Sanilac County authorities are investing a Monday afternoon crash on Van Dyke Road. The Sanilac County Sheriff says a pickup truck driven by a 58-year old Cass City man was heading north on M-53 when he crossed the center line and struck a fuel tanker truck. The driver of the semi saw the pickup truck crossing the center line and was able to avoid a head-on collision and instead side-swiped the pickup. The tanker truck was empty at the time of the accident and alcohol is not believed to be a factor. Cass City EMS responded to the scene of the crash and investigations continue.
