COLUMBIA — State Rep. Ted Vick has been arrested on the Statehouse grounds and charged with driving under the influence, his second such charge in less than a year, but his lawyer said his client was not impaired.

Vick, D-Chesterfield, was arrested at around 11 p.m. Tuesday by the Bureau of Protective Services, according to the Department of Public Safety spokeswoman.

An officer saw Vick stumbling as he walked into a parking garage on the Statehouse grounds. Vick got into his truck and hit a cone before the officer could catch up and ask him to stop.

Vick smelled like alcohol and refused field-sobriety tests, according to an incident report. The officer called for backup, and Vick was eventually taken to the Richland County jail, authorities said.

Vick’s lawyer, fellow Rep. Todd Rutherford, said Vick was not impaired. Vick was walking funny because he had a rock in his shoe, said Rutherford, D-Columbia.

“The way he walks does not dictate the way you drive. And (the officer) only saw him driving 20 feet,” Rutherford said.

There is no audio or video of the arrest, and Vick drives a large pickup truck that can be difficult to maneuver in some of the tight spaces in the Statehouse garage, Rutherford said.

Vick was released from jail after several hours.
