This is the moment a 4x4 turned into a fireball on the outskirts of Colchester.
The vehicle burst into flames on the A120 hard shoulder just before the Colchester turn-off.
Witness Alan McKay-Firth, who snapped this photo, said: "I was worried the tank was going to explode and take three or four cars with it.
"I know it was diesel but it can still go off with a right bang - I've seen it happen before."
The drama happened at 5.15pm on Saturday.
