After taking a crash course on DUI, I choose to never drinking a drop if I am going to drive. I probably had a 0.06 BAC or less when I got in the car, but my life was nearly ruined by the charges.Definitely. I'm planning on buying a 100 dollar unit to put into my glovebox. Not as a "Hey, I'm good to drive!", but as a reminder of "no, this is what your BAC actually is right now." kind of thing.
If you don't drink you'll know what your BAC is... 0.00
