Tire chain installation

WSDOT issues permits allowing businesses and individuals to install and remove motorist-owned tire chains

WSDOT issues permits allowing businesses and individuals to install and remove motorist-owned tire chains.

How does it work?

WSDOT notifies chain installers when chains are required. They are not required to respond so all drivers should be able to install their own tire chains.

If chain installers are working, drivers pull into locations signed on I-90.

Chain installers cannot sell tire chains and are required to display a WSDOT permit.
