At 40 MPH, what percentage of pedestrians survive an impact with a vehicle? 90% 50% 10% None of the above

Analysis of the Problem

The question asks for the percentage of pedestrians that survive an impact with a vehicle traveling at 40 MPH. To answer this, we need to understand the relationship between vehicle speed and pedestrian survival rates.

Relevant Concepts

Various studies and statistics provide insights into pedestrian survival rates at different speeds. Research indicates that as vehicle speed increases, the likelihood of pedestrian survival decreases significantly.

Overview of Survival Rates

1. At 20 MPH: The survival rate is around 90%.
2. At 30 MPH: The survival rate drops to about 50%.
3. At 40 MPH: The survival rate can be as low as 10% or even less in certain circumstances.

Final Answer

At 40 MPH, the percentage of pedestrians who survive an impact with a vehicle is approximately 10%.
