Lindsay Lohan mug shot launches drunk driving ad

A U.S. restaurant and liquor group used a mug shot of troubled actress Lindsay Lohan on Friday to launch a national campaign against the use of new technology aimed at keeping drunks off the road.

A full page advertisement in the newspaper USA Today used the police shot of Lohan after her arrest in Los Angeles last year for drunken driving under a caption saying "Ignition interlocks. A good idea for:" (Lohan) "But a bad idea for us:" showing pictures of adults drinking at weddings and restaurants.

The ad says ignition interlocks, which prevent intoxicated drivers from starting their cars, are "a great tool for getting hard-core drunk drivers off our roads."
