What is a hazard?
Here are a few examples of hazards that you may need to react to:
Traveling through a side street lined with parked cars, a child steps out. Approaching a green light at 70 km/h, a pedestrian steps onto the road.
Speedo reads 80 km/h while you are on a bend; that is probably a bit quick.
Approaching a green light at 60 km/h and the lights go yellow suddenly.
Approaching a green light and the oncoming vehicle turns in front of you.
Approaching a right turn (green light) and a motorcycle is approaching (but is hidden).
Following a vehicle and a cloud of dust appears under that vehicle.
Warning sign for bad road conditions while cruising at 80 km/h.
Following a tram, it gradually slows down, very hard to pick though.
Following a bicycle at 20 km/h, choosing a time to overtake it.
