The patrol division is the backbone and most visible part of a law enforcement agency. Patrol is responsible for responding to calls for service from the public, including a rapid response to emergency situations. Some examples of a call for service include traffic crash investigations, reports of criminal activity, city ordinance violations, domestic violence, general complaints, traffic complaints, property disputes, suspicious persons, medical assistance, and many other social issues.
Additionally, traffic enforcement and preventive patrols are vital parts of patrol's responsibility. Traffic problems are an important issue being addressed by law enforcement today. This is mainly due to the large number of traffic fatalities, injuries, and the ever-increasing volume of traffic on our public streets and highways in the United States.
Preventive and highly visible patrol vehicles are instrumental in crime control and providing police services. The marked patrol unit provides accessibility by the public to law enforcement personnel and a rapid response to emergency situations.
