Arizona saw more than 120,000 crashes in 2021. Data says this day of the week was most dangerous

Data from more than 121,000 crashes in Arizona provides insight on the worst times to drive.

PHOENIX — Last year, Arizona saw more than 120,000 crashes and more than 1,100 deaths on our roadways. A staggering statistic that raises an eyebrow to anyone who reads it.

But as you look closer, another alarming trend takes shape. One day out of the week tends to be more dangerous than the others.

On Fridays, the daytime hours saw more than 20,000 crashes and more than 200 deaths.

The day combines the worst of two worlds.

You have the rush hour bumper-to-bumper traffic that Arizona Department of Transportation statistics show lead to the most accidents and the late night, weekend dangers.

“Night time, we generally see a significant proportion of fatalities at night during dark hours.” Brendan Russo, a professor at NAU, said. “Roads aren't congested, people can drive faster. There is also an alcohol issue.”

According to data from ADOT, while alcohol is involved in less than 5 percent of all crashes, it played a role in more than 20 percent of all deaths.

It's a surprising stat that drivers certainly should take note of. And always remember to stay safe on the roads.
