Paper tickets need to be stamped/validated by using one of two ticket punches: mechanical (the tiny red machine near the driver - put a ticket in and pull the rear part towards you to punch it) or electromechanical (yellow or brown punch with a slot - insert your ticket and it will be stamped) or by swiping the Vilnius Citizen debit card at the yellow electronic readers. Validate your ticket immediately after boarding the vehicle.
