Lohan, 50, was surrounded by a media throng usually associated with her troubled actress daughter, Lindsay Lohan, as she left a Long Island courthouse following her arraignment. She was released without bail until her next court appearance on Oct. 23.
The only apparent family member accompanying Lohan to court was her mother, Ann Sullivan.
Judge Joy Watson released Lohan without bail but ordered her driver's license suspended, citing the severity of the alleged drunken driving charge.
State police arrested Lohan on Sept. 12 after stopping her for allegedly driving 77 mph in a 55 mph zone on a Long Island parkway. Police said her blood-alcohol level was 0.20, more than double the legal limit of 0.08.

"Dina Lohan is painfully mindful of the gravity of her arrest for driving while intoxicated," he said. "I am confident that the district attorney's office and the judicial system will temper justice with mercy."
Lohan's arrest about nine miles from her Merrick, N.Y., home came just months after her 27-year-old daughter completed her sixth stint in rehab for drug and alcohol abuse.
In an interview with Oprah Winfrey this summer, the younger Lohan admitted an addiction to alcohol which she described as a gateway to other drugs. The actress's father, Michael Lohan, also has said he has dealt with drug and alcohol addiction.
