The police do not have a quota for tickets, they do not get paid any more if they write more, all writing more tickets does is create mountains of paperwork that actually keeps the officer off of the streets, ever said where's a cop when you need one? He's probably doing your paperwork. Now someone replied that they listen to their music loud only on the highway and are just waiting to have an ambulance or that come up behind them one day and not be noticed, no offense dude but if you drive with this position, then you should not be driving, you are a hazard to the other drivers. Now after I explain why you'll probably have a different opinion, so why? Because unless you can drive using "the force" our #1 reason for being able to drive is being able to see. Being able to hear a siren does not make you a better or safer driver, you should always be checking your mirrors every 15 - 30 seconds. How do you know that some semi that has lost it's brakes and has no air horn (I have seen this personally) isn't heading straight for your rear bumper? Ever wondered how a deaf person can drive? What about people who wear hearing protection while they drive ,ever driven a really loud diesel? Just a different side of the coin for your reply and I hope that you'll see the point here, I am not calling you a hazard as was implied above, just opening other peoples eyes to how they really drive.
Now the police have a job to do, they are there to enforce the laws. If they law states that there can be no loud noise and they catch you, you are guilty. The officer may not agree with the law and I know that you definitely don't but he has a job to do and he will do it. Yes there is a drastic difference for the officer between a domestic violence call and a ticket for excessive noise, but nonetheless if you break the law and he sees you break the law, you will be given a ticket, maybe not right now, maybe in 2 weeks because he was on the way to a domestic disturbance call, and maybe he'll also send the guy a ticket that failed to pull to the right and stop when he approached your vehicle from behind. (you didn't hear him - and don't dispute this, you will lose). The officer's job is no different than the job that we must do every day, how long do you think you would have a job if you did not do what your employer wants to do, no difference for the officer.
There is a time and a place to play a audio system loud, it is most certainly not in an area that will annoy people on a daily basis, be it at work or at home or in your neighbourhood where everyone can see you, follow you home and steal your stereo. This happens way more often than you think. I as a business owner of two car audio stores happen to agree that there should be some kind of laws against noise pollution, be it a loud Harley, construction site work or a big car audio system, but to enact a blanket law is exactly the wrong way to go, one size does not fit all.
