• Abstract:
  Orange plastic drums are common on Florida roadways, warning motorists and guiding them safely through work zones. The orange color is mandated by the Manual on Uniform Traffic Control Devices, which also requires that drums bear retroreflective white and orange sheeting when used at night. But Florida also requires warning lights on channelizing devices and temporary barriers. Past studies have shown that warning lights aid driver detection of safety devices, but more recent work, following introduction of high-intensity retroreflective materials, which are brighter at greater distances, has brought into question continued use of warning lights.
