No Texting, Email, IM or MMS While Driving Law in California Starts January 1, 2009

It's dangerous to text, talk or do anything with a wireless phone while driving. The National Highway Traffic Safety Administration has determined that driver inattention
is a primary or contributing factor in as many as 25 percent of all
police-reported traffic collisions and thousands of collisions that
aren't reported to the authorities.

Beginning January 1, 2009, texting while driving will be illegal in the
state of California.

The fine in California for texting while driving is $20 with added court costs and fees upping the total to be paid to reach as much as $90 depending on the county. The law also covers email and other electronic devices.

From the CA Department of Motor Vehicles Website:

Starting January 1, 2009 , writing, sending, or reading a text-based communication while driving
will be against the law for all drivers in California.

This new law applies to electronic wireless communications devices
used to manually communicate with any person using text-based
communication, including, but not limited to, communications referred
to as a text message, instant message, or electronic mail.

Violating this law is punishable by a base fine of $20 for a first
offense and $50 for each subsequent offense. With the addition of
penalty assessments, fines can be more than triple the base fine amount.

Texting is already banned  in six other states and the
District of Columbia.

17 states have laws banning "novice
drivers" (usually those under a certain age or with less than a full
driver license) from using a phone while behind the wheel.
