Arkansas Truck Bans & Hazmat Routes
No cars-only parkways in Arkansas. Your metro rule is Little Rock's hazmat loop: I-630 end to end, plus the downtown stretch of I-30 between I-440 and I-40, are closed to placarded loads, so you swing around on the I-440 bypass (FMCSA AR registry, 49 CFR 397). I-40 stays open and, with I-30 south of I-440, carries route-controlled radioactive freight. Little Rock and Fort Smith post their own truck routes and weight-limited streets; a through truck stays on the network, a local delivery leaves it only for the stop.

Key restrictions
- Hazmat restricted on I-630 (entire) plus downtown I-30 from I-440 to I-40 in Little Rock; use the I-440 bypass
- I-40 is NOT restricted; it and I-30 south of I-440 are the preferred routes for route-controlled radioactive loads
- No parkway commercial bans; obey posted city truck routes and weight limits
- Follow FMCSA-registered Arkansas designated and preferred routes for placarded loads
- Parkway / road ban: No cars-only parkways. Truck limits come from Little Rock and Fort Smith truck-route ordinances and posted weight-limited streets, not parkway law.
- Hazmat: Little Rock closes part of its downtown Interstate loop to placarded hazmat: I-630 for its whole length, plus the downtown stretch of I-30 between I-440 and I-40, are restricted (local-delivery exception), so hazmat takes the I-440 eastern bypass. I-40 stays open; it and I-30 south of I-440 (toward Texarkana) are the preferred routes for highway-route-controlled radioactive loads under 49 CFR 397.
- Through-truck routes: Little Rock, Fort Smith and other cities designate truck routes and post no-through-truck and weight-limited streets. A through truck with no local stop stays on the route; a local delivery takes the most direct path off it and back.
- Fine: Taking a placarded load onto a restricted Little Rock Interstate, or a truck off a posted route, is a violation carrying a municipal fine plus state hazmat penalties. Amounts vary by citation.
