When approaching a police car, tow truck, or utility vehicle that is parked along the road while displaying its flashing lights, what should you do?

When approaching a stationary police car, tow truck, maintenance vehicle, or any other vehicle that is parked along the road and is displaying flashing lights, you are required to change lanes to give the stopped vehicle space, if possible. If you are unable to change lanes, slow to a safe speed as you pass.
