Many years ago in my reckless youth I was taken to court for no tax or mot and it wasnt a criminal offence, it was classed as motoring.
Also in my motorcycling days I received a 21 day ban for speeding ( average of 107mph for 3 miles on the A14 ) and it was classed as motoring.
So unless they`ve changed the laws, which they may have, I wouldn`t worry too much.
If everybody that was caught speeding was given a criminal record i`m sure most of the UK would be criminals!
