I can’t use regular cable chains because there’s not enough clearance in the wheel well. What other approved traction devices can I use?
It is recommended you consult the vehicle owner’s manual to see what the manufacturer suggests. The following alternative traction devices are certified by their manufacturer as meeting or exceeding chain requirements in accordance with WAC 204-24-035 and are therefore considered approved for use when “Chains Required” signs are posted:
- For passenger cars the following alternative traction device is approved:
- For Vehicles or vehicle combinations over 10,000 pounds:
- With five or less axles: Autosock
- With six or more axles: No alternative traction device has been certified by a manufacturer as meeting the requirements for approval.
