BART has a policy governing the use of Electric Personal Assistive Mobility Devices (EPAMDs) within the system. The policy covers all battery-powered, self-balancing, two-wheeled transporters, including the Segway Personal Transporter.
You must apply for and receive a permit in order to bring an EPAMD on BART. To apply for a permit, read the policy governing EPAMDs (.pdf), download the application for a general permit (.pdf) or a permit for persons with disabilities (.pdf) and follow the application instructions.
