A stolen result can only ever be green or red. If green then this means that the vehicle has not appeared in the Police National Computer.
If the result comes back as red then this means that the vehicle is currently confirmed as stolen. The result will detail the information provided to us from the Police National Computer, including the constabulary which notified it of the theft.
Never buy a vehicle on this register as you stand to lose it, together with the money you paid for it.
