Ten drivers face prosecution after blocking the emergency services from getting to a crash on the M6.
The motorway was closed for most of Friday after a lorry carrying beer collided with a camper van and a car and shed its load of bottles and crates over the northbound carriageway at about 14:00 BST.
Lancashire Police said vehicles that used the hard shoulder to exit at Junction 28 delayed the 999 response and those drivers will have to go to court.
Seven people were hurt, but their injuries were not thought to be life-threatening, the force said.
In an update on X, Lancashire Road Police said: “Following the collision on M6 between J27 and 28 Friday afternoon emergency vehicles were prevented from access to the scene due to drivers using hard shoulder to exit at J28.
“Notice of intended prosecutions have been posted to drivers of all ten of these vehicles.”
