One appliance and crew from Haddenham, one from Aylesbury and one from Thame attended, along with an officer.
An HGV lorry had fallen onto its side and was resting against the pole of an electricity cable.
One man had released himself from the vehicle.
The firefighters mopped up a small amount of diesel which had leaked from the lorry and made the scene safe.
The incident was left in the hands of Thames Valley Police.
