What Is the I-70 Traction Law in Colorado?
From September 1 to May 31, all passenger vehicles traveling I-70 between Morrison and Dotsero must comply with the I-70 Traction Law. This law is designed to reduce accidents on icy, snow-packed roads in Colorado’s high country—especially during ski and snowboard season.
To comply, your vehicle must have:
- Tires with a minimum tread depth of 3/16 inches
- Tires labeled as snow tires or mud/snow (M+S)
- Or be equipped with four-wheel drive (4WD) or all-wheel drive (AWD)
Violations can cost drivers between $130 and $650 in fines.
Why 3/16-Inch Tire Tread Matters for Winter Driving
Your tire tread depth directly impacts traction on snow and ice. The legal minimum for standard tires is lower, but under the I-70 Traction Law, 3/16 inches is mandatory. Worn tires increase the risk of sliding, spinning out, or being unable to stop in sudden mountain traffic.
Whether you’re heading to Breckenridge, Vail, or Keystone, having compliant tires means safer travel for you, your passengers, and everyone on the road.
Winter Travel Safety for Skiing and Snowboarding
Colorado’s ski and snowboard trips are all about adventure—but the journey should be just as safe as the slopes are fun.
- Check your tires before every mountain trip
- Consider winter tires for maximum grip and performance
- Keep chains or traction devices in your trunk as a backup
- Inspect brakes, fluids, and windshield wipers for winter readiness
With heavy I-70 traffic during ski season weekends, being prepared can prevent delays, accidents, or worse.
