Near Haarlem you approach a level crossing. By the track a white light is flashing; the red lights are off. What do you do?
You drive on calmly; the flashing white light reports that no train is approaching
You wait before the track; the flashing white light reports that a train is about to come
You stop before the track; the flashing white light reports danger at the crossing
Explanation
False — you read the flashing white light as an announcement of a train. Flashing white means precisely that no train is approaching; when a train comes, the red lights flash and you must stop. Book p.55-57.
