme corners. It separately lists low-beam headlights and flashing, rotary or light-bar amber equipment on top of the cab. The special amber lighting is extinguished when the vehicle is not oversized.

Assign the walk-around by vehicle and corner. If the load blocks an attachment point, resolve the mounting before starting the move. Include the electrical supply and switch in the check; owning the right light does not establish that it is operating.

What Changes For A Maine Pilot Car?

For a pilot vehicle, the BMV summary gives a 5-foot by 12-inch sign with 8-inch black letters on yellow. Its front or rear location follows whether the pilot leads or follows; a suitably facing roof mounting is also described.

A relief escort should receive the role and intended mounting arrangement during handoff. Do not assume the car is ready because it escorted the same truck in a neighboring state. The BMV summary explicitly points drivers to the full pilot-vehicle rules.

Does The Same Checklist Apply To Mobile Homes And The Turnpike?

Maine’s summary lists additional rear lighting for mobile or modular units at least 13 feet 6 inches wide. It also distinguishes Maine Turnpike authority from BMV authority and local-road permission.

Treat the planned road and cargo category as inputs to the equipment review. For example, a modular unit leaving a Turnpike interchange still needs a check of the state and local legs; a toll-road transaction is not a complete departure briefing for the remaining roads.

How Can RouteAll Help Prepare This State Leg?

Import the issued Maine permit into RouteAll, review the extracted roads against the document and share the reviewed route with the crew. Use the permit packet to check marking conditions separately. RouteAll does not inspect warning equipment or certify compliance; a route shown in the app does not approve signs, flags or lamps.

Before You Roll

Check both truck sign faces, each corner flag, the operating cab light and the escort’s role. Confirm any extra cargo-category and Turnpike conditions.
