Vehicle Equipment laws for all 50 states

[ichibankilla]

The neighbor kid was asking about ND law in regards to under body lighting and I found this link.

I thought it might make a good sticky for people who would like to know more information about local equipment laws. I know there's a few people on the forum from other states and there's been some new members recently as well, so it would be good information to have on hand.

He was also wondering why green was illegal, red is pretty much self explanatory but why green, anybody know?

And no, I personally am not putting under glow on my car.

* Red almost always denotes an emergency vehicle if the lights are facing forward. In the state of Iowa, red lights can also be used on a funeral hearse, but only during funerals. In Washington State, red lights are also used on tow trucks, but only if the vehicle is not in motion.
* Amber or Yellow lights are often used by vehicles such as construction vehicles, tow trucks, snow plows, funeral escorts, security patrol vehicles or other vehicles which may be stopped or moving slower than the flow of traffic. Amber is usually the most permissively regulated color.
* White is often used as an optional color on lightbars, though it may be restricted to emergency vehicles in some states. It is rarely used as the only color on a lightbar, though Arkansas, Rhode Island, Florida, Illinois, Michigan, Wisconsin, Maryland, West Virginia, South Dakota and Kentucky require flashing white beacons on school buses. Certain railroad-related machines, like fueling tankers or switching engines, may also use a flashing white light.
* Green on a fire chief's car or a mobile command post denotes the command vehicle on scene; this usage derives from the use of green flags in the Incident Command System. Green can also denote a firefighter or EMT's vehicle in some states. In some states, green is used by private security guards.
* Blue is reserved for law enforcement, firefighters and EMTs. In New Mexico, tow trucks have blue lights. In Texas light Construction vehicles use Blue along with Amber. Alaska, Arizona, Colorado, Minnesota, and Nebraska also use blue lights on snowplows.[31][32][33]
* Purple is permitted in some states to denote a funeral vehicle.[34][35][36][37]

Green in some states is also on top of ambulances. If it's dark out they turn on the green light (not sure if it strobes or spins or what) and aim their headlights in the direction of the area they want the helicoptor to land. Not sure if it is used locally, but i know it's used in some areas.

You guys are missing the obvious one in traffic signals. I was told that has something to do with it when I asked that exact question of the States Highway Patrol office.
