The incident happened when a state trooper noticed a sport utility vehicle drifting between lanes and driving at unusual speeds, sometimes speeding up then slowing down to well below the speed limit on Interstate 90, near Bellevue Way, about 1:20 a.m. Friday.
When the trooper stopped the vehicle, he noticed the 19-year-old driver and a 20-year-old female passenger were naked, according to a state patrol news release. The woman began hiding alcohol containers and put on a shirt but the driver, from Seattle, made no efforts to cover up.
"There were some acts of physical intimacy going on in the vehicle that were best saved for not driving down the freeway," [State Trooper Jeff] Merrill said.
"We don't see it very often," Merrill said of nude driving.
"We harp on the fact that being impaired is so dangerous, but being distracted is equally as dangerous. I can't think of anything more distracting than this."
