Texas Frost Laws & Spring Thaw Limits
Texas runs no spring-thaw frost program. The ground never freezes deep enough to soften the sub-base, so there is no seasonal axle cut and no percentage reduction (no statute exists for one). What can drop your legal weight: load-zoned roads, posted 'X ton' bridges, and short-notice emergency orders TxDOT issues after hurricanes or flooding (Tex. Transp. Code Ch. 621). The roadside sign is the limit. Check TxDOT Load Zoning and 511 Texas before you haul.
How Texas handles spring thaw
Texas runs no spring-thaw frost program. The ground never freezes deep enough to soften the sub-base, so there is no seasonal axle cut and no percentage reduction (no statute exists for one).

Window, reduction, and where to check
- Season: No seasonal spring-thaw restrictions. Texas ground does not freeze deep enough to thaw-weaken, so there is no frost-law window and no yearly dates to track.
- Reduction: None from frost. Weight can still be cut by load-zoned roads, posted bridges, and short-notice emergency orders after hurricanes or flooding, not by a seasonal percentage.
- Interstates: Exempt from the seasonal reduction
- Find the current order: There is no frost order to pull. For load-zoned roads and any temporary or emergency weight restrictions, check TxDOT's Load Zoning page and 511 Texas, and subscribe to TxDMV/TxDOT motor carrier email alerts.
- Overweight penalty: Standard overweight fine, set by pounds over the limit (Tex. Transp. Code 621.506): roughly $100-$500 up to 2,500 lb over, climbing to $7,000-$10,000 past 40,000 lb over.
