NASHVILLE (AP) — First Lady Crissy Haslam is preparing to celebrate the children's awareness campaign of Governor's Highway Safety Office.

The Tuesday event will commemorate mascot Ollie the Otter making a presentation to the 400,000th child in the program's history.

The character-driven program aimed to increasing booster seat and seat belt usage has visited more than 23,000 classrooms in the last five school years.

More than 1,000 volunteers in the fields of law enforcement, emergency repose, education and community health have been trained in the program.

Tuesday's event is scheduled to be held at the New Hope Academy in Franklin.
