Which of the following is a key duty of a Highway Patrol Officer?

Responding to traffic incidents is a key duty of a Highway Patrol Officer. This responsibility involves attending to accidents, providing assistance to drivers, ensuring the safety of the scene, and facilitating the flow of traffic. Highway Patrol Officers are trained to assess situations involving vehicles, pedestrians, and traffic regulations to mitigate hazards. They play a critical role in enforcing traffic laws, investigating crashes, and, when necessary, providing medical assistance or coordinating with other emergency services.

The other choices relate to duties more associated with different agencies or departments. Conducting city inspections is typically under the purview of municipal inspectors, while supervising park rangers is related to agencies focused on park management and conservation. Conducting fire safety education is generally part of a fire department's mission, focusing on prevention and education efforts regarding fire safety rather than law enforcement duties.
