I will tell you what I was told by a police officer.
Basically if you use it in a parking lot, like while you're parked, you shouldn't get a ticket. But if you use it on the street you're impersonating an emergency vehicle and will get ticketed if caught. They're illegal in california and probably most states, i think, but dont quote me.
Alot of us have them, I have one, they're fun. Just be smart when using them and don't use it around cops. Thats a given.
So far no ticket on my end, but I dont use it that much anymore. The novelty has worn off a bit.
PS: Stay away from insults, I had a buddy who had one and insulted some lady calling her a female dog.. and the lady followed them for awhile on her cell phone.. Possibly trying to get his liscense plate and talking to police.
