Vehicle Classification Information
Vehicle classification is based on the height of the vehicle over the first two axles and the total number of axles, including any towed vehicles or trailers.
- LOW: Vehicles under 7 feet 6 inches in height are considered “LOW” (L).
- HIGH: Vehicles 7 feet 6 inches in height or greater are considered “HIGH” (H).
Total Number of Axles + Vehicle Height = Vehicle Class
