This the law for Emergency Vehicles:
257.653 Immediate approach of authorized emergency vehicle; duty of driver of another vehicle; duty of streetcar operator; violation as civil infraction.
Sec. 653. (1) Upon the immediate approach of an authorized emergency vehicle equipped with not less than 1 lighted flashing, rotating, or oscillating lamp exhibiting a red or blue light visible under normal atmospheric condition from a distance of 500 feet to the front of the vehicle and when the driver is giving audible signal by siren, exhaust whistle, or bell:
(a) The driver of another vehicle shall yield the right of way and shall immediately drive to a position parallel to and as close as possible to the right-hand edge or curb of the roadway, clear of an intersection, and
shall stop and remain in that position until the authorized emergency vehicle has passed, except when otherwise directed by a police officer.
(b) The operator of a streetcar shall immediately stop the car, clear of an intersection, and shall keep it in that position until the authorized emergency vehicle has passed, except when otherwise directed by a police officer.
(2) This section does not relieve the driver of an authorized emergency vehicle from the duty to drive with due regard for the safety of persons using the highway.
(3) A person who violates this section is responsible for a civil infraction.
So, you need to pull to the right hand curb, or as close as possible, and remain until the EV has passed.
