Oregon Chain Law & Traction Tires

Oregon posts a snow zone sign and the words on it are the requirement. Most of them ask a car to carry chains or traction tires rather than to fit them, which is why a driver can be legal on bare tires and still be fined for having nothing in the trunk.

What the snow zone signs require

A traction tire in Oregon is a studded tire, a retractable studded tire, or a tire carrying the three-peak mountain-snowflake emblem for severe snow service. A mud and snow (M+S) marking is not enough on its own — which is the trap if you have driven Colorado or Washington on the same set. Where chains are required on a car, they go on one tire on each side of the primary drive axle: the front tires on a front-wheel drive, the rear on a rear-wheel drive.

Carry chains or traction tires

They have to be in or on the vehicle. Nothing has to be fitted yet, and an empty trunk is the violation.

Chains required. Traction tires allowed on vehicles under 10,000 GVW

A car may run traction tires instead of chains — but only if it is not towing or being towed. Tow anything and it is chains.

Chains required on vehicles towing or over 10,000 GVW

A car that is not towing is unaffected. This level is aimed at trucks and trailers.

Conditional road closure

Posted when the standard restrictions are not enough for the conditions, and the wording on the day says who is exempt — ODOT's own example is chains on all vehicles except four-wheel drives that are not towing.

Fines

Non-compliance is a Class C traffic infraction.

Studded tires

Studded tires are legal in Oregon only from November 1 through March 31, and driving on them outside those dates carries a fine of nearly $200. Inside the season they do count as a traction tire. Oregon is the strict state on the other half of that list: Colorado and Washington both accept a plain mud and snow marking, and Oregon does not.

Commercial vehicles

Commercial vehicles are held to the higher standard: failing to carry and use chains is a Class A traffic violation, not a Class C, and the towing exception that lets a car use traction tires does not apply.

How you will know it is active

• Snow zone signs on the highway itself
• TripCheck.com, ODOT's own travel map, including its chain restriction layer
• ODOT road condition reports, per highway

Chain and traction tire requirements are ODOT's to post and they change with the storm. This page does not carry them — TripCheck ↗ is the authority before you set off.
