Salem, OR – A highway that looks perfectly safe could conceal a dangerous surprise for Oregon 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 lose traction.
According to the National Weather Service, black ice can form when rain, melting snow or lingering roadway moisture freezes, creating a thin, nearly transparent coating that blends into the pavement.
The frightening part? Drivers may not recognize the danger 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 identify during early morning travel.
Oregon's combination of frequent rainfall, mountain snowfall and changing temperatures can create challenging winter driving conditions.
In western Oregon, moisture left behind by rain can freeze when temperatures drop sufficiently. Across central and eastern Oregon, colder overnight conditions can also create hazardous patches of ice.
Bridges, overpasses, shaded curves and elevated roadways deserve particular attention because they can freeze before nearby pavement.
Motorists traveling through Portland, Salem, Eugene, Bend, Medford, Pendleton and communities throughout the state should remain alert whenever freezing temperatures coincide with roadway moisture.
The danger can become especially serious along I 5, I 84, US 97 and US 26, where unexpected icy patches can leave drivers with little time to react.
Mountain crossings such as Santiam Pass, Willamette Pass and Government Camp present additional challenges, including steep grades, sharp curves and rapidly changing weather.
A sudden loss of traction can result in serious collisions, injuries or fatalities, particularly on winding roads or busy interstate corridors.
The National Weather Service recommends checking forecasts, reducing speed, increasing following distances and avoiding abrupt braking or sharp steering when icy conditions are possible.
Drivers can monitor highway conditions, mountain pass restrictions and traffic cameras through the Oregon Department of Transportation's TripCheck 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 Oregon families planning weekend travel, the warning is simple: the most dangerous stretch of highway may be the one that looks completely clear.
