Which of the following is considered a secondary impact of traffic incidents?

In the context of traffic incidents, a secondary impact refers to the consequences that arise as a result of the primary incident, which typically includes injuries, fatalities, and immediate disruptions to traffic flow. The selection of increased insurance costs as the correct answer aligns with this definition because traffic incidents often lead to financial repercussions for individuals involved, including higher insurance premiums as a result of claims or accidents.

When a traffic incident occurs, it can have a ripple effect on the insurance industry, leading to increased costs for drivers due to claims associated with vehicle repairs and medical expenses. This trend contributes to heightened premiums for many drivers, reflecting the long-term economic impact of the incident beyond the immediate scene of the crash.

The other options reflect positive or unrelated outcomes. Enhanced roadway infrastructure, for instance, may occur due to a need for improvements but is not a direct consequence of a traffic incident; it is more of a proactive response to systemic issues within the roadway system. Similarly, formal traffic education programs and the expansion of public parks would not typically be considered direct or secondary impacts of traffic incidents; instead, these are broader initiatives that may stem from various community needs and safety considerations, rather than the aftermath of an accident specifically.
