Perth woman almost eight times over limit

A 30-year-old woman who crashed into a median strip while exiting Perth's Kwinana Freeway recorded a blood alcohol reading almost eight times the legal limit.

A member of the public, seeing she was drunk, removed the keys from her car's ignition and called police after seeing the collision at the Farrington Street exit in Leeming on Wednesday afternoon.

The woman blew 0.404 in a breath test and her driver's licence was immediately cancelled. She will also be charged by summons.
