At about 5:30 p.m. Saturday, a southbound tractor-trailer that was exiting Interstate 95 at Exit 3 in Greenwich and was travelling across Arch Street to jump on to I-95's entrance ramp to continue southbound on I-95 when the collision occurred with the passenger vehicle that was traveling south on Arch Street.
Police have not identified the tractor trailer driver. The Greenwich Fire Department had to forcibly extract Vomoca and Kobayashi in order to allow GEMS personnel to treat them.
The car's occupants were trapped, and the fire department had to extricate the driver and passenger from the damaged car, police said. They were then transported to a local trauma center with life-threatening injuries. The driver of the truck was not injured, police said.
The accident on Exit 3 occurred about an hour after a fatal crash occurred along I-95, which was causing delays and traffic tie-ups in the area.
This collision remains under investigation, Greenwich Police said.
