NTSB Recommends Lower Drunk Driving Threshold Nationwide: 0.05 BAC

Officials for the U.S. National Transportation Safety Board have recommended a nationwide lowering of the blood-alcohol level considered safe for operating a car. The threshold is currently 0.08% — the NTSB wants to cut that to 0.05%. "That's about one drink for a woman weighing less than 120 lbs., two for a 160 lb. man. More than 100 countries have adopted the .05 alcohol content standard or lower, according to a report by the board's staff. In Europe, the share of traffic deaths attributable to drunken driving was reduced by more than half within 10 years after the standard was dropped, the report said. NTSB officials said it wasn't their intention to prevent drivers from having a glass of wine with dinner, but they acknowledged that under a threshold as low as .05 the safest thing for people who have only one or two drinks is not to drive at all. ... Alcohol concentration levels as low as .01 have been associated with driving-related performance impairment, and levels as low as .05 have been associated with significantly increased risk of fatal crashes, the board said."

    The world certainly would be entirely safe from driving accidents if nobody was ever allowed to drive. 0% is physically impossible: alcohols are a broad class of naturally occurring organic chemicals, that will be present at some (tiny) level in any human body, even if you have never taken a drink in your life. If you want to permit anyone to drive, then you'll need to set a non-zero limit somewhere; preferably above natural fluctuations in baseline level and measurement error. So, where to set the level? Do you need to check whether the driver has consumed a drink in the last year? Week? Hour? Minute? Rather than setting a useless/impossible "0 is lowest, so it must be best" limit, one should look at *actually available data* to determine how alcohol levels correlate with actual increases in accidents.

    There is significant literature from EU authorities (and each of the member states local DOT).

    Bottom line is:
    * 0.08 is the last "safe" limit. Performance is already decreased, but It is approximately equivalent to driving with children in the backseat. Not the best, but acceptable risk. About twice as bad as 0.05.
    * However, above 0.08, performance decrease sternly and exponentially. At 0.1, chances of death or dismemberment become alarmingly hight. It is not obvious for a driver to make the distinction between 0.08 "happy" and 0.1 "drunk", since one may not feel impaired, but he is, really.
    * Anything over 0.12 is classical "drunk driving" as understood by common folks. Chances of accidents are extremely elevated.
    * 0.05 is the bottom of the exponential curve. There are still benefits from driving with a lower BAC, but the lions share of the exponential decrease is passed. The difference with 0.08 is significant (half less chances of accident, or more, more pronounced for young drivers). Below that, chances of accident continue to decrease, but not as quickly, so there is little benefits to be reaped going even lower.

    Another interesting point is that effect of BAC on drivers is very age related. Being drunk at 0.1 when you are an experienced driver in your 30's puts you back at the same risk as when you were 16 and road racing everywhere and everyone (this is bad, indeed). However, a teen driver at 0.08 is already at extreme risk (as if he was an experienced driver at 1.4 or more from my memory), the statistics I read just showed this result, but didn't explained why. Could be that most 30+ have acquired some sort of higher alcohol resistance, or that it requires more focus from teen drivers, focus that cannot be achieved when intoxicated, even mildly. Anyway, teens that consume alcohol should never drive, even at legal concentrations.

    One can already be arrested for having less than a .08% BAC in Georgia, and many other states. I'm not sure about the statue on other states, but in Georgia, according to the O.C.G.A.(Official Code of Georgia Annotated), one is considered "less safe" if law enforcement can provide proof that the driver was "under the influence" at a level below the "legal limit". I have arrested many people under this portion of the DUI statue, in Georgia.

    Usually, I would establish "less safe" with video and audio recordings of the driver's inability to maintain lane and other moving violations, as well as my encounter with the driver, and the sobriety tests administered during the stop of the particular individual. "Less safe" is important, as it removes bureaucratic roadblocks from stop those that aren't capable of possessing a certain amount of alcohol in their bloodstream and operating a motor vehicle. The NTSB is doing nothing that isn't already enforced in many, possible most or all states currently.

    There are people that can safely drive with 0.08% BAC, and higher. While I personally don't consume alcohol, I do consume narcotics for severe pain relief. If one took my blood and observed the levels, they would probably wish to jail me on those numbers alone. The issue is that it's safe to allow me to operate a motor vehicle, as I'm not "under the influence"(I don't experience the negative effects of narcotics, and even have a high tolerance against some of the positive effects), or my state of alertness and readiness isn't impacted in the slightest. That is what the people should be concerned with, whether the driver is "under the influence", "less safe", or simply whether the individual isn't capable of safely operating a motor vehicle.

    Eventually your luck will run out, even if not necessarily because of being caught (we'll get back to that), but because you'll cause an accident. When the road situation is relaxed, you are safe. As soon as things get tight or there's something unexpected, your performance is impaired, and it's simple objective measures such as reaction times and visual acuity we're talking about.

    Now, nystagmus leads to loss of visual acuity at higher spatial frequencies while, perhaps counterintuitively, boosting the contrast at lower spatial frequencies.

    This means that if you get motion-induced nystagmus, as you're likely to at 0.08% BAC and up, you won't be able to read the fucking speedometer or even roadside signs, and your brain will be substituting expected values for actual ones. That's how some drunk drivers are getting caught, and they swear they were not speeding. That's how some military and aerobatic pilots end up with doing controlled flights into terrain in instrument conditions - they don't see the artificial horizon without realizing it.
