Oregon chain requirements for Mt. Hood confuse almost everyone the first time, including people who've lived in Portland for years. The signs use specific legal language, the rules change with a flip of a sign, and the fine for getting it wrong is real. Here's the plain-English version, plus where you'll actually be pulling over on the way to our cabin.
The three signs and what they mean
- "Carry Chains or Traction Tires." You must have chains in the vehicle, or be running traction tires. You don't have to put chains on yet. Most winter days on Highway 26 sit here.
- "Chains Required. Traction Tires Allowed on Vehicles Under 10,000 GVW." Passenger cars with traction tires can proceed without chaining. Everyone else chains up. Four-wheel and all-wheel drive vehicles get an exemption here if all of them tires are mud-and-snow rated (look for M+S on the sidewall) and you're carrying chains anyway.
- "Chains Required. Traction Tires Not Allowed." Everyone chains, including AWD and vehicles with studs. This is the rare, nasty-conditions sign. If you see it, the mountain is telling you something.

What counts as a traction tire
Studded tires, or tires marked with the mountain-snowflake symbol (the "three-peak" severe snow rating), or M+S tires under the AWD exemption above. Regular all-seasons without either mark don't count. Studs are legal in Oregon from November 1 through March 31; ODOT sometimes extends that. Chains must fit your tires; buy them before you're standing in a chain-up area in a snowstorm figuring out the size.
Does AWD mean I never chain?
No. The exemption for four-wheel and all-wheel drive requires M+S or better tires on all wheels, a vehicle under 10,000 pounds GVW, and that you're still carrying chains. And when the sign says traction tires not allowed, AWD chains up like everybody else. AWD helps you go. It doesn't help you stop or steer on ice, which is why the exemption has limits.
Where you'll actually chain up on Highway 26
Coming east from Sandy toward Wildwood Basecamp in Mt. Hood Village, you're at fairly low elevation and rarely need chains just to reach the cabin. The requirements kick in as you climb past Rhododendron toward Government Camp. Marked chain-up areas sit along the highway near Rhododendron and again closer to the summit. Pull fully off, put chains on the drive wheels (both, front and back for AWD when required), and drive under 30 mph with them on.
Timberline Road from Government Camp to the lodge is its own animal; it's steep and shaded and often carries a stricter requirement than the highway. Skibowl sits right in Government Camp and is easier. Details in ski cabins near Timberline and Skibowl.
Sno-Park permits are separate
Parking at Timberline, Skibowl, Trillium Lake, and other winter lots from November 1 through April 30 requires an Oregon Sno-Park permit on the dash. Day, three-day, and season permits are sold at DMV offices and many shops in Sandy and Welches. Chains get you up the hill; the permit keeps you from a parking ticket once you're there.
The realistic winter kit
- Chains that fit, practiced once in your driveway. Seriously, once.
- Gloves, a headlamp, a tarp or mat to kneel on.
- A small shovel and an ice scraper.
- Blanket, water, snacks. Highway 26 does close for crashes.
- A full tank. Gas in Government Camp is limited.
The honest part
Most winter weekends, a careful driver with good tires reaches Mt. Hood Village without touching the chains. The rules exist for the other days, and those days arrive fast. Our cabin sits low enough that you can wait out a storm in the hot tub and drive up to the ski areas when the plows are ahead of you. If you're comparing what's available in the area, see our Mt. Hood rentals.
Carry the chains. Know the signs. Let the mountain make the call.
