There's an edge on the outside of the car that could injure someone — typically rust that's eaten through an arch and left a jagged lip, or accident damage that's left torn metal exposed.

Wording as it commonly appears on an MOT certificate: “Body has a sharp edge likely to cause injury”.

What does it mean?

There's an edge on the outside of the car that could injure someone — typically rust that's eaten through an arch and left a jagged lip, or accident damage that's left torn metal exposed.

How serious is it?

Usually recorded as: Major, Dangerous. The tester assesses the actual vehicle on the day, so your certificate is what counts.

What normally causes it?

  • Corrosion breaking through a wheel arch or sill
  • Accident damage never fully repaired
  • A trim panel or arch liner detached and leaving fixings exposed

What a mechanic would check

Walk round and run a hand near — not on — the suspect area. Then work out whether it's a trim item that can be refitted or whether the rust has gone right through the panel, because those are very different repairs.

What might need replacing

  • Trim or panel refitted or replaced
  • Welding and repair where corrosion has holed a panel
  • The edge dressed and treated where the panel is otherwise sound

Can you still drive it?

Can be recorded as Dangerous where the edge presents a real risk to pedestrians. It's usually straightforward to make safe, so there's no reason to leave it.
