Beginning Tuesday morning, California drivers under 18 are forbidden from using a phone while driving. Drivers over 18 must use a hands-free device. I'm sure plenty of Valley wheeler-dealers will risk the $20 first-offense fine as "the cost of doing business." How very entrepreneurial of you. Since using a phone raises your risk of an accident to the same as driving drunk, why not crack a flask of Crown Royal while you're at it? It'll make the accident a lot less painful.
