What kind of driving is least likely to involve you in a traffic crash?

Defensive driving is a proactive approach that emphasizes anticipating and reacting to potential hazards on the road. The reason the correct choice focuses on preparing for unexpected shifts in traffic is that it highlights the importance of being adaptable and aware of changing conditions. This mindset allows a driver to recognize potential dangers and classically avoid hazardous situations, thereby minimizing the risk of being involved in a traffic crash.

When a driver is prepared for unexpected events, such as sudden stops by other vehicles, pedestrians entering the roadway, or changes in weather conditions, they are more likely to react appropriately and maintain control of their vehicle. This reduces the likelihood of accidents, as defensive drivers are vigilant and equipped to handle various situations that could lead to a crash.

The other options relate to driving styles that either lack consideration for safety or emphasize aggression, which increases the risks on the road. In contrast, the focus on preparedness in this context is central to ensuring safety while driving.
