"I did check it, so I don't want (my information) on the list they sell. But I guess it'd be nice if they clarified it a little bit," said Darren Gray, a Wisconsin driver.

When people go to the DMV to get or renew their driver's license, the form will ask them if they would like to have their name/address withheld from the lists the department sells. If people don't remember if they checked this box or would like to now opt out, they can find more information at http://www.dot.state.wi.us/drivers/optout.htm.
