Car hitting Perth bus caught on dashcam

Dashcam footage has captured a Perth driver's car colliding with a bus while she was attempting a U-turn.

The accident was filmed by Matthew Thompson as he was driving behind the car on Wednesday afternoon on the Causeway in East Perth.

"Right before it happened I noticed she had her indicator on and wondered what she was doing," he told AAP.

He said the driver was in shock after the accident and he pulled up behind her to check she was OK.
