the tickets along the northeast extension of the pennsylvania turnpike were originally handed out by person. in 1987, machines started to replace humans in distributing tickets. in 1990, an electronic toll collection system was proposed for the pennsylvania turnpike, where a motorist would create an account and use an electronic device that would be read from an electronic tollbooth. the motorist would be billed later. the multi-state electronic tolling system, which was to be called e-zpass, was planned to be implemented by 1998. the planned installation date was later pushed back to 2000. on december 2, 2000, e-zpass debuted along the northeast extension of the pennsylvania turnpike between mid-county and lehigh valley. on december 15, 2001, e-zpass was extended to include the entire length of the northeast extension of the pennsylvania turnpike. commercial vehicles were allowed to start using e-zpass on december 14, 2002.
