Basri Guzeloglu, the local governor, said the train slammed into the vehicle at a level crossing near the Mediterranean port city of Mersin.
All the dead were in the vehicle. Three of the injured were said to be in a serious condition.
Guzeloglu said the cause of the accident would be investigated, but media reports suggested a signaling fault that saw the crossing’s barrier arms up at the time of the accident.
No one aboard the train, traveling from the southern city of Adana to Mersin, was hurt.
Dogan news agency video footage of the scene showed the mangled wreckage of the vehicle lying near the tracks.
