Wisconsin Oversize/Overweight Permit (6-WI-a)
Generally, a Permit is required if the developer’s vehicle and load exceeds:
- 8 ½ feet in width;
- 13 ½ feet in height;
- 75 feet in length; or
- 80,000 pounds in gross weight.
Oversize/Overweight Permit Process
6-WI-a.1 – Check WisDOT Weight Restriction Programs (Optional)
The developer may check WisDOT’s Weight Restrictions Programs Webpage to determine if there are any additional restrictions in effect prior to submitting a Permit application.
6-WI-a.2 – Oversize/Overweight Permit Application
The developer must complete and submit an Oversize/Overweight Permit Application (Application) to WisDOT. WisDOT has several different applications for different types of oversize and overweight loads. The type of load being transported determines which Application the developer should use. For example, if the load is a sealed container, the developer must submit a CS Application. The developer must determine which Application is needed. The Applications and load descriptions can be found on WisDOT’s Oversize/Overweight Application Forms Webpage.
The developer may submit the Application online, via mail, at the WisDOT Permit Office in Madison, or obtain the Permit through a Commercial Permit Service that conducts business with WisDOT. Wis. Admin. Code §Trans 254.03. WisDOT provides a List of Commercial Permit Services a developer may use to obtain a Permit. Some of these forms of submission may require an additional fee. The developer must also obtain insurance for the movement. The amount of insurance needed is determined by the specifications of the vehicle and load. Wis. Admin. Code §Trans 254.14.
The Application must include information relevant to the move, including:
- The developer’s name and contact information;
- The vehicle’s license plate and VIN numbers;
- The vehicle’s axle weights and spacing;
- The size and weight of the vehicle and load;
- A description of the contents of the load;
- The proposed move date(s); and
- The proposed route(s).
The developer must also submit the appropriate fee, determined by Wis. Stat. §348.25(8), with the Application.
6-WI-a.3 to 6-WI-a.4 – Review Application Materials for Completeness
After receiving an Application, WisDOT reviews the Application materials for administrative and technical completeness. If the Application is incomplete, WisDOT notifies the developer of the deficiencies.
6-WI-a.5 to 6-WI-a.7 – Review Application for Approval
After determining the Application is complete, WisDOT reviews the Application to ensure the method of movement and route are appropriate. WisDOT has thirty (30) days to either grant or deny the Application. Wis. Admin. Code §Trans 250.025. If WisDOT denies the Application, the developer should consider alternate routes or methods of transportation.
6-WI-a.8 – Oversize/Overweight Permit
If WisDOT approves the Application, WisDOT issues an Oversize or Overweight Permit to the developer. The Permit is valid for five (5) days after issuance. The Permit is subject to several general conditions, including those listed in Wis. Admin. Code §Trans 254, and WisDOT Single Trip Permit General Conditions. WisDOT may revoke the Permit if the developer violates the conditions of the Permit. Wis. Admin. Code §Trans 254.17.
