I was arrested for my first DUI in San Mateo County about 7.5 months ago. It was a single-vehicle incident with no injuries and no drugs involved.
The DA still has not filed criminal charges. I’ve checked the San Mateo County court system multiple times and there is still no case.
I’ve been handling the DMV side separately and I’m finishing those requirements, but I’m mainly wondering about the criminal case.
Has anyone here had a DUI in San Mateo County where the DA took 7+ months to file?
If so, how long after your arrest were charges eventually filed? Has anyone reached the one-year mark without charges being filed?
Mainly looking for recent San Mateo County experiences (2024–2026). Thanks!
