It must be the years I spent with logic diagrams and programs combined with a reasonable stable of bikes that keeps me finding holes in the SORN system
Here is another
Small trail bike 6 weeks tax left insurance runs out so I SORN it (otherwise I have committed a heinous crime and will be fined the legendry fine of 1K) minisule tax cant be reclaimed not a problem. 15 days before tax runs out get the nag letter to tax or SORN (clearly missing logic IF ALREADY SORNED THEN DONT SEND) anyway just checking that I am sorned (not that I dont trust the rickety system
I enter the 16 digit sorn reminder number .the system says I have entered the wrong number check 16 digits (always fun) and again 'wrong number', it damm well is not, its another "already sorned" check missing. But to allay my fears I get out the V5 enter reg number and V5 check number bingo already SORNED. they could not program a pop up toaster but they sure can levy fines
