When passing a stopped emergency vehicle with flashing lights, you must
- increase your speed and change lanes.
- stop and move toward the right edge of the roadway.
- continue at the same speed and move into a non-adjacent lane.
According to Massachusetts' Move Over Law, when passing a stopped emergency vehicle with flashing lights, you must slow down to a reasonable and safe speed and move into a non-adjacent lane if possible, leaving at least one lane between you and the emergency vehicle. (Note: The laws on this are a bit different in some other states. In some states, you do not have to slow down if you can move into a non-adjacent lane. When traveling out of state, always check the local traffic laws.)
