ROYALTON — Four people were ejected in a motor vehicle crash on Interstate 89 in Royalton on Monday afternoon, according to a news release from Vermont State Police.

State police troopers responded to a call about a rollover crash near mile marker 19 north on I-89 at about 3:24 p.m. Monday.

They found four people, including a 4-year-old girl who was not buckled into a car seat, had been ejected from a 2002 Toyota Tundra driven by 31-year-old Matthew Hallock, of Montpelier.
