What is the most important defense against impairment that can lead to a collision?

Making sure all passengers are wearing seatbelts
Avoiding bad areas
Having adequate insurance
Driving defensively

The correct answer is: Driving defensively

Driving defensively is the most important defense against impairment that can lead to a collision because it involves actively anticipating and avoiding potential hazards on the road, such as impaired or distracted drivers. Option A, wearing seatbelts, is important but it does not prevent impairment. Option B, avoiding bad areas, is not a specific defensive driving strategy and may not always be possible or effective. Option C, having adequate insurance, only addresses the aftermath of a collision and does not prevent it from happening. Therefore, driving defensively is the most important defense against impairment and potential collisions.
