Anyone who drives in an area with those heavy quarry dump trucks passing through has heard what engine braking sounds like. It's very loud. We have several quarries in Sussex County. Those trucks starting rumbling though Franklin, Hamburg and other towns at around 4 in the morning. Engine braking all the time. I'm on the road on my way to the radio station at that time too. My only problem with not allowing engine braking is that I wonder if it's a safety risk. Slowing down or stopping those heavy fully loaded trucks is a challenge. Engine braking is used to slow down the truck. Instead of just using the truck's brakes. There have been times when I've been cut off on Route 23 because drivers couldn't stop fast enough. Engine braking or Jake braking uses compressed gas trapped in the trucks diesel engine to slow the truck down. Yes when the gas is released it's very noisy. I just hope there is never a situation where not being able to engine brake causes an accident. The Franklin Borough Council vote was pretty decisive. Four out of five council members supported the ordinance. Now any truck driver who engine brakes in the borough faces a $100 fine.
