SAN JOSE, Calif. (AP) — California drivers will be allowed to text when they’re behind the wheel of a car, as long as they’re using a hands-free device, and with some restrictions.

Under a bill signed into law by Gov. Jerry Brown on Friday, beginning Jan. 1, drivers will be able to send, dictate and listen to text messages, but only if they’re using a voice-activated device attached to a cellphone by a headset or Bluetooth earpiece, or a program inside a vehicle, like OnStar.
