Interesting they are concentrating on the noise aspect. Prehaps they will turn their attention to the use of the own sirens and horns, which are becoming a major noise nuisance in my area. Before any one starts, I'm talking about the EARLY hours of the morning when I can assure you that the roads in my local are deserted. The nearby ambulance station still throws open the yard gates , switches on the sirens and races off. Why, they could at least wait until they came across some traffic obstructing their thru passage but I repeat. the roads really are deserted and I see no reason for putting the sirens on as a matter of routine.

Its like anything these days,its a back covering excercise. If they pulled out of the gate and didn't have the blues and two's on and someone came out of know where and an accident occured you can garuantee that the poor old ambulance driver would be dragged over the coals for it, and then people would be saying, "why the hell didn't they have the siren on". Damned if you do and damned if you dont.

I think the law on exhausts is a very grey area. I was having my TVR MOT'd and asked the tester if there was a noise 'limit' as my car is quite loud. He said there wasn't but if the noise wasn't part of the cars design then you could get in trouble. i.e. sports car = fine, but 1.2 Saxo with a cherry bomb = not. Coupled to that, when the fuzz target the 'cruise' culture they often find that it is rich pickings as far as insurance, MOT , tax evaders go as a lot of these kids would rather spend on neons etc than get a licence and insure the thing. I bet loads of these kids don't inform the insurers about the mods either.

However the bike MOT is different. The law has come down on testing stations who pass race exhausts and so getting a bike MOT'd with a loud exhaust is tricky. My Ducati is done at a place who interpret the law in my favour. Ironically, a loud bike exhaust is a great safety feature.

How is it then that the police can pull over rally cars driving between stages and do the driver for loud exhausts?

I thought there was a limit of 75dB but I have no idea the measurement criteria!

At the TVR MOT he didn't measure the noise of the exhaust. No need and no equipment. I think it is down to individual interpretation most of the time.
