Explanation:
The question pertains to road traffic signs indicating the beginning of a no passing zone. The correct answer to which sign marks the beginning of a no passing zone is option 4) The beginning of a no passing zone. This type of sign is crucial for road safety as it informs drivers that they are entering a stretch of road where passing other vehicles is unsafe and, therefore, prohibited. This could be due to a variety of reasons such as reduced visibility, narrow roads, or sharp bends where the oncoming traffic is not visible.
No passing zones are usually marked by road signs and sometimes supplemented by pavement markings. The signs for no passing zones are essential for preventing accidents and ensuring the smooth flow of traffic by informing drivers in advance when it is not safe to overtake.
To recognize the beginning of a no passing zone, drivers should look for a sign featuring a horizontal rectangle with a rightward pointing triangle on the left side. This sign is often yellow with black markings in the United States. Conversely, the end of a no passing zone is indicated by a similar sign but with the triangle pointing leftward, informing that the no passing restriction has ended, and it might be safe to pass again.
