A crash involving 11 vehicles on the M6 motorway in Lancashire was caused by fog, police have said.
Visibility was reduced to about 30ft in places on Sunday morning.
The crash involved seven cars and four lorries and happened close to junction 29, near Leyland, south of Preston, at about 01:40 GMT.
One person was trapped in a lorry and had to be released by firefighters. Six people were injured, none of them seriously.
The motorway was reopened in both directions just before 09:00 GMT.
Police said the person rescued from the lorry was taken to the Royal Preston Hospital for treatment while the other five people were treated at Wigan Infirmary.
