Of course, reason number one is that a low BG could cause an accident. But some people think that won't happen to them, and today I became well aware of the less important reason for checking BG before driving. Today I got in an accident (the other driver was speeding and it was a bad junction). Both cars were written off but nobody was hurt badly (I have a bit of a bruised face and was knocked out temporarily, but nothing serious). Anyway, it was clear from the way the skid marks were on the road and the way the cars ended up that the other driver had been speeding, but right after the accident when I was in shock etc, I was so glad that I had checked my BG right before driving. Because I have no memory of the time before the accident, it was really reassuring to KNOW that my BG had been in range. I know of people who don't check their BG before driving and claim that because they can feel a low, they know that they are safe. I don't believe that is true, but even if it were, perhaps those people could be encouraged to test BG by being made aware of the fact that if they do not, they could be blamed for an accident which was not their fault.
