In California now if you are on a cell phone while driving and involved in a fatal accident you may be charged with a felony, and spend years in jail.
The threat of a $20 fine may not sway every California driver from using a hand-held cellphone when a state ban takes effect July 1, but a motorist who ignores the law and causes an accident could face huge civil judgments or even jail if fatalities result.
"If you cause a fatal accident and you are running a stop sign, speeding or crossing a double line, any additional violation would add to the possibility a manslaughter charge could be filed," said W. Scott Thorpe, chief executive of the California District Attorneys Assn. "It all goes to state of mind and your recklessness."
