You can bring your lunch or groceries onto a train, just please don't eat it, he said. BART has a no eating or drinking policy in the Paid Areas in an effort to keep the trains and stations as clean as possible.

While you are physically allowed to carry food and beverages onto BART (Bay Area Rapid Transit) in San Francisco, you are strictly prohibited from eating or drinking while in the "Paid Area" of the system. This "Paid Area" includes everything inside the fare gates: the station platforms, the elevators, and the trains themselves. According to California state law and BART policy, consuming food or drink in these areas is an infraction that can result in a citation and a fine of up to $250, along with mandatory community service. The ban was implemented to maintain cleanliness and prevent pests, as well as to protect the system's electrical components from spills. You are welcome to eat and drink as much as you like in the "Free Area" outside the fare gates. In 2026, BART enforcement remains vigilant, especially regarding "stinky" or messy foods that can negatively affect the experience for other commuters. While most people are not ticketed for a discreet sip of water, carrying an open container or eating a full meal is likely to catch the eye of a BART police officer. For travelers, it is best to finish your snacks before you tap your Clipper card to enter the station.
