Lab employees may purchase AC Transit and BART tickets from the Tripmobile -- a "store on wheels" operated by the Berkeley TRIP commuter store. The Tripmobile drives to Berkeley Lab during lunch time the first Thursday of every month. By buying tickets from the Tripmobile, employees may deduct up to $65 of their public transit costs from their pre-tax paychecks every month through a new program of commuter tax incentives.
