Ohio Revised Code Title XLV. Motor Vehicles Aeronautics Watercraft § 4513.171

(A) Notwithstanding any other provision of law, a motor vehicle operated by a coroner, deputy coroner, or coroner's investigator may be equipped with a flashing, oscillating, or rotating red or blue light and a siren, whistle, or bell capable of emitting sound audible under normal conditions from a distance of not less than five hundred feet. Such a vehicle may display the flashing, oscillating, or rotating red or blue light and may give the audible signal of the siren, exhaust whistle, or bell only when responding to a fatality or a fatal motor vehicle accident on a street or highway and only at those locations where the stoppage of traffic impedes the ability of the coroner, deputy coroner, or coroner's investigator to arrive at the site of the fatality.

This section does not relieve a coroner, deputy coroner, or coroner's investigator operating a motor vehicle from the duty to drive with due regard for the safety of all persons and property upon the highway.

(B) Whoever violates this section is guilty of a minor misdemeanor.
