Brendan Begnal, 31, of 111 Compo Road South, charged Saturday with drunk driving.

Police said an off-duty officer observed Begnal traveling erratically on Greens Farms Road about 2:30 p.m. Following the car, it ended up hitting a stonewall at 25 Compo Road South, police said.

After an on-duty officer arrived, the officer reportedly smelled alcohol on Begnal's breath. Begnal failed field sobriety tests, police said.

Begnal was charged with operating under the influence of drugs or alcohol, failure to drive in the proper lane, having insurance coverage that failed to meet minimum requirements and failure to renew registration.

He was released on $500 bond, and is scheduled to appear July 26 in Norwalk Superior Court.
