Ohio Engine & Jake Brake Rules

No statewide ban on engine braking in Ohio. State law is the muffler statute (ORC 4513.22): a muffler in good working order and constant operation, no cutout or bypass. Break it and it is a minor misdemeanor, up to $150. The actual jake-brake bans are city ordinances. Municipalities on truck routes post 'no engine braking' signs at their limits and write local citations. Ease off through the posted zone. Keep the engine brake on for the grades that have none.
