Which of the following is a preventive measure against tunnel vision?

• A. Accelerating quickly
• B. Breathing, scanning, verbal narration, moving eyes and head
• C. Focusing solely on the road ahead
• D. Reducing speed to a minimum

Answer: (B)

The measure of breathing, scanning, verbal narration, and moving the eyes and head is effective against tunnel vision because it actively engages the driver's senses and cognitive functions. Tunnel vision often occurs when a driver becomes overly focused on a narrow aspect of their environment, which can lead to missing important information from the broader surroundings.

By incorporating breathing techniques, a driver can reduce anxiety and maintain calmness, which helps in making clearer observations. Scanning involves regularly looking around to ensure awareness of the entire environment, rather than fixating on a single point. Verbal narration encourages the driver to articulate their observations and intentions, reinforcing their focus on multiple elements within their field of vision. The movement of the eyes and head allows for a broader visual range, minimizing the risk of missing critical hazards.

Other options, while they may influence driving behavior to some extent, do not address tunnel vision as effectively as the selected answer. For instance, accelerating quickly or focusing solely on the road ahead could heighten the risk of tunnel vision by further narrowing the driver's attention. Reducing speed to a minimum may help in some scenarios but is not a comprehensive strategy for combating tunnel vision.
