Gusty Winds Area
Strong, sudden crosswinds may affect vehicle handling along this stretch of road.
Posted on bridges, mountain passes, open-plains highways, and other corridors where crosswinds are common, this warning alerts drivers (especially those in high-profile vehicles, with trailers, or on motorcycles) to expect sudden lateral pushes. Slow down, hold the wheel firmly with both hands, and allow extra room for vehicles that may be blown off course.
