Investigators in Livingston County say a woman was impaired by drugs during a crash in June that injured her passenger.
Sadie Wagner of Wayland is being charged with vehicular assault, driving while impaired and failure to yield.
Authorities say she drove into the path of a tractor trailer at the intersection of Route 36 and the I-390 off ramps in North Dansville.
A man riding with her suffered broken ribs and a broken sternum.
Authorities say tests have confirmed Wagner was under the influence of fentanyl.
