Either drivers in Sonoma County are getting better at obeying traffic laws or they're simply fed up with paying ever-increasing fines.
Those are just two theories about new data released by Superior Court officials that shows a whopping 30 percent decline in the number of tickets handed out in the first six months of this year.
"The price of tickets has gone up quite a bit," said CHP Officer Jon Sloat. "They are not cheap. You don't want to get one."
Between January and July, officers patrolling city streets, county highways and state roads from Petaluma to Cloverdale wrote 35,850 tickets for violations ranging from running stop signs to speeding. The previous year, they wrote 50,571 tickets over the same period.
Just what has triggered the change is anyone's guess.
The CHP said public education about dangerous driving is starting to pay off in a county with its share of high-profile fatal accidents. Also, near-continuous construction on the main artery, Highway 101, has forced people to slow down, Sloat said.
"It's lightened the load," Sloat said.
Another factor could be an awareness of rising fines. Each year, the state adds surcharges and other administrative fees to base fines. For example, an improper turn violation is $234 while a ticket for driving 26 mph over the speed limit is $480.
"It's about a third of my paycheck," said Greg Boitos of Santa Rosa, who got the latter fine about three years ago and was at the courthouse last week getting a copy of his driving record. "It's a hassle. And it's unnecessary if you are going the speed limit."
Still another cause could be staff reductions at police departments that have taken officers from the streets. Petaluma police Sgt. Ken Savano said his department is down to 68 officers from a high of 76 just a few years ago.
