speed you will see how far out they are.

Now that is interesting, I drive a sprinter with digital tacho, the governor is controlled by the tacho not the speedo. Limit set to 56 mph when speedo is reading 60 mph and tested against sat nav the tacho is accurate. Mercedes offer a range of governed speeds on the sprinter but because of the weight mine was tachoed and limiter runs from that. It was all part of the versalift conversion of the new vehicle.

out in an old DAF last night and the speedo said 54 but sat nav said 57 as i could overtake Irish trucks the sat nav must have been right, 8-) wonder if anybody has had a speeding ticket because of this!

If they're on a motorway, the answer is no because the limit is 60.
If on a single or dual carriageway, then yes because 54 or 57 is speeding regardless.
