Michigan § 257.603 - Applicability of chapter to government vehicles; exemption of authorized emergency vehicles; conditions; exemption of police vehicles not sounding audible signal; exemption of persons, vehicles, and equipment working on surface of highway.

The provisions of this chapter applicable to the drivers of vehicles upon the highway apply to the drivers of all vehicles owned or operated by the United States, this state, or a county, city, township, village, district, or any other political subdivision of the state, subject to the specific exceptions set forth in this chapter with reference to authorized emergency vehicles.

The driver of an authorized emergency vehicle when responding to an emergency call, but not while returning from an emergency call, or when pursuing or apprehending a person who has violated or is violating the law or is charged with or suspected of violating the law may exercise the privileges set forth in this section, subject to the conditions of this section.

The driver of an authorized emergency vehicle may do any of the following:

Park or stand, irrespective of this act.

Proceed past a red or stop signal or stop sign, but only after slowing down as may be necessary for safe operation.

Exceed the prima facie speed limits so long as he or she does not endanger life or property.

Disregard regulations governing direction of movement or turning in a specified direction.

The exemptions granted in this section to an authorized emergency vehicle apply only when the driver of the vehicle while in motion sounds an audible signal by bell, siren, air horn, or exhaust whistle as may be reasonably necessary, except as provided in subsection (5), and when the vehicle is equipped with at least 1 lighted lamp displaying a flashing, oscillating, or rotating red or blue light visible under normal atmospheric conditions from a distance of 500 feet in a 360 degree arc unless it is not advisable to equip a police vehicle operating as an authorized emergency vehicle with a flashing, oscillating or rotating light visible in a 360 degree arc. In those cases, a police vehicle shall display a flashing, oscillating, or rotating red or blue light visible under normal atmospheric conditions from a distance of 500 feet to the front of the vehicle. Only police vehicles that are publicly owned shall be equipped with a flashing, oscillating, or rotating blue light that when activated is visible under normal atmospheric conditions from a distance of 500 feet in a 360 degree arc.

A police vehicle shall retain the exemptions granted in this section to an authorized emergency vehicle without sounding an audible signal if the police vehicle is engaged in an emergency run in which silence is required.

The exemptions provided for by this section apply to persons, teams, motor vehicles, and other equipment while actually engaged in work upon the surface of a highway but do not apply to those persons and vehicles when traveling to or from work. The provisions of this chapter governing the size and width of vehicles do not apply to vehicles owned by public highway authorities when the vehicles are proceeding to or from work on public highways.
