Amanda Bynes — Legs It to the Impound Lot

Amanda Bynes just went to an L.A. tow yard to pick up the black BMW she allegedly crashed into a cop car this morning … wearing the exact same hoochie outfit she wore during the arrest. 

Bynes — who was clutching a bottle of water — was clearly suffering from a painful hangover … following her DUI in West Hollywood at 3AM.

As we previously reported, Bynes spent several hours in jail … before posting a $5,000 bail.

Now, she”s out … and back on the road.

You”ve been warned.
