What is one of the main responsibilities of the Arizona Highway Patrol?

One of the main responsibilities of the Arizona Highway Patrol is to enforce traffic laws and ensure safe travel on the highways and roadways across Arizona. This includes monitoring speed limits, checking for impaired driving, and responding to accidents. By actively enforcing traffic regulations, the Highway Patrol plays a critical role in promoting safe driving practices and reducing the occurrence of traffic-related incidents. This responsibility is fundamental to their mission of protecting the public and maintaining order on the streets, thereby contributing to overall roadway safety.

The other options listed relate to functions that are not typically under the purview of the Highway Patrol. For example, managing toll booth operations is generally handled by transportation departments or agencies, while vehicle registrations are a function of motor vehicle departments. Additionally, training emergency responders often falls within the scope of emergency management or fire departments, rather than the Highway Patrol's direct responsibilities.
