It is necessary to stop before the second sign.✓Correct answer
It is necessary to stop at a distance of at least 5 meters from the first railway line.
Explanation
The first sign is STOP, and the second is the railway crossbuck marking the crossing. Because no stop line is shown, the driver must stop immediately before the crossing boundary indicated by the crossbuck. Stopping beside the earlier STOP sign or using a separate five-metre setback would not place the stop at the marked boundary.
