AT A GLANCE

• The "World's Meanest Mom" put her drunk driving son's truck up for sale in the classifieds

• She's asking $3,500 or best offer for the 1993 Ford Ranger

• The ad in the Northern Wyoming News reads, "Son forgot to use his brain and got caught drunk driving" and asks interested parties to call the "meanest mother in Wyoming"

The meanest mother in Wyoming just may save her son's life.

A mom who caught her 16-year-old son drunk driving is now selling her son's car as punishment. In a classified ad for the car in her local newspaper, she calls herself the "meanest mother in Wyoming."

Short, clipped sentences in the classified ad for the 1993 Ford Ranger hint at the unnamed mom's distress. "VERY angry mother," the ad in the Northern Wyoming News reads. "Son forgot to use his brain and got caught drunk driving."

She's asking $3,500 or best offer for the vehicle, and asks interested parties to call the "meanest mother in Wyoming."AOL Autos reached out to her at the number listed seeking comment, but her mailbox is full.

The mom has substantial reason to be worried. Although it's on the decline, underage drinking is still lethal to approximately 5,000 people each year, according to Mothers Against Drunk Driving.

"So it's understandable that a mother would be upset with her child for drinking underage and then choosing to get behind the wheel," MADD national president Jan Withers said.
