Final answer:
When driving and encountering a pedestrian crossing the street at a green light, you should slow down and prepare to stop to ensure their safety. It's crucial to yield to pedestrians and obey traffic signals and speed limits to ensure the wellbeing of all road users, particularly in areas near campuses and other high pedestrian traffic zones.
Step-by-step explanation:
If you are driving on a city street and have the green light, but you see a pedestrian beginning to cross the street ahead of you, the correct course of action is to slow down and stop if necessary to ensure the pedestrian's safety. Despite having the green light, drivers must always yield to pedestrians to avoid accidents and ensure the safety of all road users. This is especially important in areas where traffic signals are positioned to regulate the flow of vehicles and pedestrians, such as near school campuses.
Additionally, it's essential to follow speed limits to allow enough reaction time in case pedestrians unexpectedly cross the road. Always remember that pedestrian safety is paramount and that drivers should exercise caution and be prepared to stop when necessary to prevent any potential harm.
