El Cerrito, California Roadblocks

I saw this roadblock on new years eve a few years ago. The signs said sobriety checkpoint. I drove through after they had ceased operations for the night (I think it was about 1:00 am), so I wasn’t stopped. I would expect to see checkpoints here on party holidays in the future. **I don’t know the regularity, what percentage of cars were being stopped, or whether they were checking for more than DUI. I checked the middle choices by default. The location is valuable enough to post.**
