Cllr Mirfin is concerned the speed indicator devices are not worth the money A councillor has raised concerns over the effectiveness of Speed Indicator Devices (SpIDs) on many of the county s dangerous roads . Ribble Valley Councillor, Ged Mirfin, said the number of SpIDs in Lancashire is higher than anywhere else in the country, but argues they are not cost effective, and claims speeding could be managed better if permanent measures were put in place. A SpID is a device that raises driver awareness by displaying the vehicle s speed or a smiley or sad face, depending whether the driver is above or below the speed limit.
