Checkpoints are legal only when they follow the rules. We check whether yours did.
The short answer. DUI checkpoints in East County are legal when they follow strict rules set by California courts: neutral stopping criteria, advance public notice, supervisory oversight and a safe, non-arbitrary operation. If the checkpoint or the officers went outside those limits, evidence can be challenged or excluded.
Checkpoint cases often hinge on whether the checkpoint was operated legally and whether the contact and investigation stayed within proper limits. At a checkpoint you must stop and provide your license, registration and insurance, but you are not required to answer investigative questions beyond identification.
| When | What happens | What we do |
|---|---|---|
| Day of arrest | Checkpoint contact, investigation, arrest | You call us; avoid statements on the scene |
| Within 10 days | The DMV hearing window | We request it and review the paperwork |
| Evidence review | Operational plan and officer reports requested | We review the setup and the escalation |
| Resolution | Suppression motion, negotiation or trial | Leverage from any violations found |
We review whether the checkpoint was run legally from the start: the operational plan, officer staffing and supervision, signage and lighting, location and timing, and how drivers were selected and screened. If the setup or the officer’s actions exceeded lawful limits, we can file targeted motions to suppress evidence and challenge the detention, the arrest and any breath or blood testing.
