when on my bike or in the car reads 30mph these sign's say 28mph.
As far as I've experienced, the ones that actually give a speed seem to be pretty accurate based on what my Sat Nav says.
However the ones that just flash if you're over the limit often seem to be set deliberately low, eg there's one on the A32 which has flashed to warn me that I am "over" the 30mph limt when my speedo has been showing 30mph and Sat Nav has been reading about 28mph...
