One appliance and crew from Newport Pagnell, one from Broughton, one from West Ashland, two from Mereway and an officer attended. No-one was trapped. About 100 litres of engine oil spilled on to the carriageway.
Firefighters helped separate the lorries in readiness for recovery services, and to carry out a thermal scan on the engine compartment of one of the lorries.
One of the lorries was carrying flour and the other one aluminium.
