What is the purpose of speed limits?

Speed limits serve multiple important functions on the road, all of which contribute to better traffic management and overall safety. By regulating the flow of vehicles, speed limits help maintain a consistent pace among drivers, reducing the likelihood of congestion and enabling smoother traffic conditions. This systematic flow assists in minimizing bottlenecks and promotes an orderly environment for all road users.

Additionally, by establishing maximum speeds, speed limits aim to prevent accidents. When drivers adhere to designated speeds, they have more time to react to sudden changes in traffic, obstacles, or adverse road conditions. This fundamental principle of predictive driving plays a critical role in reducing collision risks.

Furthermore, speed limits are designed to enhance safety on roads not just for drivers, but also for pedestrians and cyclists. By setting appropriate limits based on the specific road conditions and environments, speed limits contribute to creating safer spaces for everyone.

Therefore, the collective impact of regulating vehicle flow, preventing accidents, and enhancing safety underscores the purpose of speed limits, making "All of the above" the most comprehensive answer.
