Lindsay Lohan may have done it again ... dodged a jail bullet by the luck of the judicial draw.

We broke the story ... Lindsay will be arraigned today on 3 criminal charges -- including lying to cops -- in connection with her car accident on Pacific Coast Highway last June. We know the judge who will arraign her -- Commissioner Jane Godfrey -- will formally revoke her probation during the hearing. As you know, she's on probation for the jewelry heist case.

The Commissioner will order a formal hearing, and if the evidence shows it's more likely than not that LiLo committed a crime, the Commish could send her to jail for as long as 245 days.

Now the good news for Lindsay. One source very familiar with the Commish tells TMZ ... "Godfrey is not a big jail person."

Get this ... Commissioner Godfrey presides over Drug Court, in which she hears case after case involving people with serious drug cases. Godfrey strongly favors counseling over jail, to the point she has a graduation ceremony for people who complete the program and digs into her own pocket to buy little gifts for the graduates ... like Starbucks cards.

And the Commish presides over Homeless Court ... where she deals with homeless people who have committed crimes and gets them help to rehabilitate them, instead of throwing them in jail.
