Louisiana Frost Laws & Spring Thaw Limits
Louisiana has no spring-thaw frost law. Deep-South winters never freeze the roadbed enough to thaw-weaken it, so the state declares no seasonal weight order and cuts no percentage off your axles. Your legal weight can still drop on posted parish and local roads and at weight-restricted bridges, where the posted 'X ton' sign is the limit even if no state map flags it. No seasonal order to pull, but check DOTD and watch for posted signs.

Window, reduction, and where to check
- Season: No seasonal spring-thaw restrictions. Louisiana has no frost-law program and no yearly window to track.
- Reduction: None from frost. Weight is still capped by posted parish and local roads and weight-restricted bridges, not by a seasonal percentage cut.
- Interstates: Exempt from the seasonal reduction
- Find the current order: No frost order exists. For posted bridges and route limits, check DOTD (Louisiana Department of Transportation and Development) and obey posted 'X ton' signs on parish and local roads.
- Overweight penalty: Standard overweight fine, assessed per pound over the legal or permitted limit under Louisiana motor carrier law (La. R.S. 32:388), plus a failure-to-stop-at-scale penalty. Confirm the current schedule with DOTD.
