OK SB1027

Prohibits operating a motor vehicle on public roads while using a wireless telecommunication device to write, send, or read text messages, instant messages, or emails

Exempts law enforcement officers, firefighters, emergency vehicle operators performing official duties, and physicians communicating for medical emergencies or patient care

Allows use of wireless devices for reporting illegal activity, summoning emergency help, preventing injury, relaying information between transit operators and dispatchers, and GPS navigation

First violation carries a fine up to $175; subsequent violations up to $500; fines double if the driver is involved in a crash at the time of violation

Enforcement is secondary only, meaning officers cannot stop a vehicle solely for texting while driving; violations count as moving violations
