    There used to be trouble is do you know anyone with a meter to measure it ? thinks its 75 db not very loud last time i got stopped long ago, i told the copper i bought it as legal and he let me go just told me to keep it down in built up areas and enjoy it where you have the space. if your gonna act like an arse the law will treat you like one.

    Dont think theres a DB legal limit on any car as such,but if the old bill think its loud,they can use the car of a similar type ****,Think @ the end of the day its up to the individual copper,out of interest is it a blowning exhaust noise or just a loud v8 rumble type noise.

    I think my own car is around the 50 db level when in park and the engine switched off.

    Used to covered in "Construction and use" regs, vehicles registered up to 2009 the maximum is 101 dbA after that it is 99 dbA. I'd advise going to an official VOSA test station and get the car concerned tasted and then you know what figure you're talking about, That's if you want to contest it.
    This test will be carried out under specific laid down conditions.
    Think you'll find the 75 dbA is the up to date drive by limit.
    This stuff really ****es me off, when there is a set in stone limit why don't they impliment it and not use guesswork and opinions to enforce a sperious "law".

    From Aces site, re one particular force and their limits..

    In regard to the motorist issued with the FPN, the report say that his vehicle was found to be putting out 93dB.
    The maximum permissible level to pass the BIVA test is 98dB, which is down from the SVA limit of 101dB.


    That makes no sense to me. If I read it right, he could pass a BVA test, and then get done by plod on the way home??????

    As Phunkie says it is written in C&U regs. I got done once under the particular section number which stated a db level. Took it to court on the basis that no actual meter reading was taken, it was just the officers opinion that it was too loud. I won that case but if I had been done under a different regulation number then no meter reading would have been necessary.

    This is all correct.

    The BIVA and SVA tests were done at 2/3rd of the max engine power rpm. So if you make peak power at 6k then the test is at 4k.

    My kitcar went through the 101dB test, just. It was 100dB, and that is fecking loud!

    Well I have a question
    My bike is 1960 reg and is very loud, is there a limit for old vehicles.
    It passes the MOT but with an advisory of "exhaust a bit noisy"
