I can vouch for what Mike is saying, I got banned for 7 days for doing 102 on the M1, when the judge read the sentence it was Disqualified from Driving for 7 Days, 6 points and a £200 fine £20 costs.
I paid and went on my way, when my licence came back it just had the ban on it, no points.
If you are just over the 30mph over the prescribed limit like I was and Clare was, if you have a letter from your employer saying you would loose your job etc etc then you can get let off with just points and a higher fine, but its at the courts decision.
