Saturday is the deadliest day of the week to drive, and the late afternoon and evening hours are the deadliest time.

What is The Deadliest Day of the Week to Drive?

Saturday is the deadliest day of the week to drive. National Safety Council analysis of NHTSA data found fatal crashes peak on weekends, with Saturday the highest. Nonfatal crashes run higher on weekdays and top out on Friday.

Deadliest Time of Day to Drive

The 6 p.m. to 9 p.m. window is the deadliest three-hour block, accounting for about 17% of all traffic deaths. Roughly a third of fatalities happen between 3 p.m. and 9 p.m., when the evening commute, fading daylight, and rising impairment overlap. Alcohol involvement climbs sharply after dark and peaks between midnight and 3 a.m., which is why weekend nights are the worst.

Deadliest Single Days

New Year's Day and the Fourth of July rank as the two deadliest days on the calendar. On New Year's Day, alcohol-impaired fatal crashes run nearly 90% above a normal day, with most deaths clustered between midnight and 4 a.m. as partygoers head home.

The Fourth of July is the deadliest holiday overall. From 2020 through 2024, more than 2,700 people died during the July 4th holiday period, and 38% of the drivers killed were legally drunk, the highest impaired share of any major holiday.

Labor Day and Memorial Day weekends follow close behind. Most of the worst individual days each year fall in summer, when travel, long weekends, and drinking overlap.
