Michigan Compiled Laws, Chapter 257. Motor Vehicles § 257.650

Sec. 650. (1) The driver of a vehicle within an intersection intending to turn to the left shall yield the right of way to a vehicle approaching from the opposite direction which is within the intersection or so close to the intersection as to constitute an immediate hazard; but the driver, having so yielded and having given a signal when and as required by this chapter, may make the left turn and the drivers of all other vehicles approaching the intersection from the opposite direction shall yield the right of way to the vehicle making the left turn. At an intersection at which a traffic signal is located, a driver intending to make a left turn shall permit vehicles bound straight through in the opposite direction which are waiting a go signal to pass through the intersection before making the turn.

(2) A person who violates this section is responsible for a civil infraction.
