A woman has been photographed smoking what appears to be a meth pipe while driving on the Kwinana Freeway.
A man witnessed the woman use a lighter to heat the bottom of the glass pipe as she was driving on the freeway southbound near Thomas Road on Saturday afternoon.
The witness said her car was swerving all over the road.
He then asked his wife to take a photo of the woman and her vehicle's registration plate.
Premier Mark McGowan told Seven News he was shocked by the photograph.
“One of the most insane things I’ve ever seen,” he said.
“Stupid crazy stuff. I look forward to police tracking her down and charging her.”
Police are investigating.
