Hersman said the exceptions to this rule would be devices that assist the driver in getting to a destination and for use in emergency situations.
She said that this recommendation would also apply to communications technologies such as Bluetooth, but that the NTSB is not proving a list of "acceptable" devices for use in vehicles by drivers. The organization is leaving development of actual laws, and enforcement, up to the individual states.
"Our recommendation is to the states that pass and enforce the laws," Hersman said. "We're not looking at passengers being able to text and talk; we're looking at the safe operation of the vehicle by the driver. And yes, that applies to Bluetooth and hands-free technology."
In terms of enforcing such a ban, Hersman said she is confident law enforcement will be able to develop methods for doing so.
"Law enforcement is talented. They can recognize impaired drivers. They also can recognize when drivers are distracted," Hersman said. "Our law enforcement agencies deal with aggressive driving. I know they will be able to come up with ways to enforce these rules."
