In terms of what the Police would consider a speeding issue, they would look at any roads where average speeds are above the enforcement limit, which in this case would be 35mph. This is not the case here and the 85th percentile speeds (the speeds at which 85% of drivers are travelling at or below) are also at or below the enforcement limit at each of the four sites.
