[duck]

Here in Virginia in the late 90's, there were a string of incidents with Type 1 diabetics causing all manner of issues on the roads; the culmination of which was a trucker who would not pull over after being observed swerving all over the road. After a long chase, and lots of damage, his truck was disabled (I forget how, I think he ran into something) and it took a number of cops to subdue him (and of course, they beat the tar out of him because he was beligerent and resisted arrest--then later he sued for undue force)...

After all that, the Commonwealth of Virginia passed a number of laws that basically say if you are a diabetic and you cause an accident because you are low or otherwise out of control, you lose your license at least one year. Now, you can try and prove you were not low at the time, as VA knows meters keep records, etc. But my point is, it's not the once-volatile insulins that cause driving issues for the most part, its negligence on the driver's part (as many accidents are).

So, stay in control, test before you drive, if you feel weird pull over and test again. It really is that simple, but most of us resist such action. And yeah, it is unfair that the actions of a few reflect on all of us, but that's life I suppose.
