Had a look at my guidelines...if you are clocked doing 61 -80 mph in a 60 limit zone its a band A fine and 3 points.
Band A means that you are fined according to your income..
Dont know why you were not offered a fixed penalty but it could be that you are a new driver with 3 points already or you have 9 points making you a totter.
ACPO guidelines suggest a fixed penalty is appropriate up to 86mph in a 60mph limit.
New drivers with three points are not summonsed in the same way as other drivers with nine are, Maggie. There is no need as the six point revocation is undertaken by the DVLA, not the magistrates.
