Delaware Truck Bans & Hazmat Routes

Where Delaware keeps trucks out

Delaware is light on truck bans. There is no cars-only parkway and no highway tunnel, so no propane-in-the-tunnel trap here. The Delaware Memorial Bridge stays open to trucks, though the bridge authority pulls campers and high-profile rigs in strong winds. Placarded loads follow federal preferred routes on the I-95 corridor (49 CFR 397). Your real job is reading DelDOT's posted low-clearance and load-posted bridges around Wilmington.

Key restrictions

• No highway tunnel and no cars-only parkway; standard truck-route rules apply.
• Delaware Memorial Bridge: open to trucks, but high-profile vehicles get pulled in strong winds.
• Check the DelDOT bridge-restrictions map for posted low clearances and load-posted bridges around Wilmington.

• Parkway / road ban: No cars-only parkway ban and no highway tunnel. The Delaware Memorial Bridge (I-295/US 40) is open to trucks, with high-wind restrictions on high-profile vehicles. Watch DelDOT-posted low bridges instead.
• Hazmat: No state tunnel hazmat ban; Delaware has no highway tunnel. Placarded loads on the I-95 corridor through Wilmington and over the Delaware Memorial Bridge follow FMCSA-designated and preferred routes under 49 CFR 397. In high winds the bridge authority may restrict campers, tractor-trailers, and other high-profile vehicles.
• Through-truck routes: STAA rigs run the National Network and DelDOT-designated routes. Wilmington posts through-truck bans and weight-limited streets. Use the DelDOT bridge-restriction map for posted height and load limits before you leave the Interstate.
• Fine: A through-truck or posted-route violation is a state citation, commonly a fine in the low hundreds set by the court, plus damage liability if you strike a posted low bridge. Exact figures vary; confirm with DelDOT.
