To help avoid tunnel vision in a pursuit, which rule is recommended?

The recommended rule to help avoid tunnel vision in a pursuit is the 2-4-12 rule. This rule emphasizes the importance of maintaining a visual scanning pattern that allows drivers to keep a broader awareness of their surroundings, rather than focusing solely on the immediate target or path ahead.

By adhering to the 2-4-12 rule, operators are encouraged to check their immediate environment (2 seconds ahead), then look 4 seconds ahead for upcoming obstacles or changes in the situation, and finally scan 12 seconds ahead to anticipate future developments. This practice helps ensure that the driver is conscious of potential hazards, other vehicles, and pedestrians, thereby reducing the risk associated with tunnel vision in high-stress situations like a pursuit.

This approach is critical in emergency driving situations where situational awareness can directly impact safety and decision-making. Keeping a balance between short and long-range vision supports better control and responsiveness on the road. Thus, the 2-4-12 rule effectively counteracts the narrowing of focus that can lead to dangerous outcomes during a pursuit.
