Under New York's Move Over Law (VTL 1144-a), what must a driver do when approaching a stopped emergency vehicle with flashing lights?

1. Reduce to 15 mph and continue in the adjacent lane without moving over
2. Move over one lane from the emergency vehicle or slow down if a lane change is not safe
3. Stop completely behind the vehicle until its operator waves traffic onward
4. Continue at normal speed whenever the stopped vehicle is not in your lane
