Restriction Information

Traction Law (Code 15)

During an active Traction Law (also known as a Code 15), motorists must have either snow tires, tires with the mud/snow (M+S) designation, or a four-wheel/all-wheel drive vehicle.

Starting Aug. 2, 2019, the legislation updated requirements for drivers using state highways during winter months. Specifically, it changed the required minimum tire tread for vehicles on snowy roads to 3/16 of an inch. The statute also says that the minimum tire tread for dry roads is 3/16 of an inch. You can also install chains or an alternative traction device (like AutoSock) to be in compliance with the law if your tires aren't adequate.

Passenger Vehicle Chain Law (Code 16)

During severe winter storms, CDOT will implement a Passenger Vehicle Chain Law (also known as a Code 16). This is the final safety measure before the highway is closed.

When the Passenger Vehicle Chain Law is in effect, every vehicle on the roadway must have chains or an alternative traction device (like AutoSock).

Fines

Motorists driving with inadequate equipment when a Passenger Vehicle Traction Law or Chain Law is in effect could be fined more than $130.

If a motorist blocks the roadway because he/she has inadequate equipment when a Passenger Vehicle Traction Law or Chain Law is in effect, he/she could be fined more than $650.

Commercial Restrictions

Truckers are required to carry chains from September 1st to May 31st between Dotsero and Morrison.

Please refer to CDOT regarding chain laws and additional information.
