Shannon Colburn, 22, of 139 Old Barn Road, Fairfield, was charged July 3 at 10:41 p.m. with DUI after another driver reported to police her 1999 Honda CRV swerving and tailgating another vehicle.
The officer who made the stop observed a strong odor of alcohol and perfume, according to the police report.
Colburn claimed to have had only one glass of wine.
A breathalyzer measured her blood alcohol concentration (BAC) at 0.308 in the field, and 0.305 at the police station. The legal limit is 0.08.
Colburn also failed to provide a valid insurance card, and was charged with DUI and lack of the proper insurance.
She was released on a promise to appear at Norwalk Superior Court on July 14.
