The Langley RCMP is investigating the cause of a rollover crash involving a classic car Tuesday evening. 

The driver, of what appears to be a 1955 Chevrolet Bel Air, lost control of the car near 238th Street and 54-A Avenue around 8 p.m.

Two people were inside the car when it flipped over. 

Mounties say they believe the owner of the car was in the passenger seat at the time of the crash and had been conducting engine tests throughout the day. 

Both occupants were rushed to hospital with non-life threatening injuries.
