Final answer:
When faced with blocked lanes, the safest action is to stop and wait until the lanes clear before making your turn. Traffic signals play a crucial role in ensuring pedestrian safety and reducing accidents at intersections.
Step-by-step explanation:
If blocked by both lanes and you need to make a quick turn to avoid a collision, the best course of action is to stop and wait until both lanes are clear. This is because proceeding to make the turn, even if there is no oncoming traffic, can be unpredictably risky if the situation changes suddenly. Additionally, honking your horn may alert other drivers, but it does not guarantee that they will give you the space to turn safely. Reversing to find an alternate route could also be dangerous, especially if there is traffic behind you. It's imperative that you prioritize safety and do not make sudden movements that could endanger yourself or others.
Pedestrian safety is a significant concern, particularly in busy intersections. To address such safety issues, a traffic signal can be beneficial. It would regulate vehicle speed, establish appropriate times for pedestrians to cross, and potentially reduce the number of accidents.
Lastly, the installation of a traffic signal can be crucial for safety at intersections. High accident rates, which may include serious injuries or even loss of life, underscore the need for such measures. A traffic signal can provide a controlled environment that significantly decreases the likelihood of accidents.
