"When it comes to the most dangerous winter highways in the U.S., the pattern is clear: the ones exposed to quick weather changes, complex traffic movements, and terrain features that magnify the effects of ice and snow rise to the top. Each winter, these highways stand out for how quickly conditions can turn dangerous. Forecasts can shift without warning, and familiar routes can behave unpredictably when cold air or fast-moving squalls roll in. These corridors see sudden temperature drops, rapid icing,"
"The data used to determine the most treacherous winter roads comes from Samsara's multi-year analysis, which highlights several corridors that consistently show some of the sharpest increases in winter crash rates. The top nine are listed below. Winter Crash Rate Increase: 230% Top hotspot locations: Newark Bay / Jersey City interchange zone. Winter Crash Rate Increase: 263% Top hotspot locations: North Platte; Kearney to Grand Island; Lincoln to Omaha."
Highways exposed to rapid weather changes, complex traffic movements, and certain terrain features produce some of the most dangerous winter driving conditions. Sudden temperature drops, rapid icing, limited visibility, wind-driven drifts, and early bridge freeze events can make familiar routes unpredictable and raise crash risk. A multi-year Samsara analysis identifies nine U.S. corridors with consistently sharp winter crash-rate increases, ranging from 230% to 450%. Notable hotspots include Newark Bay/Jersey City; Nebraska corridors between North Platte, Kearney, Grand Island, Lincoln, and Omaha; South Chicago/Calumet; Colorado mountain corridors including Eisenhower/Johnson Tunnels and Vail Pass; Flagstaff/I-17–I-40; West Memphis/Little Rock; and Wyoming routes near Elk Mountain and Laramie.
