At what speeds do most crashes causing injury typically occur?

Answer: C — Less than 40 miles per hour

Most crashes causing injury typically occur at speeds less than 40 miles per hour. Research has shown that many accidents, especially those involving pedestrians or cyclists, can happen in urban settings where lower speeds are common. At speeds below 40 miles per hour, the likelihood of sustaining serious injuries increases significantly due to the dynamics of the collision and the forces involved. While crashes can and do occur at higher speeds, most severe injuries and fatalities are more commonly associated with lower-speed impacts, particularly in residential areas or during low-speed maneuvers such as turning or parking. Focusing on speed limits and awareness at lower speeds is critical for enhancing safety and reducing the severity of injuries in accidents.
