Colorado's Winter Driving Law

Posted On: 12/17/2019

Are you ready for Colorado’s new tire traction law on Interstate 70, the main road from Denver to Colorado’s ski resorts, including Vail, Aspen and Breckenridge?

From September 1 to May 31, the updated Colorado traction law requires drivers to have either tires with mud/ snow (M+S) designation, snow tires, or a four-wheel/ all-wheel drive vehicle. Also, all tires must have at least 3/16 of an inch tread or chains or an alternative traction device, like an AutoSock.

Questions? Have them answered because there are steep fines if you are involved in an incident that impacts traffic. Or, if you’d rather not worry about traction laws and tire tread depth, let Epic Mountain Express do the driving and arrive relaxed and ready to play in the mountains. Call our reservations agents or go online and book your ride today!

This flow chart from Colorado Department of Transportation (CDOT) breaks it down visually so you know if you are ready to drive I-70 to the mountain ski resorts.
