Hi There,

In your article **What are “jake brakes” and why are they prohibited in some locations?** there is a very good link-to url to find more detailed information regarding the JakeBrake and noise.

Thanks!

I work for a trucking firm here in Portland, Oregon. I don’t know about our owner-operators, but I know for a fact that the company tractors use authentic JakeBrakes, and they are not that noisy at all.
