What percentage of incoming data to a driver is supplied by vision?

Vision is the most critical sense for driving as it provides the majority of the information that a driver needs to navigate effectively and safely. Research indicates that approximately 90-95% of the incoming data a driver relies on while operating a vehicle comes from visual sources. This includes not only seeing the road and surrounding environment but also detecting other vehicles, pedestrians, traffic signals, and various hazards.

This high percentage highlights the importance of visual awareness and the need for drivers to remain vigilant and attentive, as a significant portion of situational awareness stems from what they can see. Understanding this statistic underscores why visual distractions can severely impede driving performance and why maintaining good vision is crucial for safe driving practices.
