Photos show a wrecked van in the aftermath of a crash involving a Royal Mail vehicle in Gorleston.
The three-vehicle crash happened in Beccles Road, Gorleston, just before 10am on Monday.
Police and ambulances attended the scene, and an adult man was taken to the James Paget Hospital for further assessment and treatment.

An eyewitness said: "It's very badly damaged on the front end.
"The side airbags in the Royal Mail van had gone off.
"I think an accident investigation may be required. The white van passenger door was open like someone had to be extricated.
"Only the white van driver was at the scene with the police, so I presume the Royal Mail driver was at the hospital, or a passenger from the white van if there was one."

A full road closure was in place in Beccles Road at the time.
No pictures have surfaced of the third vehicle that was involved in the collision.
It remains unclear if it was recovered before the two vans.
