Such old news ... why state the obvious! If you're going to translate and inform, translate and inform properly and completely. Otherwise it's just swiping half an ass after a No. 2

The Wireless Communications Device Law (effective January 2009) states NO DRIVER in California may write, send, or read text messages while behind the wheel.

The Handheld Wireless Telephone Laws (effective July 2008) state:

1) California drivers may NOT use a wireless telephone while driving at any time, unless to make an emergency call to 911, law enforcement, or similar services.

... Drivers MAY utilize a “hands-free device" UNLESS they are under 18 years old
... Ear pieces/buds can be use, but only on one ear (as of 2016)
... Not applicable on private property!

If you are caught breaking these laws, you will be charged the following BASE FINES:

... 1st offense: $20, but realistically $76 after court fees and S&H
... 2nd offense and subsequent convictions: $50, but realistically $190 after court fees and S&H

In addition to these base fines, you can expect penalty assessments that can bring your overall cost to more than 3 times the amount of your base fine.
