A. "Dynamic braking device" on commercial vehicles (commonly referred to as a Jacob or Jacob's brake, engine brake, or compression brake), means a device used primarily on trucks for the conversion of the engine from an internal combustion engine to an air compressor for the purpose of braking without the use of wheel brakes.
B. It is unlawful for any person to operate any vehicle with a dynamic braking device engaged, except for the aversion of imminent danger, within the Plain City limits. Firetrucks and other emergency vehicles shall be exempt from the prohibitions of this section. (Ord. 2023-08, 6-1-2023)
