What does defensive driving primarily involve?

Defensive driving primarily involves continuous visual scanning of the driving environment. This technique is vital because it allows a driver to be aware of potential hazards or changes in the surroundings, including other vehicles, pedestrians, traffic signals, and road conditions. By scanning the environment consistently, drivers can anticipate and respond to situations that may pose a risk, such as sudden stops, aggressive driving from others, or obstacles in the roadway. This proactive approach not only helps in preventing accidents but also enhances overall road safety.

The other options do not align with the fundamental principles of defensive driving. For instance, while using a GPS can aid navigation, it does not contribute to situational awareness. Speeding, even if perceived as necessary, contradicts the defensive driving philosophy, which emphasizes safe driving practices within the speed limits. Listening to music can be distracting and may detract from the driver's ability to remain focused on the road and their surroundings, which is contrary to the essence of defensive driving.
