Stanford’s Department of Public Safety does issue bike citations for non-compliance. The estimated citation for not stopping at stop signs is approximately $200+. You can be cited for not stopping at stop signs, not having a front bike light, having both ears covered while riding (e.g., iPod in both ears) and not having your bike registered, among other violations. If cited, you have a one-time option in an 18-month period to attend the free bike safety class/bike citation diversion class in lieu of paying the fine. You can register online for the bike safety class.
