Two people were struck by a suspected impaired driver Saturday after they parked their vehicle on the shoulder of Sunrise Highway in Southampton and got out to shoot a video, authorities said.

State Police said Ulyana Yaremko, 20, of Hampton Bays, was heading east at about 11:30 a.m. when she lost control of her 2007 Pontiac.

The car skidded sideways, hitting Crystal Hayes, 34, and Christopher King, 38, both of East Hampton, and their 1994 Jeep Grand Cherokee, police said.

Troopers arrested Yaremko for driving while ability impaired by drugs after she was treated and released from Southampton Hospital. She is scheduled to be arraigned Sunday morning in Southampton Town Court.

Hayes and King pulled over between Exits 64 and 65 to take a video of a small brush fire nearby, according to police.

Hayes was airlifted to Stony Brook University Hospital in serious but stable condition. King was taken to Peconic Bay Medical Center with non-life-threatening injuries, police said.
