Final answer:
The answer describes the correct behavior when an ambulance approaches while waiting to make an unprotected left turn: stop and remain stationary. Additionally, it discusses the importance of traffic signals for pedestrian safety and accident reduction near high-traffic areas like school campuses.
Step-by-step explanation:
The best position to take when waiting to make an unprotected left turn is behind the stop line or crosswalk. When an ambulance is approaching, one must stop moving and become stationary until it passes by. This action prioritizes pedestrian safety and ensures that one doesn't interfere with emergency services.
It's important to consider the broader implications of road safety, such as at busy intersections near campuses where students are at risk due to high traffic volumes. Installing a traffic signal at problematic intersections is one measure that can help slow down speeding vehicles and allow pedestrians to cross safely at appropriate times. This not only reduces the incidence of accidents but also the severity of those that may occur.
Overall, safety laws and signals are put in place to manage the flow of both vehicles and pedestrians, creating a safer environment for all parties involved.
