Should legal blood-alcohol content level be lowered in name of safety?

• Mar 3, 2019 at 8:00 AM

 In the United States, motor vehicle accidents are a leading cause of injury and death. With 29 Americans losing their lives to alcohol-related driving incidents daily, alcohol consumption is the single greatest contributing factor.

A heated public debate has resulted surrounding the legal blood-alcohol concentration (BAC) level and new legislation has been proposed to lower the legal limit.

In a new paper published in the American Journal of Public Health, Dr. Stephanie Morain, assistant professor in the Center for Medical Ethics and Health Policy at Baylor College of Medicine, examined the issue and makes an argument for amended legislation in favor of public health and safety.

“We authored this paper in response to a recent report from the National Academies of Sciences, Engineering and Medicine that proposed potential strategies to reduce alcohol-impaired driving deaths, one of which is to lower the legal BAC level,” he said.

“While this is a controversial approach, this paper gives us an opportunity to examine the ethical acceptability of lowering the legal BAC level from .08 to .05.”

Following the special report from NASEM, at least four states, including Hawaii, New York, Washington and Delaware, proposed legislation to lower the legal BAC level to .05, with the law officially passing and going into effect in Utah in 2018.

Even though this proposed legislation could effectively reduce alcohol-related injury and death, many critics claim such a law restricts individual freedom and criminalizes responsible social drinking.

“We make the distinction in our arguments that this law would not penalize or prohibit social drinking, but rather penalize alcohol-impaired driving. A person can still drink as much as they like, just not get behind the wheel. Our society has made it increasingly easy to find a safe ride home through ride-share applications and other resources,” Morain said.

Overall, the purpose of the recommendations is to protect the health of the population, as is true for public health in general. The BAC .05 law in particular would benefit two central population groups; the drinking driver and the parties negatively impacted by drinking drivers, including pedestrians and other passengers, as well as the families of victims.

“In the public health ethics field, it is acceptable to restrict individual freedom in order to prevent harm to others, and the BAC .05 laws are a shining example of this philosophy,” Morain said.

“With Utah passing legislation to reduce the legal BAC level, we hope this signals a window of opportunity for similar legislation to be adopted across the country.”
