    a. Make a lane change into a lane not adjacent to the authorized emergency vehicle, if possible in the existing safety and traffic conditions.

    b. If a lane change under paragraph "a" would be impossible, prohibited by law, or unsafe; reduce the speed of the motor vehicle to a reasonable and proper speed for the existing road and traffic conditions, which speed shall be less than the posted speed limit, and be prepared to stop.

2. The law also applies to operators of a motor vehicle approaching a stationary towing or recovery vehicle, or a stationary highway maintenance vehicle, that is displaying flashing yellow, amber or red lights.
