A slow-moving storm will impact travel statewide starting Wednesday night into Thursday. The Colorado Department of Transportation (CDOT) is warning motorists that winter storm conditions have been are expected through Thursday.  

The National Weather Service (NWS) predicts heavy snow will develop over Utah and the Four Corners region, with snow spreading over the mountains late overnight, and then over the eastern plains by early Thursday morning between 3:00 and 4:00 a.m.  The potential snow accumulation on the northern mountains (Berthoud Pass and Loveland Pass) has also prompted the Colorado Avalanche Information Center (CAIC) to caution high country motorists of likely snow slide mitigation along mountain pass corridors. The avalanche control work will cause travel delays while operations are taking place and plows then clear the roads.

"This time of year, we have a lot more people on our roads due to the holidays," said Kyle Lester, CDOT Director of Highway Maintenance. "Our snowplow operators will be out in full force pretreating our roads before the storm and they'll be out there until the system moves out of the area using their deicing products and plow blades. We ask the public to join us in making the roads safe by being prepared for winter driving before getting behind the wheel."

CDOT is offering the following list of tips and guidelines for Colorado drivers to be winter ready:

  • Check your tires
    • Worn tires can't grip the road well and can be extremely hazardous. Check your tires by performing the Quarter Test. Insert a quarter into the tire tread upside down, with Washington's head going in first; if the top of George's head is covered by the tread, your tires are OK (do this test in multiple points around each tire). If the top of his head is visible at any point, you need new tires.
    • Invest in safety by getting a set of snow tires. When it comes to stopping safely on snow and ice, all-season tires simply don't compare to winter tires (see infographic).
    • If your tires don't have at least a one-eighth inch tread when a Traction Law is called, you are in violation of the law and could end up with a fine.
  • Leave extra room
    • Leave extra room between your vehicle and others on the road at all times.
    • Even vehicles with four-wheel/all-wheel drive will not stop any quicker on icy roads, especially if you have inadequate tires.
  • Drive for conditions
    • In poor visibility, don't drive faster than you can see ahead. High speeds in poor visibility can lead to dangerous chain reactions.
  • Bow to the plow
    • Snow plows need space to work, so unless you want to cause a crash, delays or be stuck on a snow-covered road, don't crowd the plow!
    • If you must pass a snowplow, do so on the left and with extreme caution.
  • Be I-70 smart
    • Check Goi70.com to see travel forecasts for the I-70 mountain corridor, road updates, rideshare and parking information, deals on lodging, food and entertainment for travelers and more.
    • Remember to avoid peak travel times whenever possible and consider carpooling or alternative transportation.
  • Have a plan
    • If you are stuck in a serious storm, do not leave your car. Run the engine periodically and wait for help.
    • Prepare a winter driving vehicle kit. Carry blankets, water, a flashlight, a shovel, some nutrition bars or other food for sustenance. Winterize your vehicle's safety kit by including extra blankets, sand to help gain traction in the event you become stuck on ice or snow, jumper cables and an ice scraper.

 

Additionally, all motorists should be familiar with Colorado's Passenger Vehicle Traction Law and Passenger Vehicle Chain Law. These laws are implemented when weather and road conditions require it, at which time highway signage will be activated to alert drivers.

  • Traction Law -- When the Traction Law is in effect, motorists must have snow tires, tires with mud/snow (M/S) designation, or a four-wheel/all-wheel drive vehicle -- all tires must have a minimum one-eighth inch tread.
  • Passenger Vehicle Chain Law -- Reserved for severe winter conditions as the final safety measure before an interstate is closed, the Passenger Vehicle Chain Law states that every vehicle on the roadway must have chains or an alternative traction device (like AutoSock).

Without proper equipment, you can be fined $130. If your vehicle blocks the roadway, you could be fined more than $650.

Weather Impacts: Regionally throughout the state, motorists can expect the weather to impact travel.

Front Range/Metro Denver (Region 1)

Roads will be icy and snowpacked by tomorrow morning's commute with the most intense part of the storm likely hitting between 3 and 5 a.m. Motorists should be cautious while driving over bridges, overpasses and ramps as these areas generally produce icier conditions. Crews in the metro area went on snow shift at 3 p.m. and have been applying anti-icing product since this morning, motorists will likely see white stripes on the roadway as a result. Travelers should plan ahead for potential delays and a slower commute.

Southeast (Region 2)

The forecast for southeastern Colorado is not calling for heavy accumulation, however temperatures are expected to dip below freezing. Icy slick conditions could exist on several roadways throughout the region, particularly Monument and Raton Passes. CDOT crews in the region will be on snow shift and applying pre-treatment where appropriate. Travelers should plan ahead for potential delays and slower commutes.

Northwest (Region 3)

Forecasters are calling for heavier snowfall to impact the higher elevations in Northwest Colorado starting after midnight tonight. CDOT crews are on 24-hour snow shifts and will be pre-treating highways from Glenwood Springs and east on the I-70 corridor.  The Thursday morning commute throughout the region could be affected by icy roads with slightly reduced visibility due to snow and wind.

Northeast (Region 4)

Motorists should expect icy and snowpacked conditions from I-25 Denver North to Wyoming Border and snowfall accumulation of one to four inches. The eastern plains will see a trace amount of snow but will have winds between 20 to 35 mph with blowing and drifting snow. Crews are on 24-hour snow shift and will be pre-treating the roads and will continue with deicing products as the storm intensifies.    

Southwest & South-Central Colorado (Region 5)

Starting Thursday night through early Friday morning, motorists can expect difficult driving conditions, especially along high country mountain passes (CO 145 Lizard Head; CO 62 Dallas Divide, US 550 Red Mountain, Molas and Coal Bank; US 160 Wolf Creek and La Veta; CO 17 La Manga/Cumbres; US 50 Monarch; and US 285 Poncha and Trout Creek). Snow and high winds may cause drifts and blowing snow with limited visibility of the roadways. Friday morning commuters should allow themselves more time for travel.

"With many driving in from out of state or for those who are feeling stressed with the holidays, we ask that you be aware if you are feeling drowsy and if you are, pull over and take some time to refresh and wake up before hitting the roads again," said Lester. "The best way to drive in the snow is to be alert, travel at slower speeds, and know the road conditions before you go."
