A child was injured in an early-morning crash between a tractor-trailer truck and car on Interstate 95 in Westport as snow started falling across the region.

The accident on the snow-slick highway took place about 4:45 a.m. between southbound Exits 17 and 16, according to Westport firefighters, who were dispatched to the scene.

A 2003 Toyota Corolla, driven by a Pennsylvania woman traveling with a 5-year-old child, collided with the tractor-trailer, causing the youngster to suffer a head laceration. The child was treated at the scene and then transported to Norwalk Hospital for more treatment. The woman and the driver of the tractor trailer were unhurt.

The highway's center and right lanes were shut down by State Police during emergency operations. The accident scene was cleared about 5:30 a.m.
