Study finds fatal car crashes spike the week after the clock springs forward for daylight saving time

Fatal car crashes in the U.S. spike by 6% during the workweek following the daylight saving time change, resulting in about 28 additional deaths every year, according to a study.

The risk increases the farther west a person lives in a time zone and is worse in the morning, said the study by researchers at the University of Colorado Boulder, which analyzed more than 700,000 fatal crashes reported from 1996 to 2017 .
