Dina, 51, pleaded in a court in Long Island, New York to the charges made against her last September and was ordered to perform 100 hours of community service, reported TMZ online.
Along with her community service, Dina must attend a mandatory drinking and driving program, a victim impact panel, and pay the necessary fines and fees.
She is also expected to have her licence revoked and an interlock device will be installed in her car.
The 'Lindsay' star was initially arrested for driving at 'a speed of 77 mph in a 55mph zone' and police then discovered her blood alcohol level was twice the legal limit.
It was previously reported that Lindsay, 27, predicted her mother would be arrested for DWI.
