California law requires handheld cell phone use while driving to be:

• A. You may hold and dial while driving.
• B. Texting is allowed if hands-free.
• C. Use a hands-free device; no holding or dialing while driving.
• D. You may use a headset only if traveling alone.

Answer: (C)

California requires using a hands-free device whenever you use a cell phone while driving. You should not hold the phone or dial manually; use Bluetooth, a headset, or the car’s built-in system and perform dialing with voice commands or after you’ve stopped if you must touch the device. Texting or composing messages is not allowed while driving, even with a hands-free setup. So the correct approach is to use a hands-free device and avoid holding or dialing while the vehicle is in motion.
