WASHINGTON, May 4 Representative Patrick J. Kennedy crashed his car into a traffic barrier on Capitol Hill in the early morning hours on Thursday. He said he was apparently disoriented because he had been taking Ambien, the sleeping pill, and another medication.

Mr. Kennedy, a Rhode Island Democrat, said he drove to the Capitol at about 2:45 a.m. in the mistaken belief that he needed to vote. The House was not in session, having adjourned at 11:59 p.m. on Wednesday.
