What Should The BAC Limit Be?

It is long past time to revisit the issue of BAC limits for driving once again, specifically for small amounts of alcohol, as it is already obvious for larger amounts.

Twenty-One Debunked believes that, in a perfect world, no one would ever dare to get behind the wheel after having even the slightest amount of alcohol in their system, period.  We would also have safe self-driving cars and state-of-the art public transportation, streets would be designed to maximize safety for all users rather than the convenience of only some users, and so on.  But unfortunately, we don't live in a perfect world.  And we never will either.  Think protopian, not utopian.

Thus, we need to be realistic in terms of what sort of BAC limits and penalties we set. Note that the swiftness and certainty of punishment is far more effective than severity.  And we need to prioritize getting actual drunk drivers off the road above all.  Focus on the sharks, not the guppies or dolphins. 

Borrowing from Denmark, one of the heaviest drinking cultures in the world and not even remotely a temperance society, we currently believe that the per se legal limit should be 0.05% in general, and 0.00% if observed to be driving recklessly.

Borrowing from most of Canada, we believe that only a BAC above 0.08% should carry  criminal charges, and 0.05% to 0.08% should be only a traffic violation with a brief administrative license suspension and brief vehicle impoundment and a modest fine.  For novice drivers of any age with less than two consecutive, accident and violation-free years of licensed driving, or under 21, whichever is longer, the BAC limit should be either 0.00% or 0.02%, also a traffic violation less than or equal to that above 0.05%.

If the limit is officially set to 0.00% for effect, any test result below the limit of quantitative (LOQ) must be treated as a presumptive zero (by that, I mean a conclusive presumption).  If it is a handheld breathalyzer device, or if the LOQ is unknown for the instrument, any result below 0.02% shall be a presumptive zero.  And all failing breathalyzer results should be confirmed on a second device.

Penalties should be graduated.  For those with above 0.08% but below 0.15%, a first offense should be a misdemeanor, in addition to any administrative license revocation.  There can also be an option to proceed only administratively and thus summarily.  Repeat offenses above 0.08%, or any offenses above 0.15% (or "aggravated DUI"), and/or with any kids under 16 in the car and/or when a serious accident occurs, should be automatic felonies with stiff sentences and heavy fines that can only be downgraded upon successful completion of an alcohol treatment program, that is, the classic "felony hammer".  And license revocations after the second offense above 0.08% need to be (more or less) permanent.  No more people still driving after their second, third, fourth, or fifth (!) DUI, ever again.

And those who drunkenly kill or maim innocent people, well, they need to go away for a very, very long time.  No excuses.  Do the crime, do the time.

And enforcement of these BAC limits should be done not only with checkpoints, but also with roving patrols as well, including the back roads especially.  And also use the "fish in a barrel method" in the parking lots of bars and clubs too.  We need to get these ticking time bombs off the road, yesterday.

So what are we waiting for?
