It happened last Sunday evening.
We are appealing for witnesses after a road rage attack off the M55 in Greenhalgh.
Police were called around 6.55pm on Sunday (May 23) to a report a man had been attacked in Fleetwood Road, close to Junction 3 of the motorway.
A man reported he had been driving a blue Ford Focus eastbound when the driver of a grey Volkswagen Polo cut across his vehicle.
It was alleged the Polo driver continued to drive alongside and cut across the Ford, with both drivers leaving the motorway at Junction 3.
The Polo driver then stopped his vehicle, blocking in the victim’s vehicle, with a man getting out and punching the driver of the Ford.
The offender got back into the Polo before leaving the scene, with the victim needing hospital treatment.
Police are appealing for witnesses and urging anyone who saw the attack to come forward.
PC Tina Hinchliffe, of Lancashire Police, said: “This was a nasty and violent assault which has left the victim very shaken and upset.
“This is a busy junction and I believe a number of people would have seen what happened, particularly with the Ford being blocked in.
“Please contact us if you can help.”
Anyone with information can contact police on 101 or email email@example.com quoting log 1287 of May 23.
