Can having less than one drink impair your driving?
I was the designated driver last weekend for an outing with some friends. Halfway through the night, one of my friends bought a round of cocktails and the bartender accidentally made one extra. I didn’t want it to go to waste, so I had some. Another friend got annoyed at me for drinking when I’m supposed to be driving, but I didn’t finish it. Am I safe to drive if I’ve had less than one or two drinks?
