Florida Truck Bans & Hazmat Routes

Where Florida keeps trucks out

Florida has no cars-only parkways; the Turnpike and toll roads take trucks. The hazmat catch is the Port Miami Tunnel under Biscayne Bay. It bans placarded hazmat and oversize loads, which move to the port by rail instead, and it clears 15 feet. That tunnel is the designated truck route into PortMiami, built to pull trucks off downtown streets. Jacksonville and Tampa post freight corridors and port routing with time-of-day limits. Otherwise follow 49 CFR 397.

Key restrictions

• Port Miami Tunnel: no placarded hazmat, no oversize (they move by rail); 15 ft clearance.
• The tunnel is the designated route into PortMiami, keeping trucks off downtown streets.
• Jacksonville and Tampa: designated freight corridors and port routing with time-of-day limits.
• No cars-only parkways; hazmat follows 49 CFR 397 designated routes.

• Parkway / road ban: No cars-only parkways; the Turnpike and toll roads carry trucks. Miami's Port Miami Tunnel bans placarded hazmat and oversize loads and is the designated truck route into the port.
• Hazmat: The Port Miami Tunnel under Biscayne Bay bans placarded hazmat and oversize loads, which reach PortMiami by rail instead; it clears 15 ft. That tunnel is the designated truck route into the port, built to pull trucks off downtown Miami streets. Elsewhere Florida has no state-specific tunnel or bridge hazmat ban; placarded loads follow 49 CFR 397 designated routes and stay off tunnels, crowded streets, and alleys.
• Through-truck routes: Jacksonville and Tampa post designated freight corridors and port routing, with time-of-day limits near downtown and the ports. Local 'no thru truck' streets exist; a local delivery may leave the route by the most direct path. STAA reasonable access applies statewide.
• Fine: A hazmat routing or posted-restriction violation is handled under Florida's uniform traffic law (Fla. Stat. Ch. 316) as a citation; a placarded load off its required route also risks FMCSA/PHMSA civil penalties in the thousands. A tunnel or low-bridge strike is the driver's bill.
