Statewide — Earlier today, CDOT, the Colorado State Patrol, the I-70 Coalition, AAA Colorado, AutoSock and Peerless Tires welcomed Coloradans to its Winter Wise Village, providing the community with resources to stay safe and prepared for winter driving conditions — including free tire checks, discounts on snow tires and Traction Law and safety information.

“Winter weather is unpredictable in Colorado, and the best way to stay safe is to always be prepared for the weather to turn,” said Andrew Hogle, CDOT communications manager. “With the support of our partners, we are able to offer Coloradans a wide range of resources to stay safe this winter.”

In 2021, roughly 12.6 million drivers traveled through the Eisenhower-Johnson Memorial Tunnels, marking an 11% increase compared to the 11.3 million travelers in 2020. To date, there have been 10.7 million travelers in 2022, showing an increasing trend from previous years.

As director of the I-70 Coalition, Margaret Bowes knows that congestion on the I-70 mountain corridor during the winter can lead to extended delays and pileup crashes. Carpooling options can be found on for Coloradans without a car or who are not crazy about winter driving.

“Congestion on the I-70 mountain corridor is nothing new, but we want to remind drivers that avoiding peak travel times will reduce traffic on the corridor,” said Bowes. “If your vehicle is not well equipped to travel in winter conditions, there are plenty of alternative options like transit and carpooling. Reducing vehicles on the road will lead to quicker travel times and an overall safer travel experience for drivers.”

Colorado’s Passenger Vehicle Traction Law requires that all motorists have 3/16” tire tread depth and an all-wheel or four-wheel drive vehicle, winter tires (mountain-snowflake icon), tires with an all-weather rating, or mud/snow tires (M+S icon). If a vehicle has neither all-wheel, four-wheel drive or the adequate tires mentioned above, it must have chains or an approved alternative traction device.

“Traction Law awareness and compliance makes a world of difference as we try to make Colorado winter roads safer,” said Master Trooper Gary Cutler of the Colorado State Patrol. “Driving slowly and ensuring you have space to stop behind the car in front of you is also crucial. The combination of adequate tire tread and slower speeds will lead to more Coloradans getting home safely this winter.”

CDOT offers the following tips and reminders to help drivers be safe this winter:

  • Know the Traction Law requirements. If you plan to drive on the I-70 mountain corridor any time from Sept. 1 to May 31 between Dotsero and Morrison, you must have 3/16” tire tread depth and one of the following:
    • 4WD or AWD vehicle
    • Winter tires (mountain-snowflake icon)
    • Tires with an all-weather rating by the manufacturer
    • Tires with a mud/snow designation (M+S icon)
    • Chains or an approved alternative traction device
  • Avoid traveling during peak times. offers weekend travel forecasts that are updated every Thursday afternoon to help you plan
  • Use safe public transit if you need a ride. Bustang, Pegasus, Snowstang offer service to and from certain mountain areas, and Bustang Outrider offers service in rural regions. Visit for multiple transit options along the I-70 mountain corridor
  • Be patient during safety metering. If you are stopped on I-70 near the Eisenhower Tunnel, it may be due to safety metering. Safety metering helps control traffic flow, reduce accidents and keep the tunnel clear for emergency vehicles to get through. Please be patient
  • Express Lanes are available. There are I-70 Mountain Express Lanes in both directions of I-70 adjacent to the free, general-purpose lanes between the Veterans Memorial Tunnels and Empire interchange. These Express Lanes operate during peak travel times. To learn more, visit
