Dray Overweight
How it works

How Dray Overweight Works.

From load submission to permit delivery in under 60 seconds. Five steps, fully automated.

Auto Compliance Check

The engine evaluates 38 compliance inputs in real time — federal axle limits, state-specific weight thresholds, bridge formula groups, width and height restrictions, and current permit requirements.

Route Cleared

A bridge-safe route is calculated and pushed to the driver's navigation. The route avoids low bridges, weight-restricted roads, and seasonal closure zones based on current state data.

Compliant Move

Real-time monitoring tracks the load from yard to delivery. Compliance status updates automatically if a state changes a limit mid-trip. Delivery confirmation closes the permit and logs the move.
