Permits are valid for a stated route and for a limited period of time.
Maine, along with the States of Massachusetts, New Hampshire, Rhode Island and Vermont, is a member of the New England Transportation Consortium Overlimit Permit Program. Under this program, one state may issue an overlimit permit for an interstate move in two or more states. Vehicles exceeding these limits must obtain separate permits in each applicable state. Vehicles transporting overlimit loads are subject to certain safety, routing, time of day, and holiday restrictions, as well as escort requirements. A summary of the rule is below.
