To minimize transmission of COVID-19, in spring 2020, most U.S. states passed policies promoting social distancing through stay-at-home orders prohibiting non-essential travel. Vehicle-miles traveled in the U.S. decreased by 41% in April 2020 compared to 2019. A new study led by researchers at the Center for Injury Research and Policy at Nationwide Children’s Hospital estimated associations between COVID-19-related social-distancing policies, traffic volume, and motor vehicle crash-related outcomes in Ohio.
