You were doing 22.5% over the limit. That’s not even remotely close to minor. And with most speedos over reading you were probably doing an indicated 53mph maybe?
The policeman who pulled me over told me I was doing 49.
And according to NPCC guidelines it is ‘minor’, and eligible for a speed awareness course.
I’m just a bit miffed that they’ve added an extra £100 on when I’ve complied with their requests.
