A driver should look seconds ahead for medium-distance potential hazards?

A driver should look several seconds ahead to identify potential hazards that may arise within medium-distance ranges, typically around 12 to 15 seconds ahead. This proactive approach allows for better decision-making and timely reactions, such as adjusting speed or changing lanes. By anticipating possible dangers, drivers can enhance safety for themselves and others on the road. Overall, maintaining awareness of the environment ahead is crucial for effective defensive driving.
