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.
How Arkansas handles spring thaw
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.

Window, reduction, and where to check
- Season: 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.
- Reduction: 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.
- Interstates: Exempt from the seasonal reduction
- Find the current order: No seasonal frost order to pull. Check ARDOT's (Arkansas Department of Transportation) weight-restriction map and news releases for individual posted routes, sign up for ARDOT email alerts, and obey posted 'X ton' signs.
- Overweight penalty: Overweight is a misdemeanor fined by pounds over the limit (Ark. Code 27-35-202), escalating for repeat offenses within a year, and willfully bypassing a weigh station doubles the penalty. Confirm current amounts with the Arkansas Highway Police.
