Three Sonoma County police departments were honored recently by the state for their overall traffic safety programs and enforcement of traffic laws last year.

Petaluma police received first place among those departments with 51 to 60 officers, Santa Rosa earned second place among the 165 to 250 officer group and Sebastopol was second place among departments of 1 to 18 officers.

Petaluma also received a special award for the best impaired driving enforcement and education program in the state, an honor the department has earned for the last four years.

The awards are from the California Law Enforcement Challenge, which is overseen by the CHP and state Office of Traffic Safety. Departments submit information about their enforcement programs and traffic enforcement statistics, and the winning programs are those that combine officer training, public information and enforcement to reduce crashes and injuries, according to challenge officials.
