What proportion of pedestrians are estimated to survive an impact with a vehicle traveling at 40 mph?

When considering the survival rates of pedestrians involved in accidents with vehicles, a significant body of research indicates that as vehicle speed increases, the likelihood of survival decreases dramatically. At a speed of 40 mph, statistics typically show that around 90% of pedestrians are estimated to survive an impact. This high survival rate at 40 mph can be attributed to several factors, including the nature of the impact and the effectiveness of modern vehicle safety features.

While it is evident that the likelihood of serious injuries still exists at this speed, particularly with reckless driving or other adverse circumstances, the 90% survival rate reflects the broader context of pedestrian safety research. Therefore, this statement is accurate in conveying the estimated survival proportion at that speed, illustrating the role speed plays in pedestrian impact outcomes.
