Heavy snow turned a steep roadway into a danger zone in the Lake Tahoe area on Tuesday, as cars and tractor-trailers slid uncontrollably into each other. Video shows multiple vehicles losing traction on an icy hill, triggering a chain-reaction crash as drivers struggled to stop or steer on snow-covered pavement. Several vehicles slid backward and sideways, leaving little room to escape once momentum took over. #LakeTahoe #Snowstorm #WinterWeather #IcyRoads #TruckCrash #CarCrash #BreakingNews #CaliforniaWeather #RoadConditions #ExtremeWeather
