A double-deck bus is turning right from a narrow road while pedestrians wait on the corner island. What is the most complete hazard assessment?

1. Check oncoming traffic, pedestrians, offside and nearside mirrors, swept path, and rear tail swing before committing
2. Watch only the front offside corner because it reaches the hazard first
3. Begin turning and let pedestrians step back if needed
4. Ignore the rear of the bus because the front has cleared
