FARGO - A teenage nanny looking after four children crashed and rolled on Interstate 94 here on Wednesday when another vehicle cut her off, the North Dakota Highway Patrol said.

Everyone was wearing seatbelts and the children were properly restrained, so there were no injuries, the state patrol said.

Sarah Swartz, 18, of Fargo, was taking the four children, ranging in age from 3 to 11 years old, from West Fargo to Fargo.

She was driving east on I-94 in a Chevrolet Tahoe when another car suddenly merged onto the interstate, cutting off Swartz, at about 3 p.m., the state patrol said. Swartz lost control of her Chevrolet, which rolled onto the driver's side, when she steered left to avoid colliding with the other car.

The driver of the other car was interviewed and the crash is under investigation, the state patrol said.
