Lindsay Lohan -- I'm Suing the Guy Who Said I Was Drunk

EXCLUSIVE

Linsday Lohan may be a really bad driver, but she was not a really bad drunk driver this week ... so she's going to sue the guy who accused her of DWB -- Driving While Blotto.

You'll recall.... Jose Rodriguez claims Lindsay struck him while she was driving a Porsche this week in NYC. Rodriguez gave an interview to a reporter and claimed Lindsay was slurring and "smelled like alcohol real bad" at the time of the incident.

The cops and others say Lindsay had not been drinking and alcohol was not a factor in the alleged incident.

We're told Lindsay believes she could lose work if people think she's off the wagon, so she's planning on suing Rodriguez for defamation.

Lindsay is saying, "I'm tired of people lying just to score a quick paycheck."
