You shouldn't drive if you've been drinking, but if you do, you need to be extra careful and you can't look suspicious and you definitely need to avoid the police. You shouldn't drive into the back of a squad car at 3am, for example. Amanda Bynes apparently didn't know any of this.
The LA Times says:
Amanda Bynes was arrested early Friday morning on suspicion of DUI in West Hollywood after she allegedly hit the rear corner of a sheriff's cruiser while trying to pass it. (She) was in custody at the West Hollywood Sheriff's Station before being released around 10:30 a.m. on $5,000 bail.
On the plus side, she was wearing a really short skirt and looked kinda hot when she left jail this morning. 3 years of probation is a small price to pay for sexy paparazzi pictures.
