Greensborough Highway Patrol officers are appealing for public assistance after a multi-vehicle collision in Thomastown this afternoon.
Emergency services responded to reports of a collision between two cars and a truck outbound on the M80 Ring Road, between Edgars and Dalton roads, about 1.45pm.
It is believed, just prior to the collision, two unknown vehicles were driving erratically and collided with one another, causing the truck to swerve and collide with a Mazda BT50. The force of the collision caused the Mazda to lose control and collide with a Mitsubishi Pajero.
The two initial vehicles, described as small sedans, did not stop at the scene.
The driver of the Mitsubishi, a 35-year-old Essendon West woman, was transported to hospital for observation.
There were no other injuries.
Investigations remain ongoing and police are keen to hear from anyone who witnessed the collision or has dashcam to come forward.
Anyone who witnessed the collision, has CCTV or dashcam footage or anyone with information that could assist investigators is urged to contact Crime Stoppers on 1800 333 000 or www.crimestoppersvic.com.au.
