Oversize / Overweight Vehicle Permits

The Oversize / Overweight (OS/OW) Permit Office within the Bureau of Highway Operations ensures the safe and efficient movement of traffic over the State highway network, protects the motoring public and ensures safe preservation of the State's infrastructure. The OS/OW Permit Office issues permits to owners or operators of non-conforming vehicles travelling on the state and local roadway networks. These vehicular permits limit the routes, times of operations, maximum rate of speed and other conditions deemed necessary by the State. This website provides general information and guidance pertaining to the issuance of OS/OW permits.
