OREGON/ CALIFORNIA --- There are chain requirements in Oregon and California.
Chains are required on parts of Diamond Lake Summit. If you are heading west you have to have chains on from milepost 0-23. If you are heading east it's from milepost 83-93. There is packed snow on the ground. Traction tires are allowed instead of chains.
Chain requirements on I-5 have been lifted. Traffic is moving slowly.
This list will be updated as requirements change.
