Sheriff's deputies say a car driven by 29-year-old Laura Johnson crossed the center line and hit an oncoming car, driven by 59-year-old Nancey Wilbur, on Route 21 in the Town of Hopewell around 4 p.m.

A third vehicle swerved to avoid the accident, but the impact of the crash pushed Wilbur's car into it.

The driver of that car, 54-year-old Christopher Howland, was treated and released at the scene.

Johnson, the driver of the first car, had a toddler and an infant in her car, and all three were taken to Strong Hospital and have since been discharged.

Wilbur, who was in the car that was hit head-on, was airlifted to Strong where she remains in guarded condition.

Deputies say the cause of the crash remains under investigation.
