Speeding on the dual

The only time I was caught speeding I was doing 43mph in a 40 and was within 100 metres of the end of speed limit.  I was slightly miffed, this was by a policeman with a speed camera, he pointed out that he had to take it seriously as I was outside a school, I didn't mention to him that it was 6am on a Saturday morning in the school holidays.  That was in 1994 so guidelines might have been different then.

Indeed. AFAIK there were no national guidelines at the time.

The predecessor to the NPCC was the Association of Chief Police Officers (ACPO). They revised their guidelines in 2011 and as far as I can see the only change made then was to increase the tolerance where a course would be offered from (Limit+10%+6mph) to (Limit+10%+9mph). I cannot establish what guidelines existed before 2011, whether they made an allowance of 10%+2mph and if they did, when that was formally introduced. The NPCC adopted the ACPO guidelines in full when that organisation was formed to succeed the ACPO in 2015.

I've done a quick analysis on the Northamptonshire 2020 data and no speeding offences (as far as I can see) saw action below the 10%=2mph tolerance.

pepipoo would be very interested as they have seen evidence of this...

They would. However, not because they have seen evidence of it but precisely the opposite - they haven't. I've heard many reports of people seeing action for speeds below the NPCC's guidance threshold - especially in 30mph limits. I've never actually seen anybody post their NIP, though.

Yes, sorry a typo on my part, i missed out 'no'

This is interesting. Thank you for posting. Will try & find my local force, & see what they have recorded.

My Speedo read’s  75 mph and sat nav 72 mph.
At most speeds your car will show about 3 mph more than you are doing.
So you should be fine.

As long as the OP wasn't going faster than 78 before they saw the van.  The van often sees the speeder well before the speeder sees the van.

Single carriageway, national speed limit. 60 for cars, 50 for GVs.
