I live in Northern Pa, our district runs to the New York State Border, I have heard in NY it is a state law to pull over for a blue light, is this true? Also wondered how many other states are like this, and how something like this would take affect?
NM has no such law. There is no coordinated emergency law in the state. Volunteers can run emergency lights IF their local jurisdiction allows it and issues an emergency vehicle permit. Some city/counties do, some don't. Our county does for chief officers but the requirements are insane so not many do. Ours, and other dept's have gotten around this by providing chief officers with department vehicles. Statewide they can't seem to get coordinated some cops run red, some red/blue, some red/amber. must fire run red or red/amber. we run red/blue. Even tow trucks are not coordinated , some run blue some amber, some combination. It is a little ridiculous that we don't have a state coordinated policy . If we did then I would support the blue " courtesy light" . Personally I find amber to be unsafe when operating in or very near a roadway , traffic just ignore it because they think it is work/construction. Red and blue work because they think they might get a ticket.
In Calif, vollies are prohibited from having any kind of warning lights/devises and flashing blue lights are for law enforcement only. There is no provision for using a solid blue light. However, legally a law enforcement officer is supposed to display at least one forward facing solid burning red light to be considered operating "code 3". Also, it is incorrect that responders can have a rear amber flasher. 25253-25258 CVC designates who is permitted to have a rear flasher.
