What is the Point of possible perception?

• A. The Point Of Possible Perception
• B. The Point Where A Hazard Is Actually Seen By The Driver
• C. The Moment The Driver Has Decided To Brake
• D. The Distance At Which A Driver First Reacts

Answer: (B)

Hazard perception hinges on recognizing a hazard as soon as it becomes visible to the driver. The Point of possible perception is the moment when the hazard is actually seen by the driver. That moment is the start of your response window—once you notice it, you can decide to brake or steer to avoid danger. It’s not the moment you decide to brake (that comes after seeing the hazard), nor the distance you travel during your reaction time. Nor is it just a theoretical possibility of noticing a hazard; it’s the actual moment you first see it. For example, if a pedestrian steps onto the road, the instant you spot them is the point of possible perception.
