A woman and a baby were hurt in a crash on Route 6 just west of Old Smethport Road in Mount Jewett.
Police say 24-year-old Jade Jensen of Mount Jewett was traveling west when a black Cadillac SUV going the opposite direction passed another car on a curve in a no passing zone, causing Jensen to swerve to avoid a collision and then hit a guard rail.
The Cadillac, driven by a woman with blonde, shoulder length hair, kept going.
Jensen and the infant were taken by Mount Jewett Ambulance to UPMC Kane for treatment of minor injuries.
Anyone with pertinent information about the Cadillac and its driver is asked to contact state police.
