Like I've said either way you have to declare either points with a code or a speed awareness course for the next 3 to 5 years depending on your insurance company.
Is there anyone on here who has recently renewed and has attended a recent speed awareness course? If so how much did it effect you? And what questions did they ask?
If you get points you'll tell them you have a SP50 which indicates it was on a motorway whereas the speed awareness course could be for anywhere and unless they ask where it happened, the speed of the road and what speed you were doing they can make assumptions that you were doing 85mph or 40 in a 30 and penalise you more.
Long gone are the days when the speed awareness course didn't need to be declared. Either way you loose but by how much is anyone's guess.
