There are different limits in place for different vehicle classes.
The usual 'car' on the road falls into a lower noise limit than trucks or motorcycles. Can have a noisy as Harley in a suburb, but not a noisy car.
You'll find most of it relates back to 1970's rules and regulations and hasn't been updated properly since.
A thing to note: (If I remember my sound stuff) 100db is twice as loud as 90db... It's on a logarithmic scale.
