To drive **defensively**, it is not enough to just observe. It is essential to keep in mind that other drivers may make mistakes or commit infractions. Defensive driving involves:

- **Vision**: Not only looking ahead, but also to the sides and into the distance to get a complete view of the surroundings. This helps identify potential hazards before they become problems.

- **Anticipation**: Foreseeing the movements and reactions of other drivers. This means being prepared for any unexpected actions they may take, such as suddenly braking or changing lanes without signaling.

- **Space**: Always maintaining a safe distance from the vehicles around you. This gives you time and space to react if another driver makes a mistake.

Additionally, defensive driving requires **adapting to the circumstances** of the journey and being prepared to react to unforeseen events. This means that, even if you observe and follow the rules, you must always be alert and ready to act if another driver makes a mistake. Therefore, it is crucial to remember that observation is only one part of safe driving; anticipating the mistakes of others is equally important.
