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

The option indicating increased insurance costs is recognized as a secondary impact of traffic incidents because such events often lead to higher claims and premiums for individuals and businesses involved. When an accident occurs, insurance companies may need to pay out for damages or medical expenses, which can subsequently raise the overall costs for all insured drivers in the area. This creates a ripple effect beyond just the immediate parties involved in the incident, affecting the larger pool of policyholders who may experience increased premiums as a result.

The other options reflect initiatives or changes that do not necessarily arise as direct consequences of traffic incidents. For instance, enhanced roadway infrastructure and formal traffic education programs may result from broader traffic safety initiatives or planning, rather than being direct secondary impacts of a specific traffic accident. Similarly, the expansion of public parks is unrelated to the consequences of traffic incidents and does not arise as a byproduct of such events.
