Tami Erin -- the actress who played Pippi Longstocking -- was arrested Saturday afternoon for felony hit and run and drunk driving ... TMZ has learned.
Erin was driving in L.A. when she allegedly hit 3 cars and took off. Law enforcement sources say at least one person was taken to the hospital.
And get this ... Erin didn't hit them all at once -- we're told she hit the first car then drove off ... then hit another car and drove off ... and then she hit the last.
When cops found her they did a field sobriety test and then arrested her for both the felony hit and run and DUI. One source says she was "totally out of control ... just out of it."
Erin refused to submit a blood alcohol test ... and her bail was set at $100K.
As TMZ first reported ... Erin's latest screen credit is a gnarly sex tape.
1:23 PT -- Tami just bailed out of jail.
