Police say two women from Stamford were badly injured Monday after a tractor-trailer hit their car on the exit 3 ramp to I-95 in Greenwich.

Police say the tractor-trailer was trying to cross the intersection to get onto the entrance ramp to get back on I-95 south when it hit a Maserati driving on Arch Street Saturday morning.

The women in the Maserati have been identified as 38-year-old Christina Vomoca and 32-year-old Maiko Kobayashi.

Authorities say the two women were trapped, and the fire department had to get them out. Both victims are in critical condition at Stamford Hospital.

"The truck, it has a gross weight rating of 80,000 pounds, so it doesn't have to be moving very fast to create a lot of force. And, it T-boned the other car so it was a side impact. So, it was pretty significant wreck," said John Slusarz, of the Greenwich police.

Officials say that it doesn't appear as if the car or the tractor-trailer were speeding, but they are looking into other possible factors.
