What is the main goal of speed limits?

The primary goal of speed limits is to enhance safety by regulating driving speeds. Speed limits are established based on various factors, including road conditions, traffic patterns, and surrounding environments, all aimed at ensuring the safety of drivers, passengers, and pedestrians. By setting a maximum allowable speed, these regulations help reduce the likelihood of accidents, as higher speeds are often associated with a greater risk of serious crashes. Moreover, adhering to speed limits contributes to better reaction times for drivers, allowing more time to respond to sudden changes in traffic conditions or obstacles on the road.

In contrast, the other options suggest motives that do not align with the fundamental purpose of speed limits. For instance, maximizing speed on highways or promoting faster traffic flow could lead to unsafe driving conditions, while restricting the number of vehicles on the road does not relate directly to managing individual driving behavior and safety. Hence, the emphasis on regulating speeds to enhance safety is crucial for maintaining order and protection on roadways.
