A LORRY overturned at JCB's demonstration site in Ashbourne's airfield, trapping the driver inside.
The tipper lorry, owned and run by a contractor working for the digger firm, was unloading soil when the incident happened.
Several crews were sent from Derbyshire Fire and Rescue Service because the call initially stated a lorry had trapped a car in the industrial estate.
The fire and rescue officers from Ashbourne cut out the lorry's sun roof to let a paramedic climb inside and stabilise the male driver, who was conscious but injured, and he was removed on a spinal board to be taken to hospital by ambulance.
An air ambulance attended the incident, which happened at around 1.10pm, but was not required.
