(Home) Speedo legality

I've still have my speedo in Killometers is that illegal? - (#587) Gwyn Wilde, 18 Jul 01

Hello Gwyn,
I had this nagging doubt but was assured by an MOT garage that the speedo was legal as KM's were recorded on the certificate. However, because of the very critical difference between being "booked" by a camera and not being booked, I have attached a perspex "dial" to the speedo to give MPH equivalents. - (#596) John Davis, 19 Jul 01

I've been through 2 MOTs and also raised it with the testing garage. They say its ok with kph only. I've never bothered converting the dial, just remember the conversions for the important speeds like 30 and 40mph. The others I convert in my head, passes the time while waiting for the van to get up to speed (ok so I'm very slow at maths - joke).
