Q&A - Are Police Qualified to Decide on Noisy Exhausts?
Is a Police officer also an inspector under the motor vehicle regulations? For noisy exhausts it is the opinion of the inspector that seems to critical in determining whether the vehicle exhaust is too noisy.
So it would be great if a police officer could issue a ticket or a notice to correct just based on their opinion, which should be just more useful than trying to do decibel testing.

Question: I have been trying to find specifics on what is the difference between off road lights and driving lights. All I can see is the indicator of SAE-Y on the lens, is this the only difference?
