Deadliest Behaviors By Time of Day
The data shows these risk factors do not operate on the same clock. Alcohol is overwhelmingly a nighttime problem, with 56% of late night deaths between 12 and 3 AM involving an impaired driver, compared with just 12.5% at midday, a more than fourfold difference. Distraction runs the opposite direction, actually more common at midday (10.5%) than late at night (8.0%), likely tied to daytime commuting, errands, and phone use during waking hours. Speeding is the one constant threat, factoring into roughly 3 in 10 fatal crashes whether it's late night (39.7%) or midday (28.1%), meaning no time of day is truly safe from it.
