    Utah's .05 Legal Blood Alcohol Limit is Saving Lives

    2026/10/14 | 15 mins.
    About this episode:  
    In 2018, the state of Utah became the first state in the country to lower its blood alcohol concentration (BAC) limit for driving from 0.08 to 0.05. Within a year of implementation, the state's fatal crash rate dropped by nearly 20%. So, why haven't other states followed suit? In this episode: Dr. Federico Vaca, an expert in health and transportation, takes a close look at Utah's law, why it's been so effective, and how it can serve as a national model for safer driving.
    Guest: 
    Dr. Federico Vaca, MPH, is a physician and a professor of emergency medicine at the UC Irvine School of Medicine.
    Host: 
    Stephanie Desmon, MA, is a former journalist, author, and the director of public relations and communications for the Johns Hopkins Center for Communication Programs.

    Tom Burke, PhD, MPH, is an emeritus professor at Johns Hopkins and a former top official with the Environmental Protection Agency in the Obama administration.
    Host: 
    Dr. Josh Sharfstein is distinguished professor of the practice in Health Policy and Management, a pediatrician, and former secretary of Maryland's Health Department.
