I'd suggest that you would make a "reckless" mother. There is not a snowball's chance in hell that I would allow my teenage children to get in a car with anyone with a .05 BAC. I might not be able to prevent it, but if I knew, then they would not be going in that car.
'Now would you be willing to let your teenagers drive on the road if you knew everyone on the road (except your children) had a BAC of .08?
Indeed would you go out on the road yourself? I sure as heck wouldn't. Driving is dangerous enough when everyone on the road is sober.
I wouldn't let my teenagers drive, period. That's one of the reasons why I have no kids--because I know I would suck at it.
