An electronic message includes, but is not limited to, e-mail, a text message, an instant message, a command or request to access a World Wide Web page, or other data that uses a commonly recognized electronic communications protocol. An electronic message does not include voice or other data transmitted as a result of making a phone call, or data transmitted automatically by a wireless communications device without direct initiation by a person.
(a) No person may operate a motor vehicle while using a wireless communications device to compose, read, or send an electronic message, when the vehicle is in motion or a part of traffic.
(b) A person who violates paragraph (a) a second or subsequent time must pay a fine of $225, plus the amount specified in the uniform fine schedule established by the Judicial Council.
This section does not apply if a wireless communications device is used:
(1) solely in a voice-activated or other hands-free mode;
(2) for making a cellular phone call;
(3) for obtaining emergency assistance to (i) report a traffic accident, medical emergency, or serious traffic hazard, or (ii) prevent a crime about to be committed;
(4) in the reasonable belief that a person's life or safety is in immediate danger; or
(5) in an authorized emergency vehicle while in the performance of official duties.
