What are Ohio's muffler noise limits?

Ohio sets specific noise limits for vehicle mufflers to control excessive sound. These limits vary depending on the type of vehicle and testing method used.

The law requires mufflers to prevent loud or unusual noises that disturb the peace. Noise limits are measured in decibels (dB) and enforced during inspections or by law enforcement.

• Passenger vehicle noise limit: Passenger cars must not exceed 80 decibels when tested under Ohio’s official sound measurement procedures.

• Motorcycle noise limit: Motorcycles are limited to 82 decibels, ensuring they do not produce excessive noise beyond this threshold.

• Commercial vehicle standards: Commercial trucks and buses must comply with noise limits based on federal and state regulations, often stricter than passenger vehicles.

• Testing methods used: Ohio uses standardized sound meters and testing distances to measure muffler noise accurately during inspections or traffic stops.

These noise limits help reduce noise pollution and maintain community peace. Vehicles exceeding these limits may be subject to citations or required repairs.
