Many towns are beginning to outlaw Engine ("Jake" ) Braking except in emergencies.
As an aside: many of the towns have signs saying "No Jake Braking". These are incorrect and should be "No Engine Breaking" or "No Compression Braking". Jacobs Vehicle Systems has threatened to sue any municipality using the term "Jake Brake". Springdale, AR changed their signs a few years back after being contacted by lawyers representing Jacobs.
If they would pay me, I'd travel around shooting photos of all the "Jake Brake" signs so the lawyers could notify everyone
