90 quids in fines in two days

The context was a response to an FOIA request for the number of vehicles fined / charged for contravening ASL regs.

Ah, thanks, fudge. For some reason I didn't work out that it was talking abut stats. And it was also confusing that the second sentence didn't follow from the first, and the third sentence could have done with a 'therefore':

The advanced stop line merely creates a different stop line for different classes of vehicle. Accordingly there is no specific offence of contravening an advanced stop line. Our systems do not differentiate between automatic traffic signal offences at conventional stop lines and those at advanced stop lines.

My guess is that the police only record the offence at the level of the failure to comply with a traffic sign, and not what that traffic sign (or road marking, in this context) actually is.

Yes, in fairness to the police it has to be said that they do record a lot of information (e.g. the form for reporting a bike as stolen is very large and very impressive--and then people come along and the only thing they remember about their bike is that it was red). Still, it should be possible to track offences by different classes of road user at least and make reasonably accurate guesses as to what it was.
