A mock car crash, involving local police, fire and medical personnel, will be staged at the Shakopee High School parking lot on Wednesday morning.

The event, scheduled from 9 to 10 a.m., is sponsored by the school’s Students Against Destructive Decision. It will be followed by a presentation in the auditorium to show students the dangers of drinking alcohol and driving.

The mock crash will not affect traffic. In case of inclement weather, it will be rescheduled to the same time Thursday.
