Traffic advisor (directional) lighting on trucks
Got into a discussion with one of the safety officers the other day over something I've wondered about, but our dept. doesn't have an SOP on it. Our trucks are equipped with the yellow traffic advisor (directional) lights, which you can use to get traffic to go to one side of the truck or the other. I've noticed some guys drive around with the lights on what I call a "scramble" pattern (random) all the time. I'm thinking people may become too accustomed to the lights on the truck and not realize the truck is stopped and they are using the lights. One person we asked thought there was an NFPA standard on them. What are your experiences and SOP's?
