As of next Monday, Massachusetts Bay Transportation Authority train and bus drivers will be banned from carrying cellphones or other electronic devices of any kind while operating T vehicles.
Drivers found using cellphones face an automatic 30-day suspension and recommendation for discharge. Drivers found with a cellphone in their possession face a 10-day suspension.
The new policy announced Wednesday follows last week's Green Line collision near Government Center that injured almost 50 people. Officials say one of the T drivers admitted to texting his girlfriend at the time of the crash.
The new cellphone ban is the strongest of any major transit authority in the nation. The state already banned its transit operators from using cell phones.
Transportation Secretary James Aloisi said the policy is designed to avoid a repeat of "the error of judgment" that led to Friday's accident.
Meanwhile, the driver is refusing to speak to federal investigators about the accident.
Peter Knudson, spokesman for the National Transportation Safety Board, says officials had a signed subpoena to serve 24-year-old Aiden Quinn, but his lawyer has advised him not to speak.
"However, Mr. Quinn did speak with others shortly after the accident and indicate that he had been texting shortly after the accident, so that's going to be [something], obviously, that we're going to consider in our report," Knudson said.
The NTSB has already submitted a request to access Quinn's phone records. Quinn's lawyer did not return calls for comment.
