ESSEX, Ont. -- Ontario Provincial Police say a 55-year-old man has been charged after reporting himself for impaired driving.

Police say they got a call from a driver on Tuesday morning who told the dispatcher he was too drunk to drive.

OPP say the man told the dispatcher that he'd pulled onto the shoulder of Highway 3 in southwestern Ontario and would leave his four-way flashers on.

Police located the vehicle a short time later and discovered the driver still on the phone with OPP dispatch.

Officers allege an open liquor bottle was found in the vehicle.

The man is charged with impaired care and control of a motor vehicle and is to appear in court next month in Windsor, Ont.
