Last week, Berkeleyside spent a couple hours with the California Highway Patrol to get a sense of what a normal day on I-80 is like for these officers. There are about 100 officers with the Oakland CHP branch, and they handle the freeways from the southern Oakland border up through Berkeley until Richmond.

Carpool violations, cellphone violations, moving violations: most of the stops fell into these categories. During the ride-along we asked readers to send in questions over social media and Officer Sean Wilkenfeld, spokesman for the local office, provided answers. What does the CHP do about carpool violators, and what can other motorists do? What are the rules about lane splitting and what’s the weirdest call he’s been on? What are the penalties for carpool violation tickets, and what kind of excuses do people give when they get pulled over?

The day ended with a glimpse into a long tunnel that runs beneath the freeway, and a look at vehicles involved in fatal crashes. The Storify post that follows sums it up.
