Final answer:
To ensure road safety when changing lanes or passing, it's essential to signal your intentions. Traffic signals help manage vehicle speeds and enable safe pedestrian crossings, and understanding traffic patterns is crucial for crossing roads safely.
Step-by-step explanation:
When passing, beyond checking for safety in all directions, it is mandatory to signal the direction you are planning to go before executing the maneuver. This communication allows other road users to anticipate your actions, increasing safety for everyone involved, including pedestrians, bicyclists, and other motorists.
Pedestrian safety is a significant concern at busy intersections or when crossing roadways. For instance, traffic signals play a crucial role in managing vehicle speeds and providing safe crossing opportunities for pedestrians. Understanding the context of a traffic situation is vital for pedestrian safety. It is generally advisable that a pedestrian estimates a safe distance from oncoming cars before attempting to cross a road, often referred to as judging car-lengths for crossing.
