Arkansas Frost Laws & Spring Thaw Limits

Arkansas has no spring-thaw frost program. The climate does not freeze the sub-base deep enough to warrant a seasonal axle cut, so there is no percentage reduction and no annual thaw calendar. What can lower your legal weight is a posted route: ARDOT restricts individual roads by weight when pavement is failing and lifts them after inspection, and counties post their own bridges. That posted 'X ton' sign is the legal limit. Check ARDOT's restriction map and alerts.

No spring-thaw frost season. Arkansas runs no annual thaw program, though ARDOT can post individual routes for weight when pavement is failing, which is not tied to a frost calendar.
How much do the limits drop in Arkansas?
None from frost. On a pavement-restricted route ARDOT posts a specific weight limit for that road; obey the posted number, which is route-specific, not a statewide percentage.
