Final answer:
Pennant-shaped signs indicate a No Passing Zone, which is crucial for safety in areas with high pedestrian traffic, such as near schools or campuses.
Step-by-step explanation:
Pennant-shaped signs on the road indicate a No Passing Zone. These signs are important for pedestrian safety as well as vehicle safety. For example, when students and others cross intersections near campus, the presence of pennant-shaped signs can help prevent accidents by discouraging vehicles from passing in areas with high pedestrian traffic. Moreover, addressing the issue of vehicles speeding through intersections, a traffic signal in conjunction with a pennant-shaped sign would further ensure that vehicles slow down and adhere to road safety regulations, making it safer for pedestrians to cross. These signs are typically placed on the left side of the road to mark areas where passing other vehicles is not allowed. The shape of the sign, with a pointed end, makes it easily recognizable and distinguishable from other types of signs.
