What is true about speed limits on highways?

Higher speeds generally contribute to more deaths and severe injuries due to the increased force and momentum involved in collisions at higher velocities. The relationship between speed and the severity of crashes is well documented; as speed increases, the likelihood of fatal outcomes also rises. This is because higher speeds reduce reaction time, make it harder for drivers to maintain control, and increase the distance required for vehicles to come to a complete stop.

Speed limits are established not just as arbitrary numbers, but based on extensive research and studies that assess road conditions, traffic patterns, and safety statistics. While lower speed limits in residential areas are designed to protect pedestrians and reduce accidents, an increase in speed limits on highways reflects a balance between road design, traffic flow, and safety consideration. However, exceeding these limits can significantly elevate the risk of severe outcomes in the event of a crash.
