It's illegal in California to use a cell phone while driving unless it's hands-free.
It's also illegal to text while driving.
But last year, legislators made an exception… to allow texting while driving if using new voice-operated cell phone technology.
Democratic Assemblymember Jim Frazier says it was a mistake.
He says new studies show chances of a crash using that technology are eight times greater than a driver who is not texting while driving.
He says he thinks lawmakers will change their minds.
Frazier: "When they see the studies that are out there, we firmly believe that given that information our colleagues will understand what we're trying to accomplish."
Frazier says he has support from the National Safety Council and law enforcement agencies.
