DVLA says if blood sugar is below 5, then you need to have a snack before driving.
If it was me and I was 4.6, i would have something to eat and re-check to see that I was above 5 before driving.
Does this mean that she would have been ok to drive as she was 4.6 then had her breakfast?
On the paperwork they send you it doesn't mention driving whilst high at all.
Yeah I hate that 45 minutes thing, especially if I was only 3.8 or similar. I was late for work a couple of weeks ago because I got int he car and tested and was hypo so couldn't drive. Happened twice recently actually.
if you were 3.8 and you ate some sugar you should have felt better within about 10 mins, i would have got in the car and let the sugar increase my levels while i drove.
