How does increased speed affect crash severity?

Increased speed significantly impacts crash severity because the kinetic energy involved in a collision rises with the square of the speed. This means that as a vehicle travels faster, the amount of energy released in a crash is much greater, leading to more severe outcomes for everyone involved. Higher speeds reduce the driver's reaction time and the ability to maneuver effectively, increasing the likelihood of a crash and the force behind it.

Higher speed also tends to result in more extensive vehicle damage and higher injury risks for passengers, drivers, and pedestrians. The force of impact at greater speeds is not easily dissipated, which can translate to greater injuries and fatalities in severe accidents. Understanding this relationship between speed and crash severity emphasizes the importance of adhering to speed limits and adjusting speed according to road conditions and traffic.
