I actually found a decibel limit in some other bill/act that had a specific number for passanger vehicals... i'll try to look it up
edit: found it
the Motor Vehicle Safty Act... it says 80db, the 95 number is in California but for some reason everyone likes to apply it to everywhere else in northamerica
