A Chronobiological Evaluation of the Acute Effects of Daylight Saving Time on Traffic Accident Risk (Current Biology)

Reports about Daylight Saving Time (DST) and traffic accident risk are inconsistent. Fritz et al. show that the spring DST transition acutely increases fatal accidents, especially in the morning and locations further west in a given time zone. Results do not support claims that DST reduces afternoon rush-hour accidents due to better illumination.
