Three people were transported to hospital following a two-vehicle crash at Highbury Avenue and Medway Road on Tuesday afternoon.
Emergency crews were called to the scene north of London around 2 p.m.
OPP say a black SUV was northbound on Highbury Avenue when it collided with red car that was westbound on Medway Road.
The red car was then pushed into a traffic signal pole.
A London woman in the red car was trapped and had to be extricated by firefighters. She was taken to hospital with serious, but non-life-threatening injuries.
The two women in the black SUV were also taken to hospital with non-life-threatening injuries. Both women are from St. Catharines, Ont.
Middlesex County OPP say an independent witness tells them it appeared the black SUV ran a red light before colliding with red car.
