There will be a number of police and fire trucks on the Bethel Schools campus today.  High School students will be participating in an assembly of a mock car crash to demonstrate the impact of driving under the influence.  The purpose of this advisory is to raise awareness.  Local first responders will be simulating an actual accident response.  Along with Bethel Police and Fire, New Milford, Danbury and the Redding Police Department will be on site.  Students have arranged for Life Star to do a flyover as part of the presentation.
