New Posse Radar Trailer The Sheriff's Posse of Sun City serves as the “eyes and ears” of the Maricopa County Sheriff's Office. We do not have law enforcement authority and are not permitted or equipped to make traffic stops or issue speeding tickets. That does not mean that we can't assist the Sheriff's deputies in attempting to control speeding on the streets of Sun City. The visibility of our marked patrol cars is frequently enough to get people to slow down as they travel through our community. Even more effective may be our radar speed monitoring trailer, which most people have probably seen placed at various locations throughout our community. This device has a large digital display which shows the speed of the approaching vehicle as compared to the posted speed limit. More than just displaying the speed, the unit also accumulates data and produces reports showing the number of vehicles and the speed at which they travel past a certain point over a period of time. We then provide this information to the Sheriff's deputies so that they know where to concentrate their traffic enforcement efforts. This radar unit has proven to be so useful that the Posse has recently purchased a second radar trailer at a cost of over $8000. We will now be able to double our effort to control excessive speed here in Sun City. If you know of an area where you feel traffic needs to slow down, call the Posse at 623-972-2555 to request the placement of one of our radar trailers. The Sheriff's Posse of Sun City is an all volunteer organization which has been serving Sun City since 1973. We receive no funding from any government source. All of our financial support comes from the gratitude and generosity of the people of Sun City.
