LAS VEGAS - A viewer says he's confused by blue lights on construction vehicles. He says he expects to see them on police and fire vehicles, but not construction vehicles.
The laws date back to 2003. With the exception of motorcycles, private vehicles are not allowed to use blue lights. State law specifies, however, Nevada Department of Transportation vehicles can use blue tail lamps for construction, maintenance or repair of highways. They can also be used for traffic control or to indicate workers are present.
Those blue tail lights cannot flash, which distinguishes them from emergency, police and fire vehicles.
NDOT says the blue lights are primarily used on slow-moving street sweepers, snow plows or trucks that haul cargo. NDOT uses them, because drivers are accustomed to yellow construction lights. The blue lights more effectively grab the attention of drivers and potentially improve safety.
