A new study examining permanent daylight saving time reveals that such a policy would result in over 2 billion additional school commutes occurring in darkness for American children. The research demonstrates that fatal crashes involving school-aged pedestrians are approximately twice as likely to occur during dark morning hours compared to after sunrise. The findings suggest permanent daylight saving time poses significant safety risks and may negatively affect children's circadian rhythms.


This research provides critical evidence for policymakers debating permanent daylight saving time legislation, highlighting previously underestimated safety consequences for children. The findings indicate that scheduling decisions affect not only convenience but also child safety and biological health, with potentially preventable pedestrian fatalities at stake.
