Obtaining a Mississippi Oversize Permit
Mississippi provides several types of permits to accommodate different needs:
- Single Trip Permit: This permit allows a vehicle or load to make a one-way trip within Mississippi. It’s ideal for occasional or infrequent oversize hauls.
- Annual Permit: Valid for up to one year, this permit allows multiple trips within Mississippi during its duration. It’s perfect for frequent haulers who regularly transport oversize loads that exceed standard size and weight limits.
- Trip and Fuel Permits: These permits are required for vehicles not registered in Mississippi but that need to travel through or conduct business in the state temporarily. They cover both oversize and overweight loads, as well as fuel usage.
- Superload Permit: For exceptionally large or heavy loads that go beyond standard oversize limits, a superload permit is necessary. These permits are issued on a case-by-case basis, involving additional scrutiny and special considerations due to the load’s extreme size or weight.
