Scottish Fire and Rescue Service crews attended the incident on the northbound carriageway between J11 Happendon and J10 Lesmahagow.
Appliances were mobilised from Lesmahagow, Larkhall and Douglas and firefighters arrived around six minutes later to find the large goods vehicle well-alight on the hard shoulder.
A fourth appliance from Lanark and the environmental protection unit from Hamilton were also called out.
There were no reports of injuries although the blaze produced large amounts of smoke and the motorway was closed in both directions. There were no homes in the vicinity.
