'WASHINGTON (CNN) -- Arrests for women driving under the influence jumped by nearly 30 percent during the decade ending in 2007, according to a study released Wednesday by the U.S. Transportation Department.
"To be honest with you, I was certainly surprised about that statistic," Transportation Secretary Ray LaHood said at a news conference.
However, when it comes to drunken driving arrests, women continue to be outnumbered by men by four to one.
The report, authored by the FBI for the National Highway Traffic Safety Administration, found a declining number of men arrested for similar alcohol-related violations.'

I'm not surprised in the least!
