- Act normally. When a railway crossing is protected by a barrier, the driver is allowed to be less alert.
- Correct answer: He must always slow down.
Why this is the answer
The correct answer in the official bank: He must always slow down.
A railway crossing is a dangerous place, so a driver approaching it must slow down, even when it has a barrier and a traffic light. A train cannot stop quickly, so approach carefully, look and listen. The barrier and the traffic light do not allow you to be less alert, and care is required even when no train is seen or heard.
