Lindsay Lohan -- The Cops Are Out to Get Me

Lindsay Lohan is telling friends ... cops are on such a vendetta to bring her down.

And get this ... Lindsay still claims she wasn't driving at the time her Porsche slammed into a truck last June on the Pacific Coast Highway. TMZ broke the story ... authorities beg to differ and will prosecute her for lying to cops. Lindsay claimed she was a passenger, but witnesses say she was behind the wheel.

Lindsay is saying she's "terrified" of going back to jail, especially because Judge Stephanie Sautner made it clear she would violate her probation if she breaks the law again.

Lindsay says she will throw herself at the mercy of the court ... she believes "One car accident could ruin everything for me."
