A 10-CAR crash on the M6 saw a man suffer fractured ribs and a concussion while a teenager was left with whiplash.
The emergency services were called around 5.30pm on Wednesday after reports of a major incident close to Junction 28 near Leyland.
A 50-year-old man from Buckshaw Village suffered fractured ribs and a concussion, while several others were left with whiplash including a 15-year-old boy from Chorley.
