Mississippi Truck Bans & Hazmat Routes
Nothing exotic in Mississippi. No cars-only parkways, and no headline hazmat tunnel ban. Placarded loads default to the Interstates and follow the state's FMCSA-registered routes (49 CFR 397). The real limits are local: Jackson, Gulfport and Biloxi designate truck routes and post weight-limited streets, and a through truck with no local stop must stay on the network. Obey the posted clearance and weight plates. A bridge strike is your bill, not your GPS's.
A detail here is flagged medium confidence — confirm with the state DOT or the bridge/tunnel authority before you rely on it.

Key restrictions
- No parkway commercial bans and no notable hazmat tunnel ban
- Jackson posts truck routes and weight-limited streets by ordinance
- Placarded loads follow the Interstates and FMCSA-registered Mississippi routes
- Obey posted low-clearance and weight plates; a bridge strike is on you
- Parkway / road ban: No cars-only parkways and no truck-banned metro corridors. Truck limits are Jackson and Gulf Coast city truck-route ordinances and posted weight limits.
- Hazmat: No major hazmat tunnel or bridge ban. Placarded loads default to the Interstates and follow Mississippi's designated and preferred routes in the FMCSA registry under 49 CFR 397. Watch for locally posted hazmat and weight restrictions around Jackson and the Gulf Coast.
- Through-truck routes: Jackson and coast cities like Gulfport and Biloxi designate truck routes and post weight-limited and no-through-truck streets. A through truck stays on the route; a local truck leaves it only for the most direct path to its stop.
- Fine: A truck off a posted city route or over a posted weight limit draws a municipal fine, typically a misdemeanor citation; hazmat off a designated route adds state penalties. Amounts vary by city.
