In December, the National Transportation Safety Board recommended that states ban drivers from using their cell phones in any way while operating a car.

In its report, the NTSB cited an Aug. 2010 accident that killed two people and injured at least 50 others. The crash took place on Interstate 44 near Gray Summit, Mo.

When the head of the National Transportation Safety Board called for states to pass tough new laws banning drivers from using cellphones or hand-held devices, she said: "No call, no text, no update, is worth a human life."

While Tuesday's statement by NTSB Chairwoman Deborah Hersman is undeniable, there are those who question the advisability of such a ban. Some state lawmakers and transportation experts say it could be difficult to enforce and that there's no real evidence yet that existing laws on hand-held devices have significantly reduced accident rates.

Federal accident investigators recommended states ban the use of cell phones and other electronic devices by all drivers except in emergencies.
