What is the purpose of speed limits?

The purpose of speed limits is fundamentally tied to ensuring safe driving conditions and reducing collisions. Speed limits are established to guide drivers on the maximum allowable speed under specific conditions, which helps to prevent accidents caused by excessive speeds that can reduce the driver's reaction time and increase the severity of crashes. By regulating how fast vehicles can travel, these limits play a crucial role in enhancing road safety for all users, including pedestrians, cyclists, and other motorists.

Speed limits are determined based on various factors, including road design, traffic patterns, and environmental conditions, all aimed at maximizing safety. Adhering to these limits helps create predictable driving conditions, allowing drivers to anticipate the behavior of others on the road and respond appropriately.

Other choices do not encapsulate the primary reason for speed limits as effectively. While they may touch upon related aspects, such as traffic flow or promoting specific vehicle types, the primary focus of speed limits is the safety and well-being of all individuals on the road.
