The 30 mph flashing sign is glearly uncalibrated. Passing it at 20 mph still indicates exceeding 30mph and brings All such signs into disrepute. The sign at the end of Gt Ashby Walk proves the car speedo is accurate. These signs are far more effective than cameras, but NEED TO BE ACCURATE!

Innacurate 30 mph flashing sign in Grace Way just past Vardon Road. The sign needs calibrating to check true speed. This current sign brings all such signs into disrepute lending itself to motorists just ignoring them, when they are more effective than cameras.
