When Do Most Car Accidents Happen?

Most car accidents in Texas happen during the weekday evening commute. The crashes most likely to turn deadly tend to occur later, after traffic has eased. TxDOT data shows when the roads are busiest and when crashes carry the greatest risk.

The TxDOT Data Behind These Crash Patterns

The figures in this guide come from the Texas Department of Transportation’s Crash Records Information System, the state database built from Texas Peace Officer’s Crash Reports. The primary source is TxDOT’s Texas Motor Vehicle Traffic Crash Facts, Calendar Year 2025, which includes reports processed through April 7, 2026.

The 2025 figures were also compared with TxDOT’s 2024 data to identify patterns that continued across both years. Calendar year 2025 is the most recent complete dataset available. Individual records can be searched through TxDOT’s CRIS Query tool.

The same data also reveals significant differences across the state, including the Texas counties with the highest numbers of deadly crashes.

The Hours When Crashes Happen Most Often

The busiest hour on Texas roads is 5:00 to 5:59 PM. TxDOT’s hour-by-hour crash data for CY2025 recorded 43,731 crashes statewide in that single hour, the weekday evening commute peak. 

The single hour with the most fatal crashes was 8:00 to 8:59 PM, with 222 fatal crashes, two to three hours after the volume peak. TxDOT’s published counts also show how the percentage of fatal crashes changes throughout the day. The overnight hours from roughly midnight to 5 AM carry the highest share, between about 1.5% and 2.0%, compared to roughly 0.3% during the 5 PM peak.

That’s four to six times higher, even with far fewer cars on the road overnight. This comparison uses our calculation based on TxDOT’s published hourly counts, rather than a figure reported directly by the agency.

Alcohol contributes to the overnight risk. TxDOT’s DUI-related fatal crash data shows 2:00 to 2:59 AM as the single highest hour for alcohol-related fatal crashes in CY2025, with 108 crashes, more than any other hour of the day.

The prior year shows the same pattern. In CY2024, the peak volume hour was also 5:00 to 5:59 PM, and the peak fatal hour fell from 9:00 to 9:59 PM.

The exact hour changes, but the highest number of fatal crashes consistently falls between 8 PM and 10 PM, a few hours after crash volume peaks. These hourly figures also contribute to Texas’s average daily crash totals.

The Days That Carry the Most Risk

Friday is the busiest day of the week on Texas roads, with 87,812 crashes in CY2025, about 16.3% of the year’s total. Friday’s fatal rate, 0.60%, sits close to the weekday average.

Saturday had the most fatal crashes of any single day, 621. Saturday and Sunday both carry the highest fatal rates of the week, 0.85% and 1.02% respectively, roughly double the 0.52% to 0.56% fatal rate seen Monday through Thursday.

The highest-risk hour-and-day combination was Sunday from 2:00 to 2:59 AM. That figure reflects crashes occurring after midnight following Saturday night activities rather than a broader risk associated with daytime driving on Sunday.

TxDOT’s CY2024 hour-and-day report shows a similar pattern. Friday had the most crashes, Saturday had the most fatal crashes, and Saturday and Sunday had the highest fatal crash rates.

How Crash Risk Shifts Through the Year

October was the busiest month for crashes in CY2025, with 50,494 crashes recorded in TxDOT’s monthly crash breakdown. March was the deadliest month, with 342 fatal crashes, narrowly ahead of August’s 337.

The busiest month and the deadliest month were not the same, echoing the pattern seen by hour and day. TxDOT’s CY2024 monthly report shows October itself was the deadliest month that year, with 347 fatal crashes.

The comparison shows that the deadliest month can change from year to year, and the month with the most crashes is not always the month with the most fatal crashes.

What These Patterns Mean If You’re Hurt in a Texas Car Crash

TxDOT’s data shows several consistent patterns: 

• Crashes are most likely during the weekday evening commute, roughly 4 to 6 PM.
• The odds that a crash turns fatal are highest overnight, roughly midnight to 5 AM, and on weekend nights following Friday and Saturday driving.
• Alcohol is a recurring factor in the deadliest overnight hours, especially around 2 to 3 AM.
• TxDOT’s public data splits crashes into fatal and non-fatal only, with no hour-by-hour breakdown of injury severity available. “Peak injury hours” in this guide refers to the fatal-crash data, the closest available proxy.
• Texas recorded 3,769 traffic fatalities and 3,476 fatal crashes statewide in CY2025.

The time of the crash does not change the steps you should take afterward. After a Texas car accident, protecting your health, documenting the scene, and preserving evidence remain important whether the collision happened at 5 PM on a Friday or 2 AM on a Sunday.
