Sufficient tire chains are defined by the Washington State Department of Transportation (WSDOT) as follows:

All vehicles over 10,000 pounds GVW shall carry a minimum of 2 extra chains for use in the event that road conditions require the use of more chains or that chains in use are broken or otherwise made useless, WAC 204-24-050 (2) (f).

Approved chains for vehicles over 10,000 pounds gross vehicle weight shall have at least two side chains attached sufficient cross chains of hardened metal so that at least one cross-chain is in contact with the road surface at all times. Plastic chains shall not be allowed. The Washington State Patrol may approve other devices as chains if the devices are equivalent to regular chains in performance (cable chains allowable).

Vehicles making local deliveries as indicated on bills of lading and not crossing the mountain pass are exempt from this requirement if operating outside of the chain required area, WSDOT states.
