What key factors contribute to roadway safety according to the CHP?

The key factors that contribute to roadway safety according to the California Highway Patrol include elements that directly impact how vehicles operate on the road and how drivers interact with one another and their environment. Driver behavior is crucial, as it encompasses actions such as obeying traffic laws, being aware of surroundings, and avoiding distractions. Vehicle condition is also significant; properly maintained vehicles reduce the likelihood of malfunctions that could lead to accidents. Additionally, road design contributes to safety through features that facilitate smooth traffic flow and minimize hazards, while weather conditions can greatly affect visibility and traction, influencing driving behaviors and risk levels.

The other options do not encompass these critical safety aspects. The number of traffic lights might regulate traffic flow but does not necessarily reflect the overall safety of the roadway. Similarly, while public transportation availability can affect roadway traffic congestion, it does not directly account for the safety of vehicles when utilizing the roads. Traffic ticket prices may influence driver behavior to some degree, but they do not inherently relate to the fundamental factors that ensure safety on the road. Thus, the comprehensive answer highlighting driver behavior, vehicle condition, road design, and weather conditions provides a holistic view of what affects roadway safety.
