A Mandurah woman has been taken to hospital after a three-car crash on Tuesday afternoon.
About 12.25pm, two cars had slowed down along Mandurah Road to cater for a lorry that had pulled out from a side street.
A third car then collided into the rear of the cars.
St John Ambulance took the woman, in her 20s, to Peel Health Campus as a precautionary measure.
Two cars were removed from the scene by tow trucks, while the other was able to drive away.
The incident forced emergency services to close the north lane of Mandurah Road.
