An Indiana State Police trooper and two Chicago men were injured early Wednesday when a driver lost control and struck them as they stood outside their vehicles on an icy interstate ramp.

Trooper Nicole Maenza, 24, and brothers Jorge Carrillo-Padilla, 41, and Ernesto Carrillo-Padilla, 37, were struck about 4:40 a.m. on the ramp from southbound Cline Avenue to eastbound Interstate 80/94, police said. Maenza and Ernesto Carrillo-Padilla were admitted to a hospital for non-life-threatening injuries.

Maenza was investigating a crash when she saw a Ford Expedition crash further down the sound barrier wall and went to check on the occupants, later identified as the Carrillo-Padillas, police said.

The brothers exited the Expedition and Maenza was telling them to get back in when a 27-year-old Griffith woman driving a 2015 Hyundai Sonata lost control and hit all three of them.

The woman told police she braked and swerved to the right to avoid hitting a car slowing ahead of her. She then lost control and hit a light pole. 

The woman heard people yelling and realized she's struck the trooper and two brothers.

Several other crashes along the Borman Expressway tied up traffic for much of the morning commute. The Indiana Department of Transportation's Northwest District said it had dozens of trucks on the roads after up to an inch of new snow fell overnight in some areas.

Commuters could see some relief the rest of the week, according to the National Weather Service. No additional precipitation is in the forecast.

Breezy northwest winds could cause wind chill values in the 20s Wednesday. Wind chills could fall into the single digits Wednesday night into Thursday, and temperatures could remain cool through the rest of the week.
