Newspaper and mail delivery vehicles have flashing yellow lights on top, which show other drivers that they will likely need to pass to get around the slow moving vehicles which may make unexpected stops.

This type of light might be useful for Engine Off Coasting, to encourage people to pass and to warn of nonstandard driving behavior. For example, I like to coast down to 30mph before restarting and running through 4rth and 5th gear. I would prefer if other drivers passed when they have the opportunity. A flashing yellow light might encourage the timid or overly polite.

When I get some time, I will look through the motor vehicle code and see if and when using a flashing yellow light is permitted.

Anyone else use one of these? Anyone think this is a good/bad idea?
