If you're copping for the points without going to court, it will be a standard £60, it's not a sliding scale unless a judge gets involved. Got caught doing 47 in a 30 (that used to be a 50, then a 40 - and a non-residential area), and it was 30 points SP30 and £60.
I don't know if the laws are different in England but the police told me they couldn't offer me a Fixed Penalty Notice of £60 & 3 points as it was a certain % over the limit. So it was up to the procurator fiscal to deal with.
The citation came in today (hand delivered) and I've to go to court in a couple of weeks!!
Seems a bit excessive if its just the standard £60 & 3 points!
I can speak as someone who was caught driving 'enthusiastically' on a clear, straight country road in good weather.
My speed was 3 mph above the limit it which they *could* offer a fixed penalty notice (3 points and a fine). So I got a summons. You do
not have to appear in person if you are pleading guilty. Something to note is that they *can* opt to take you to court for any speeding offence (even 1 mph above the limit) but they won't as it would clog up the courts.
If they intend to take your licence away, they will recall the case and let you know that you must attend.
Interestingly, a relation was done about 4 months later doing the same speed in a 60 zone and although a very different part of Scotland, they got the same points and fine. I guess that there is a table that they use to work it out.
My fine was £250 and I got 4 points. My relation got exactly the same. I was caught in Midlothian he was caught in the Highlands.
