What is the key principle of defensive driving?

The key principle of defensive driving is being prepared for unexpected actions from other drivers. This approach emphasizes the importance of vigilance and anticipation in driving situations. It encourages drivers to stay alert and aware of their surroundings, anticipating that other drivers may not always follow traffic laws or may make sudden, unpredictable movements.

This principle helps enhance safety on the road by ensuring that drivers maintain a proactive mindset. It involves scanning the environment regularly, being aware of the behaviors of other vehicles, and being ready to react appropriately in various scenarios, whether it's an unexpected lane change, sudden stop, or distraction from another driver.

This mindset reduces the likelihood of accidents because the defensive driver is not just focused on their immediate actions but also considers the potential actions of others. The other options do not align with the comprehensive strategy of defensive driving; they either focus on compliance with rules or self-centered driving, which doesn't account for the shared responsibility of all road users.
