Is 0.05 Percent the new 0.08 Percent?
Since 2013, the National Transportation Safety Board (NTSB) has advocated that the legal blood alcohol level (BAC) limit for drivers in the United States be lowered to 0.05 percent or even lower. Citing numerous studies in other countries where the legal limit is 0.05% or less, the NTSB makes the case that even at 0.05% BAC, which for most people is the equivalent of one or two alcoholic drinks within a period of an hour or so, the risk of a driver being in a vehicle crash is at least twice as likely than for a driver with no alcohol in his or her blood. One such study noted by the NTSB is a finding that in Australia, there was an 18 percent decrease in fatal vehicle crashes when the legal BAC was lowered from 0.08 percent to 0.05 percent. Indeed, almost all countries have a BAC threshold that is less than the 0.08 percent that currently applies in all fifty US states.
But states are free to set their own BAC thresholds and the NTSB recommendations are starting to show an impact. In March of 2017, Utah became the first state to pass a law, which becomes effective in 2018, to lower the legal BAC limit to 0.05 percent. Two other state legislatures, Hawaii and Washington State, have or are considering similar legislation. The Hawaii bill was rejected but a Washington house bill to lower the BAC limit to 0.05% is currently in committee.
