It’s not possible to know from cell phone records if the driver was typing, reaching for the phone or reading a text at the time of the crash, but it’s clear he was manually, cognitively and visually distracted, she said.
“Driving was not his only priority,” Hersman said. “No call, no text, no update is worth a human life.”
The board is expected to recommend new restrictions on driver use of electronic devices behind the wheel. While the NTSB doesn’t have the power to impose restrictions, it’s recommendations carry significant weight with federal regulators and congressional and state lawmakers.
Missouri had a law banning drivers under 21 years old from texting while driving at the time of the crash, but wasn’t aggressively enforcing the ban, board member Robert Sumwalt said.
“Without the enforcement, the laws don’t mean a whole lot,” he said.
Investigators are seeing texting, cell phone calls and other distracting behavior by operators in accidents across all modes of transportation with increasing frequency. It has become routine for investigators to immediately request the preservation of cell phone and texting records when they launch an investigation.
In the last few years the board has investigated a commuter rail accident that killed 25 people in California in which the train engineer was texting; a fatal marine accident in Philadelphia in which a tugboat pilot was talking on his cellphone and using a laptop; and a Northwest Airlines flight that flew more than 100 miles past its destination because both pilots were working on their laptops.
