Dina Lohan just showed up in court in New York a few minutes ago and pleaded not guilty to drunk driving charges ... but she wasn't just allowed to go ... because the judge suspended her license.
Dina showed up with her attorney, Mark Heller -- the same guy Lindsay used -- who argued that Dina didn't have a criminal record ... and the judge released her without bail. Then they faced reporters outside the courthouse.
As we reported ... Dina was stopped for speeding on a Long Island highway earlier this month and cops say she blew a .20 on a breathalyzer. She was ticketed for DWI and speeding.
No license? No problem. Dina was driven away ... in a silver Rolls-Royce.
