Is it allowed to pass a railroad crossing in this situation?
Prohibited.✓پاسخ درست
Allowed if no train is approaching.
Allowed, if the crossing guard on duty forbids oncoming traffic.
توضیح
The crossing attendant is displaying a red flag toward the road, which is a stop command for approaching traffic. Raised barriers and unlit crossing lamps do not cancel a direct prohibitory signal from the attendant.
