Warning device on Ridge Road reminds drivers of posted speed limit
Lights from a coal truck pass a speed warning device on Ridge Road on Tuesday night, where truck drivers and other motorists were reminded of a reduced speed limit as they approached U.S. Highway 6. The long shutter speed in this shot captured readings on the sensor between 35 and 45 mph. For many motorists, speed sensors are common sights in residential areas and school zones, where lower speed limits are enforced. However, they are not uncomon on major coal routes and other heavily used roads.
