I had always thought that the 10% ‘rule of thumb’ was to do with the practical (in) accuracy of car speedos not some way of letting blatant law breakers off the hook. It rather looks to me that this is a simple excuse to reduce Police workload. I would have thought that educate should start at the speed limit, if the car speedo was inaccurate then the driver would at least be aware of it then. Once the car is over the limit by 10% then FPs/summons should be issued and the car taken off the road until the speedo is fixed - oh and if the car has a sat nav there is no excuse at all on this count so just issue the FP at 1mph over. Just why is it that we seem to have this obsession with Educating when everyone is meant to have taken a statutory test, it just cannot be that difficult to understand surely?
The situation is slightly more complex.
This not an allowance or increase in the speed limit.
But it does show why the "trivial amount" claims are laughable
It was accepted that there is an accuracy problem with speedometers, so therefore a full prosecution could easily be challenged on these grounds. The reply was to make the 10+2 allowance for prosecution in a court. The 10% was (at the time) the required accuracy for a speedometer.
The FPN is considered appropriate below the 10+2, but above the speed limit.
So there are already concessions to offenders breaking the speed by a "trivial amount", it is just that some want even more leeway to break the law without any penalty
It is even more ironic that most speedometers overhead as manufacturers do not want to be placed n a situation where a driver sues because the speeding was due to an error in the manufacturer.
It is quite possible that if someone is prosecuted that the "trivial amount is in fact a choice to drive at 20% over the speed limit figure on their speedometer.
