Under Nova Scotia's Slow Down, Move Over law, what must you do for a stopped emergency vehicle or covered tow truck with lights flashing?

1. Maintain speed unless a worker is standing in your lane
2. Slow to 60 km/h or the posted limit if lower, and move to a farther lane if safe on a multi-lane road
3. Stop for 10 minutes behind the vehicle
4. Move over only for police vehicles, not tow trucks
