Caravan crash causes chaos on M1
Highways England partially closed off the northbound carriageway between J29 for Mansfield and Chesterfield and J29A for Markham Vale and Bolsover around 10.30am.
The collision, between a caravan, a Suzuki Swift and Ford Focus, caused a 20 litre oil spillage on the carriageway.
A police spokesman said there were no serious injuries.
Contractors have now cleaned-up and fully re-opened the carriageway.
The traffic is beginning to ease.
