What must drivers do at a railway crossing?

At a railway crossing, it is essential for drivers to stop at the marked line and look for trains. This practice ensures that drivers take the necessary precautions before proceeding, as trains can approach unexpectedly and travel at high speeds. Stopping allows drivers to assess the situation carefully and ensure that the crossing is clear before continuing.

By looking for trains, drivers can also be aware of any warning signals or lights that may be activated, indicating that a train is approaching. This proactive safety measure helps to prevent accidents and increases pedestrian, passenger, and driver safety at these potentially dangerous intersections.

Other options may suggest inadequate safety measures, like simply slowing down or ignoring warnings, which doesn't prioritize the driver's responsibility to ensure that it is safe to proceed. Therefore, stopping and actively looking for trains provides the best approach to ensure safety at railway crossings.
