Defensive driving is a set of driving techniques that are used to help reduce the risk of accidents, and to minimize the severity of any accidents that do occur. It involves anticipating potential hazards on the road, and taking appropriate action to avoid them. Some specific elements of defensive driving include:

1. Maintaining a safe following distance: This involves keeping a safe distance between your vehicle and the one in front of you, so you have time to react if the other driver does something unexpected.
2. Using proper lane position: This involves positioning your vehicle in the correct lane for the conditions and your intended direction of travel.
3. Avoiding distractions: This includes things like texting or eating while driving, as well as other activities that can take your attention away from the road.
4. Being alert and aware: This means keeping an eye out for other vehicles, pedestrians, and other hazards, and being prepared to take evasive action if necessary.
5. Anticipating potential hazards: This involves looking ahead and trying to anticipate what other drivers, pedestrians, or other hazards might do, and taking action to avoid potential problems.

Overall, defensive driving involves being aware of your surroundings and taking proactive steps to reduce the risk of accidents, rather than simply reacting to events as they unfold.
