This Is the Deadliest Day to Be on the Road Every Year, Data Shows

The most dangerous time to be behind the wheel is not when you would expect.

Every year, road accidents claim the lives of over 38,000 Americans, making it the leading cause of death for individuals between the ages of one and 54. An additional 4.4 million accident victims survive but are injured badly enough to seek medical attention, according to the Association for Safe International Road Travel.

And while staying vigilant while driving should be an everyday habit, experts say some days are simply more dangerous than others for drivers. Counterintuitively, car fatalities tend to peak in the summer months, despite more temperate weather conditions. Experts say that's because during the summer, roads are more congested, inexperienced teen drivers are on the road in higher numbers, there's more road construction, and high heat can lead to engine failure, tire blowouts, or other mechanical failure. Put all of this together, and you've got a recipe for disaster on the road.

So when are the roads considered most dangerous? The Insurance Institute for Highway Safety (IIHS) crunched the numbers using data from from motor vehicle crashes between 2015 and 2019, and has identified the six days of the year associated with the most fatalities. Read on to find out which day of the year is the single deadliest among them.
