Snowy weather and bitter cold temperatures expected, particularly in the high-country

It’s the calm (and warm weather) before the storm. The Colorado Department of Transportation has issued a warning for motorists to expect a return of winter weather this weekend. A major storm system is expected to move across the Colorado Rockies Saturday through Monday, bringing the potential for moderate to heavy snow accumulations to the Continental Divide.

According to the National Weather Service, travel impacts due to slick roads could be greatest across central, western, and southern Colorado and the San Juan Mountains on Saturday and Sunday. Snow is also expected across eastern Colorado Saturday night.

Travelers must be prepared for winter driving conditions. If you live here, you know what to do. For those flat-landers not used to snow, or for that matter, mountain driving — be careful. Your trip begins with planning. Check the weather and road conditions by going to before heading out.

Make sure you are equipped for the drive. Tires with at least 3/16″ of an inch of tread are essential. A well-maintained vehicle and an emergency kit with extra clothing, water, food, and other essentials are critical to mountain driving in the winter.

Once you are out on the road, take it slow, avoid sudden stops, and leave plenty of following distance. Give plows space! Give Colorado State Patrol and emergency vehicles space. Stay back three to four car lengths from snowplows. Should the weather get severe, there is the possibility of road closures.

The Colorado Department of Transportation will have road crews out in advance of and throughout the winter storms to clear and treat roads.

Chain and Traction Laws 
When weather conditions warrant, CDOT will activate the Traction Law. If weather conditions deteriorate, CDOT will activate Chain Laws for passenger and commercial vehicles.

Motorists will be alerted to an active Traction or Chain Law by highway signage, and traffic/roadway condition alerts.

For more information on the Traction Law and Passenger Vehicle Chain Law requirements, visit For more information on the Commercial Vehicle Chain Law requirements, visit To learn more and view helpful tips for winter driving, visit and COtrip Planner app
Motorists are urged to visit and download the COtrip Planner app ahead of traveling. Motorists are now able to sign up for travel alerts through to see if there are any highway closures or impacts along their favorite routes. The COtrip Planner app also offers a “Trip Planner” feature that allows motorists to map out their routes and receive updates about road closures or incidents along the way. Motorists can turn on the “Hands-Free, Eyes Free” feature to receive these alerts via voice notifications and avoid routes with impacts.

CDOT is offering motorists the opportunity to track CDOT snow plows on the app and website, and can even follow some of the CDOT “celebrity” plows that were named by elementary school students last year. Using the snow plow tracker allows motorists to see where our plows have been and even see what the road conditions look like by viewing the cameras in the area of the plows.

CDOT plows have thousands of miles of roadway to maintain, so motorists are asked to please be patient and are reminded to never pass a plow on the right or while in echelon formation. It is always safer to stay behind a plow.
