LOUISVILLE, Ky. (WDRB) -- Kentucky Senator Rand Paul's son has been cited for driving under the influence of alcohol.

Lexington police say 22-year old William Paul crashed his truck into the back of a parked car Sunday morning.

He was later cited for DUI and failure to maintain insurance.

William Paul was not arrested, which police say is standard for this type of case. 

Paul's photo comes from 2013 and an unrelated assault arrest in Charlotte, North Carolina.

That case was dismissed.

Rand Paul declined to comment.
