Ongoing traffic concerns and issues can be brought to the attention of our Traffic Division by calling (909) 477-2800. Some examples of ongoing traffic concerns are; a high volume of vehicles running red lights, stop signs, speeding in residential areas, vehicles parking in areas designated only for loading and unloading near schools, vehicles using a public roadway for speed contests (or races), etc.
If you have a problem with one specific vehicle or person such as a neighbor, parking issue, etc., please contact our non-emergency dispatch at (909) 941-1488 at the time the violation or traffic problem is occurring so that an Officer/Deputy can respond. Rancho Cucamonga Police Officers cannot issue citations or speak to drivers about violations based on hearsay or for violations the Officer did not witness themselves.
Also, due to staffing and the need to respond to in-progress or possible injury or emergency calls for service; the Rancho Cucamonga Police Department normally is not able to "post an Officer" at a certain location to wait for a violation that one person has reported as occurring.
Ongoing traffic concerns are handled on a case by case basis, please contact our Traffic Division at (909) 477-2800 if an ongoing traffic problem is occurring in the City of Rancho Cucamonga.
