Tiger Woods Reportedly Won't Hire Driver Citing Privacy Concerns

7:15 AM PT Tuesday -- TMZ Sports obtained the arrest affidavit that shows Tiger Woods had two loose hydrocodone pills in his pocket at the time of his DUI arrest and stumbled through his field sobriety test.

Tiger Woods is addressing the question everyone is asking -- Why doesn't he get a driver, especially if he has a clear substance abuse problem. Well, he's not giving the answer people wanted.

Tiger cares a lot about his privacy, at least according to People. The mag cites an anonymous source who claims he won't hire a private driver because he "doesn't want anyone to watch over him or know what he is doing." The source adds that the legendary golfer also thinks he's fine to drive.

The insider goes on to say that Tiger "despises public scrutiny." It's pretty ironic, because he's come under plenty of scrutiny after getting busted twice for DUI.

As we reported ... Tiger was arrested on Friday in Jupiter, FL, after authorities say he was impaired while speeding on a two-lane road, clipped the back of a pickup truck hauling a trailer, and flipped his SUV.

According to the Martin County Sheriff's Department, Tiger went through a series of field sobriety tests at the scene, which he failed, and was then taken into custody.
