Medicine Hat Police continue to investigate an accident on Dunmore Road this afternoon.

Police say they first noticed a Buick driving erratically at slow speeds, and attempted to pull it over, but the driver appeared not to notice.

Officers then shut off emergency equipment hoping to reduce the potential of harm to the public.

The 58 year old female driver hit a handi-bus at the Dunmore Road and 22 Street SE intersection and the car then caught on fire.

Firefighters managed to quickly get the driver out, transporting her to hospital with serious injuries. Three police officers were treated for smoke inhalation.
