A developer must obtain a Permit if the developer’s vehicle and load exceed Mississippi size and weight restrictions. A vehicle is considered over-dimensional, in Mississippi, if the vehicle dimensions are in excess of the statutory limits set forth below:
- Width: Total width cannot be greater than eight and one-half (8-1/2) feet” Miss. Code Ann. § 63-5-13(1).

6-MS-a.3 to 6-MS-a.6 — Is the Vehicle Eligible for an ExpressPass Permit?
If the developer’s vehicle or load exceeds Mississippi’s size or weight restrictions, the developer may be eligible for MDOT’s ExpressPass Permit process, which allows companies to apply for, and be instantly issued, Oversize/Overweight Permits. MDOT provides information regarding the Oversize/Overweight ExpressPass on their ExpressPass Webpage. Generally, the ExpressPass Permit restricts movement during certain days and times. To be eligible for a 24- Hour Movement ExpressPass Permit, project developers must meet more stringent size and weight requirements. The overall size and weight limits for ExpressPass Permit eligibility are as follows:
- Maximum Gross Weight: 180,000 pounds (Daylight Movement Only)/150,000 pounds (24-Hour Movement);
- Maximum Height: 15 feet 6 inches (Daylight Movement Only) /13 feet 6 inches (24-Hour Movement)
- Maximum Width: 15 feet 0 inches (Daylight Movement Only) /12 feet 0 inches (24-Hour Movement)
- Maximum Length: 120 feet 0 inches (Daylight Movement)/ 4 feet 0 inches (24-Hour Movement).
MDOT automatically marks all permits that are eligible for 24-Hour Movement as "24-Hour Movement Authorized" upon issuance. To apply for an ExpressPass Permit, a project developer must:
- Download, sign, and fax the Mississippi Department of Transportation – Express Pass End-User Agreement to MDOT;
- Establish a valid MDOT charge account and submit proof of insurance to MDOT;
- Login to their ExpressPass account and select the applicable permit;
- Enter the following information where applicable: vehicle size and weight; travel origin, destination, and route; begin date of travel; and vehicle type, tag information, and load;

6-MS-a.7 to 6-MS-a.9 — Oversize/Overweight Permit Application

Miss. Code Ann. § 63-5-51(1)(b). Blanket Permits authorize the movement of loads less than 14 feet, are not term-limited, and require payment of a $100.00 annual fee. Temporary Trip Permits authorize load movement for no more than three (3) consecutive days. tit. 37-6601-03001 Miss. Code R. §§ 300.
