HARRISBURG – The PA Turnpike Commission is starting to remove or cover up the red, yellow, and green lights that indicate if a driver’s E-ZPass has been properly read. Officials said the decommissioning started at the Harrisburg West interchange and will continue though the calendar year. Federal guidelines now prohibit their use. The turnpike says more modern toll equipment is being installed, and as part of that it’s adopting the federal guidelines. The red, yellow, and green lights at interchanges have been in place since E-ZPass was started in 2001. The upgrade will be completed by the end of 2017.
