California Highway Patrol (CHP): Understanding Their 911 Response and Traffic Enforcement Responsibilities

California Highway Patrol (CHP): Understanding Their 911 Response and Traffic Enforcement Responsibilities

The California Highway Patrol (CHP) is a specialized police agency responsible for traffic law enforcement and accident investigation on the state highway system. While their primary duty revolves around traffic matters, they also respond to various emergency calls through 911 services. This article aims to clarify the extent of CHP's response to 911 calls and their overall enforcement responsibilities.

CHP's Role in Traffic Enforcement and Emergency Calls

When an officer in the field needs assistance, the CHP dispatch center is always ready to respond to their call for help. Additionally, members of the public can call 911 in emergencies or suspicious activity related to traffic laws and safety. Although a significant portion of their work involves tickets, handling drunk drivers, and addressing traffic accidents, the CHP does respond to a wide range of calls that come in through emergency services.

Most accidents are reported through the 911 system, and the CHP is often the first to hear about them. If they are active on the right frequency and the call relates to traffic issues, they are duty-bound to respond. This ensures prompt assistance and support for other officers on the scene. However, their jurisdiction is crucial in determining whether they or another agency responds to a specific call.

Call Jurisdiction and Response Authorities

The CHP is a fully empowered police agency specializing in traffic law enforcement and accident investigation on the state highway system. They are responsible for traffic concerns in unincorporated areas, and they also protect state buildings. For instance, if an automobile collision occurs in an unincorporated area of Pasadena, CA, the CHP is responsible for responding and investigating the incident. In contrast, if the same collision happens inside the city limits of Pasadena, the Pasadena Police Department (PD) would handle it. Similarly, if a crime such as a robbery takes place in the unincorporated area of Pasadena, the Los Angeles County Sheriff's Department (LASD) would respond and manage the situation.

It's important to note that the CHP does not typically respond to 911 calls in LA County if they are not the closest unit or do not have jurisdiction. In such cases, local police departments or sheriff's offices may contact the CHP dispatch center for assistance. The CHP can also be called upon to shut down a freeway offramp or to deal with incidents at DMV offices, but usually, it's the local PD or sheriff’s department that initiates contact with their dispatch center.

However, in rural areas where the CHP and the county sheriff are often the only law enforcement officers present, they frequently provide backup for each other. This collaboration ensures that both agencies can effectively manage emergencies and crimes in their respective jurisdictions.

CHP's Empowerment and Responsiveness

CHP officers are fully sworn and empowered law enforcement officers, equipped with badges and armed. In some situations, if they are the closest law enforcement officers available, they will answer 911 calls for any type of crime, serving as a backup for local police departments or sheriffs' offices. This dual role ensures that the public can always rely on CHP for prompt and effective response to emergencies and traffic-related incidents.

Understanding the CHP's responsibilities and their jurisdiction can help the public better navigate emergency situations and know whom to call based on the nature of the incident. Whether it's a collision on the highway or a crime in an unincorporated area, the CHP is there to protect and serve the public in their unique capacity.
