Two years before her arrest on suspicion of driving under the influence, Lindsay Lohan taped a PSA warning about the dangers of driving drunk.

In one of the takes posted on TMZ.com, Lohan laughs after a member of the pop group A Simple Plan says "please don't drink and drive."

Lohan ends the PSA by saying "be safe" and giving the peace sign.

Lohan is now in rehab. Her father tells E! she's being treated for a problem with alcohol and the painkiller OxyContin.
