Is that legal?
We have noise limits depending on zone and time. You can't rock a party bus in a residential neighbourhood.
If it was here I would suggest recording the van, with the logo and noise, and send it to by-law enforcement.
Not sure how that would/wouldn't work in your area.
I'm actually not sure. If the source of the noise is coming from a house, you can get warnings from the police and end up being evicted.
The only laws I can think of that may apply are disturbance of the peace stuff, but that's intended for more malicious acts. I actually would not call any kind of law enforcement for this though, because there have been severe police cuts across the country and my area specifically has been badly affected. Even community support officers are few and far between here.
I don't understand what's happening.
Is the music coming from a car parked outside?
Why?
