Question

Why must bridges and overpasses never be flagged?

1) To prevent accidents
2) To ensure smooth traffic flow
3) To avoid damage to the structure
4) To maintain safety standards

Answer 1

Bridges and overpasses should not be flagged to maintain safety standards and prevent the risk of accidents and disruption of traffic. The need for a traffic signal arises when there's a high rate of accidents, threatening the safety of both drivers and pedestrians.

Step-by-step explanation:

The main reason bridges and overpasses should not be flagged is to ensure safety standards. The presence of a flag could potentially distract drivers or be interpreted as a signal, which might lead to accidents or disruption of traffic flow. When accidents occur, they can result in damage to the structure, injuries, or even loss of life.

For example, an intersection without proper traffic signals can lead to a significant increase in accidents, as vehicles may speed through without regard for the speed limit, and pedestrians are forced to dodge traffic. This situation can escalate to the point where a traffic signal is warranted to improve safety for all road users.

Therefore, while the question mentions bridges and overpasses, it's likely more concerned with the broader issue of traffic control in areas where there are frequent accidents or safety concerns. In this case, installation of a traffic signal may become necessary to reduce the number of accidents and safeguard pedestrians.
