Hamilton police are trying to figure out what caused a vehicle rollover in Stoney Creek early Sunday morning that sent the driver to hospital and injured his two passengers.

It happened around 4:47 a.m., police say, when police were called to Fruitland Road and the CN railroad overpass between South Service Road and Barton Street East.

A man was driving south on Fruitland Road when he lost control of the vehicle, left the road, hit a streetlight and rolled over.

The driver ended up with serious but non-life threatening injuries, and his two passengers also received minor injuries.

Police are now investigating, and are asking any witnesses who haven't talked to police to call the collision reconstruction unit at 905-546-4755.
