About the author →
El Cajon sits in the East County valley where Interstate 8, State Route 67, and State Route 125 funnel traffic between San Diego, the desert, and the foothill communities. That freeway geography, paired with a dense commercial corridor along Main Street and El Cajon Boulevard, shapes how impaired-driving cases are made here — and which agencies make them.
How DUIs are policed in El Cajon
Inside the city limits, the El Cajon Police Department is the primary agency that investigates impaired driving. Its traffic unit runs both DUI/driver's-license checkpoints and DUI saturation patrols — typically funded through grants from the California Office of Traffic Safety (OTS) and routed through the National Highway Traffic Safety Administration. Checkpoint locations are generally selected based on a history of DUI collisions and arrests, and the department publicizes upcoming operations in advance, which is consistent with the "high-visibility enforcement" model agencies across California use as a deterrent.
El Cajon's OTS city profile reflects a city that carries a high overall volume of traffic collisions for its population, with alcohol-involved crashes making up a meaningful share of that total (DRAFT — verify the current year's El Cajon rankings and figures directly at ots.ca.gov; OTS groups cities by population and reports separate ranks for alcohol-involved collisions and DUI arrests, and these numbers change year to year). The practical takeaway is general but reliable: El Cajon is an active DUI-enforcement city, so a stop, a checkpoint contact, or a collision investigation can quickly turn into a chemical test and an arrest.
On the freeways and the surrounding unincorporated East County, the California Highway Patrol's El Cajon Area office handles DUI enforcement on I-8, SR-67, SR-125, SR-52, SR-94, and the region's other state routes. A DUI arrest near El Cajon can therefore come from either El Cajon PD (city streets) or CHP (freeways and county roads) (DRAFT — confirm the arresting agency on the specific report) — a detail that matters, because it affects which officers testify and how the stop and testing were documented.
- El Cajon Police Department — DUI checkpoints and saturation patrols on city streets, often OTS-grant funded

- Checkpoint sites are generally chosen from prior DUI collision and arrest history; operations are publicized in advance
- El Cajon's OTS profile shows high overall collision volume with a notable alcohol-involved share (DRAFT — verify current rankings at ots.ca.gov)
Who prosecutes an El Cajon DUI — and where
El Cajon does not have its own criminal prosecutor for DUI. The City of San Diego is the only city in the county with a city attorney that prosecutes misdemeanor DUI; everywhere else in San Diego County — El Cajon included — both misdemeanor and felony DUI are prosecuted by the San Diego County District Attorney. (El Cajon does have a City Attorney's office, but it handles municipal-code and civil matters, not criminal DUI prosecution.) Fittingly, the DA's East County branch is based in El Cajon itself and covers more than twenty East County communities (DRAFT — confirm the charging division for the specific case).
An El Cajon DUI case is heard at the East County Regional Center at 250 East Main Street in El Cajon — the East County hub of the San Diego Superior Court, which handles the area's misdemeanor and felony criminal calendars. Ron Chini works from his Irvine office and travels to appear at the El Cajon courthouse and in San Diego Superior Court on behalf of his East County clients (DRAFT — confirm the assigned department and appearance dates for each case).

Does El Cajon run DUI checkpoints?
Yes. The El Cajon Police Department conducts DUI/driver's-license checkpoints and saturation patrols, often funded through California Office of Traffic Safety grants, and publicizes them in advance.

I was just arrested for DUI in El Cajon. What do I do first?
Act on the 10-day DMV deadline. A California DUI arrest triggers a separate DMV process, and you have only 10 days to request a DMV hearing or your license is automatically suspended. Calling a DUI attorney quickly protects both that hearing and your defense in court. See our DMV hearing guide.
Can Ron Chini defend my El Cajon DUI from Irvine?
Yes. Ron Chini's office is in Irvine, and he regularly handles San Diego County DUI cases, appearing in San Diego Superior Court and at the El Cajon courthouse on his clients' behalf. He is an experienced DUI defense attorney — he does not claim to be a certified specialist, and no result is ever guaranteed. The consultation is free, with flexible payment plans available.
