(Lake County, IN) - A party bus took rock and roll to another level on I-65 Thursday.

A charter tour bus tipped over after taking evasive action in Lake County near Lowell just after 9:00 Thursday morning.

According to State Police, the driver of the northbound party bus did not notice traffic slowing down ahead. Swerving to avoid a pile-up, the driver hit a semi as well as about 75-feet of guardrail before rolling onto its side.

Police did not say how many passengers were in the bus, but they all refused medical treatment at the scene. Interstate traffic was interrupted for several hours as the bus was uprighted and towed away and debris from it was collected.
