Lower speed limits can decrease accident severity because they provide drivers with more time to react to unexpected situations and reduce the impact of collisions. When vehicles travel at lower speeds, the kinetic energy is less, resulting in less severe accidents. This principle is supported by research indicating that as speed decreases, the likelihood of fatal injuries in a crash also decreases. Furthermore, lower speed limits encourage more cautious driving behavior, which contributes to safety on the roads.

The option regarding higher speed limits reducing travel time is not universally true, as the overall traffic flow can be impacted by various factors such as congestion or driver behavior. The statement about speed limits being solely determined by local laws is misleading because while local authorities do set specific limits, there are also state and federal guidelines that influence these decisions. Lastly, the idea that all states have the same speed limit regulations is inaccurate, as each state has the authority to establish its speed limits based on its own laws and conditions.
