What is the key aspect of defensive driving?

The key aspect of defensive driving is being aware of developing traffic situations. This means maintaining a heightened sense of awareness of your surroundings while driving, including the behavior of other drivers, pedestrians, road conditions, and any potential hazards. By being attentive and anticipating possible changes in the traffic environment, a defensive driver is better equipped to react appropriately to unexpected developments, thus reducing the risk of accidents.

Keeping your eyes only on the road ahead limits your field of vision and may cause you to miss critical information from the sides or behind you. Ignoring other vehicles can lead to dangerous situations since other drivers may act unpredictably. Staying hydrated is important for overall health but does not directly relate to the practice of defensive driving, as it doesn't enhance awareness or improve driving safety.
