Officials hope to reduce the number of deaths and injuries among children and young adults in the county.
The training started on Tuesday and has included a series of topics, including vehicle technology and the different kinds of seats and rules associated with them.
The training wraps up Friday, ahead of a child safety seat check-up event Saturday.
"We were seeing that we weren't doing our jobs as a county," said CHP Hanford Area Officer John Tyler. "Our kids were getting killed, and the number one reason was motor vehicle traffic collisions and we know that a properly installed car seat will prevent those fatal injuries and reduce the severe injuries so these kids can survive these car crashes."
Saturday's event is from 9 a.m. to noon at the Kings County Health Department, on Campus Drive and Lacey Boulevard in Hanford. Officials say they'll spend 20 to 30 minutes with each family who attends.
