Denver, CO – A mountain highway that looks perfectly safe could conceal a dangerous surprise for Colorado drivers. One of winter's most deceptive roadway hazards can develop overnight, leaving motorists facing slippery pavement that may offer little warning before their vehicles begin sliding out of control.
According to the National Weather Service, black ice can form when rain, melting snow or lingering roadway moisture freezes, creating a thin, nearly transparent layer that blends into the pavement.
The frightening part? Drivers may not realize the road is frozen until they attempt to brake or navigate a curve.
Unlike snow covered highways, black ice often resembles ordinary wet pavement, making it especially difficult to recognize during early morning travel.
Colorado's dramatic elevation changes and fluctuating temperatures can create challenging winter driving conditions. Sunshine may melt snow during the afternoon, only for lingering moisture to refreeze after sunset.
Bridges, overpasses, shaded mountain curves and exposed roadways deserve particular attention because ice can develop even when nearby pavement appears clear.
Motorists traveling through Denver, Boulder, Colorado Springs, Fort Collins, Vail, Silverthorne and mountain communities should remain alert whenever freezing temperatures coincide with roadway moisture.
The danger can become especially serious along I 70, I 25, US 285 and US 40, where unexpected ice can leave drivers with little time to react.
Mountain passes, steep grades and winding roads create additional challenges when vehicles lose traction.
A sudden slide can result in serious collisions, injuries or fatalities, particularly on roads with sharp curves and limited shoulders.
The National Weather Service recommends checking forecasts, reducing speed, increasing following distances and avoiding abrupt braking or steering when icy conditions are possible.
Colorado motorists can monitor highway conditions, closures and travel advisories through the Colorado Department of Transportation's COtrip traveler information system.
This winter safety guidance does not confirm a statewide black ice event for Saturday, Nov. 7. Actual risks depend on local temperatures, elevation and roadway moisture.
For Colorado families planning weekend trips, the warning is simple: the most dangerous stretch of mountain highway may be the one that looks completely clear
