Two people escaped from their burning car after it rolled into a field and hit electric cables in Cambridgeshire on Sunday morning.
Fire crews were called at 0245 GMT after reports of a vehicle on fire, possibly with occupants possibly inside, on the A47 Wisbech bypass.
Fire fighters arrived to find the two people in the car had escaped unhurt.
The electric cables are not believe to have interfered with the fire, but the power was isolated at nearby homes as a precaution.
It is not known how the car came to leave the road.
