Assembly Bill 313 was introduced by freshman Assemblyman Jim Frazier, D-Oakley.
State law currently prohibits drivers from texting with hand-held devices, but not those that operate on voice commands.
AB 313 would delete the existing exception for voice-controlled texting devices.
In its findings and declarations, AB 313 says that "there is no difference in the crash risk of hand-held or voice-operated devices. Furthermore, no study has determined that texting while driving is safe."
The bill also declares that distracted driving is a "dangerous epidemic" that killed 3,300 and injured more than 400,000 people nationally in 2011.
* Updated at 10:25 a.m. Wednesday to clarify that the bill would apply to California drivers.
