Emergency services responded to a two-car collision in Aylesbury yesterday.
Two appliances and crews from Aylesbury were sent to Cornbrook Road at just before 12:30pm on Thursday.
Two men were out of the cars on arrival.
The firefighters used hydraulic rescue equipment to release a woman who had become trapped, injured, passing her into the care of the South Central Ambulance Service.
They also used an environmental pack to help stem a fluid leak.
There was a road closure put in place, and the incident was left in the hands of Thames Valley Police.
