Oversize Load Information and Permits

The Authority for Municipalities to Enact Regulations for Movement of Oversize/Overweight Loads is granted through RCW 46.44.090

Permits are required when any vehicle, vehicle combination, and/or equipment or machinery being moved exceeds the dimensional and/or weight limits set forth in RCW 46.44.

A City of Tacoma permit is required only for movements that are point-to-point within City limits.

State of Washington oversize permits are accepted when movement of a load originates or terminates outside City limits.

Over dimensional loads are prohibited from moving on City streets during commute hours.


Statement Regarding Oversized Vehicles


Due to ongoing construction throughout the City, to include the port areas, any oversized load requiring the use of escort vehicles must contact the Road Compliance Department seven (7) days prior to the move date so the necessary arrangement may be made.


Failing to do do may result in the load getting turned away.
