SNOW ZONE LAWS ARE IN EFFECT!! They apply to residents and non residents alike, without exceptions. From now through March 31st, you must carry chains or have approved traction tires or studs on regardless of vehicle type in Oregon in areas designated snow zones. In Southern Oregon that is ALL areas of the Cascades above 3000 feet, and also ALL areas east of the Cascades regardless of elevation point. West of the Cascades, Snow Zones are designated with signage where applicable. This can be any elevation point with incline gradients to the road involved. You are encouraged to have chains with you regardless of vehicle type and if you have approved snow tires or studs on. In times of heavy snowfalls, traction tires alone will not suffice. And, if you are towing you will always have to chain up. ALWAYS!

In Northern California, Snow Zones are designated with signage. However, carry chains will only be the law when winter weather conditions are occurring or are expected to occur. As is the case with Oregon, approved traction tires or studs will typically get you by. But! They do require chains to be with any vehicle at any time if the conditions call for it. They will screen your vehicle to be sure you have them. Therefore.....ALL vehicles must carry chains in California regardless of type. And, in California it is not uncommon for chain requirements to include 4 wheel / all wheel drive vehicles.        

If you have not put your studded tires on yet, you will want to do that now. Snow, with packed snow on road surfaces, can be expected at any time above 4000 feet in Southern Oregon and Northern California through at least late March. Many highly traveled routes including Siskiyou Summit on I 5 are above 4000 feet. ALL passes through the Cascades in Southern Oregon and Northern California are above 4000 feet.
