Make sure that all the pedestrians have crossed in the non- crossing section of the crosswalk✓Correct answer
When the traffic light signal is on, immediately drive on
Explanation
The English option texts diverge from the source editions: the accepted source response requires checking the concealed part of the crossing for pedestrians still finishing, not a nonexistent non-crossing section. The truck blocks the driver's view, so a newly permissive signal does not prove that the entire marked route is clear.
