Every motor vehicle when operated upon a street shall be equipped with a horn in good working order and capable of emitting sound audible under normal conditions from a distance of not less than two hundred feet (200'), but no horn or other warning device shall emit an unreasonably loud or harsh sound or a whistle. The driver of a motor vehicle shall, when reasonably necessary to ensure safe operation, give audible warning with such driver's horn but shall not otherwise use such horn when upon a street. (Ord. 44-08, 6-16-2008)
