The MVAR states that passenger cars (light duty vehicles) can only do a max of 83 dB. It basically just says that, and there is no further clarification on how exactly that 83 dB figure is to be interpreted, or under what circumstances it is to apply. That was one of the sticking points that I argued on in my VI complaint and subsequent OPCC rebuttal.
IMO, the reasonable interpretation based on the current MVAR is that when the vehicle is in operation (on the street), the maximum allowable sound pressure level it can produce is 83 dB. This is very much like how speed limits are enforced -- obviously all current vehicles have the
capabiltity to exceed the speed limit. But as long as they do not exceed the speed limit when it is being driven, there is no reason why it should be given a VI.
Now, the above is only my interpretation of the MVAR. I do not agree with that law itself because I think 83 dB for a passenger car is too low. For example, when going up on a hill, I think a lot of the smaller displacement vehicles can easily exceed that limit if the driver is driving properly -- ie. not lugging the engine at 2.5k rpm at 30km/h, and actually giving the it some gas and revs.
If a stock vehicle already exceeds that 83 dB limit when it is being driven normally, then I think the owner is SOL. But again, it goes back to the 83 dB limit being to artificially low.
