For anyone asking themselves whether I wrote about this last year, the answer is yes, I did.  Nonetheless, a reminder about a recurring, annual safety issue can't hurt. The Stark Family's oft-repeated words (yes, I know Game of Thrones ended forever ago) will soon be ringing true - “winter is coming.”  When it arrives we may have one of our occasional winter storms that dumps significant snow, or we may go the mountains to find it at ski resorts, mountain retreats, or snow parks. 

Being prepared for winter driving is essential. Many an auto accident or stranding has been occasioned by snowy or icy roads.  But in many areas, having your car properly outfitted for winter driving is more than just good sense- it's the law.

Highway Signs Showing Chains Requires

Many Southwest Washington residents heading into winter driving conditions are doing so in the Oregon Cascades. In Oregon, highway signs will tell drivers when chains or other traction devices are required on a stretch of road. If you're using tire chains, carry them with you in the vehicle at all times.

Traction Tires

For those not wanting to fuss with tire chains, traction tires may be used on vehicles rated at 10,000 lbs. gross vehicle weight (GVW) or less, and not being towed or towing anything. “Traction tires” are defined as studded tires, or ones specially designed for winter driving, which bear this logo:

Studded Tires

Studded tires are legal in Oregon (and Washington) Nov. 1 through Mar. 31, but are discouraged due to the damage they cause to roadways. Failure to follow the rules means you might receive a citation, including for merely not carrying chains in your vehicle in a snow zone. 

In Washington, if signs say chains are required, studded tires will not suffice to comply with the law, but having traction tires will bring you into compliance. You must still carry chains, even with traction tires, in the worst areas (usually mountain passes). Washington's winter driving requirements can be checked.
