Florida Truck Weight Limits
Complete guide to commercial vehicle weight regulations in Florida, including axle limits, permit requirements, and seasonal restrictions.
Weight Limits
| Axle Type | Florida Limit | Federal Limit | Difference |
|---|---|---|---|
| Single Axle | 20,000 lbs | 20,000 lbs | 0 lbs |
| Tandem Axle | 34,000 lbs | 34,000 lbs | 0 lbs |
| Gross Vehicle Weight | 80,000 lbs | 80,000 lbs | 0 lbs |
| Steer Axle (min) | 12,000 lbs | 12,000 lbs | 0 lbs |
| Steer Axle (max) | 20,000 lbs | 20,000 lbs | 0 lbs |
Florida has source-verified table, spacing, route, permit, or vehicle-specific rules. The calculator applies verified base limits and implemented contexts, but exact special-case output still needs source-chart fixtures.
Showing interstate route, standard operation.
Enforcement tolerance: 10% on axle weight.
Bridge Formula
Florida uses the standard Federal Bridge Formula to calculate maximum weight on groups of consecutive axles.
- W = Maximum weight (lbs)
- L = Distance between outer axles (ft)
- N = Number of axles in the group

Values reflect FHWA policy of rounding down when calculated weights fall exactly halfway between 500-pound increments.
Florida allows a 10% enforcement tolerance on axle weight.
Florida has source-verified table, spacing, route, permit, or vehicle-specific rules. The calculator applies verified base limits and implemented contexts, but exact special-case output still needs source-chart fixtures.
Always verify current regulations with Florida DOT before making shipping decisions.
