Just to clarify - I didn’t say DVLA has to be informed (unless like Harbottle says you’ve had severe hypos etc) but that finger prick testing has to be done and my understanding is that testing before and every 2 hours is required - but the gov.uk website certainly doesn’t make it clear - it refers out to other documentation that refers out to yet more!That’s not in the DVLA rules, you don’t have to inform the dvla about diabetes unless you take insulin or have certain complications. Though of course you should carry kit so you can test if feeling low.
Also, as Spudz says they’re testing 4 times a day to learn how food affects them, then it doesn’t sound like they’re testing around driving anyway.
Hopefully Spudz knows the requirements if he is driving :-D
