Section 250-157-19 - MAINE TURNPIKE AUTHORITY1. Travel on the Maine Turnpike is governed by Rules and Regulations adopted by the Maine Turnpike Authority, including but not limited to rules with respect to size and weight limitations. There also are restrictions on time of travel and some overlimit vehicles may be allowed to move at night. The Maine Turnpike may require pilot vehicles and State Police escorts at lesser dimensions and weights than required by this rule.2. Overlimit loads are not allowed on the Maine Turnpike when speeds are reduced to 45 miles per hour. If an overlimit load is on the Turnpike when speeds are reduced, the vehicle must exit the Turnpike at the earliest possible point, and await the return to normal posted speeds.3. Many bridge clearances on the Maine Turnpike are at 13 feet 6 inches.4. The Secretary's issuance of a permit listing the Maine Turnpike as a route does not relieve the permittee of the obligation to also obtain a Turnpike-issued permit. The Turnpike requires a permit fee in addition to the fare normally charged for the class of vehicle involved.29- 250 C.M.R. ch. 157, § 19
