Which of the following refers to measures that prevent accidents on roadways?

Traffic safety encompasses a variety of strategies and actions designed to reduce accidents and enhance the overall safety of roadways. This concept includes the implementation of regulations, the design of road infrastructure, the enforcement of traffic laws, and the use of educational programs. Each of these measures is critical in preventing accidents, as they focus on improving driver behavior, vehicle safety, and the condition of roads.

Community engagement, while important for fostering relationships between law enforcement and the public, does not directly pertain to accident prevention measures on roadways. Similarly, law enforcement, while a component of traffic safety, is a broader category that includes maintaining order and enforcing laws beyond just accident prevention. Public awareness campaigns serve to inform and educate the public about safe driving practices but are part of the larger traffic safety framework rather than the encompassing term itself. Thus, traffic safety is the most comprehensive and accurate choice in addressing measures specifically aimed at preventing accidents on roadways.
