What does the 80% rule refer to in emergency vehicle operations?

The 80% rule in emergency vehicle operations generally refers to the maximum speed an officer should drive during a pursuit. This concept emphasizes that drivers should operate at 80% of their vehicle's maximum capabilities to maintain control under high-stress conditions. This margin allows for a better response to sudden changes in traffic, road conditions, or the behavior of the pursued vehicle, reducing the risk of losing control and increasing safety for both the pursuing officer and the public.

In high-pressure situations such as vehicle pursuits, maintaining control and decision-making ability is crucial. Operating at this reduced threshold helps ensure that even when faced with unexpected challenges, the officer can react appropriately and safely, thereby minimizing the potential for accidents or injuries.
