Traffic DivisionDedicated To Your Safety

The primary function of the Traffic Division is to facilitate the safe and effective movement of traffic through the City of Rancho Cucamonga. The Traffic Division enforces California Vehicle Codes, investigates traffic collisions, directs traffic when needed, and develops driver awareness of traffic laws and the causes of traffic collisions.

The Rancho Cucamonga Police Department Traffic Division consists of a sergeant, deputies, and service specialists. Currently they utilize motorcycles, traffic service trucks, patrol cars, and a commercial enforcement vehicle.

  • Responsible for the effective deployment of available resources to known problem areas as well as to areas where statistics project problems may occur.

  • Supervise the Major Accident Investigation Team. (MAIT)
  • Responsible for acquiring and overseeing traffic related federal grants.

Traffic Division Deputies

  • Deputies are primarily responsible for investigating traffic collisions and enforcement of traffic laws. There are currently ten deputies assigned to enforce traffic laws on motorcycles; six in cars, two of those dedicated to “driving under the influence” enforcement.
  • They work closely with the city traffic engineers and other agencies/departments in identifying potential problems with regards to traffic flow. Using Community Oriented Problem Solving (COPS) concepts, they direct available resources to resolve any potentially hazardous situation.
  • The use of motorcycles in the City allows faster response by officers to traffic collision scenes. The motorcycles can easily navigate through congested streets and arrive at the traffic collision before a patrol car could. The motorcycle officers can then coordinate resources for the protection of the people involved.
  • Motorcycle Officers are tasked with enforcing the vehicle code. The primary focus of enforcement is to prevent injury traffic collisions. The enforcement areas are identified using statistical data from recent traffic collisions. A secondary enforcement response was a result of citizen complaints over safety concerns.
  • Two deputies are assigned to the Driving Under the Influence (D.U.I.) unit. They are responsible for the aggressive prosecution of DUI drivers. DUI drivers will be actively sought out as a hazard to the community.

Service Specialist

  • The Service Specialist’s primary duty is investigating non-injury traffic collisions. This enables traffic deputies to remain free to conduct enforcement activities and to respond to higher priority calls for service. 
  • The Service Specialist has a myriad of secondary duties. These include abandoned vehicle abatement, parking code violations including; handicapped, fire lane, red curb, fire hydrant, and so on. They are relied upon to direct traffic at traffic collision scenes or other major incidents.
