RICHMOND, Va. (AP) - Police say seven people died in traffic crashes across Virginia over Memorial Day weekend.

Virginia State Police say four of the seven people killed over the four-day period were motorcyclists. Police say two of the motorcyclists killed were not wearing helmets.

Police say there were a total of six crashes, including a head-on collision in Rockingham County that killed two drivers. Police say neither driver was wearing a seat belt.

The number of traffic deaths over the four-day period is down slightly from last year when eight people were killed.
