It was the first text sent on the new system in Allegheny County, Pennsylvania, which is the fifth county in the U.S. to offer the 911 texting option. In Pennsylvania, texting while driving has been illegal since March 2012. “This is one that probably should have been better served by a phone call,” Downs said. The first county to offer 911 texting was Dauphin County (also in Pennsylvania) and in the seven months they have offered the service (it is offered for Verizon customers only), Emergency Management Director Steve Libhart said they have only received one real emergency text.
