Sonoma police have issued a warning to Valley motorists – put down the cell phone, keep your eyes on the road and both hands on the wheel.

Throughout the month of April, officers on patrol will be targeting distracted drivers, particularly those using cell phones in defiance of the law.

An incomplete count as of Friday, showed police had ticketed 19 drivers for talking on their mobile phones, at least 10 drivers for texting, and those were only preliminary numbers.

Sgt. Spencer Crum, of the Sonoma Police Department, said the count will rise dramatically as records are updated, and he encouraged motorists to respect the law, which makes it illegal for anyone under 18 to use a cell phone in a car, even hands-free. Drivers over 18 can be fined in escalating increments from a first offense of $20. Penalty assessments can more than triple the fine.
