Think highways are safe?
It’s time to think again.
Every year, thousands of lives are disrupted or ended by commercial truck accidents.
In fact, in the U.S. alone, 5,788 people died in traffic crashes involving large trucks in 2021, a 17% increase from the 4,945 fatalities in 2020.
Behind every one of these numbers is a human story and an urgent call for better safety practices, policies, and awareness.
In this report, we’ll break down the most recent, verified commercial truck accident statistics.
Key Truck Accident Statistics at a Glance (Quick Snapshot)
- 5,472 people were killed in large truck crashes in 2023, a drop of 8% from 2022, but still up over 40% compared to a decade ago.
- In 2023, 153,452 people were injured in crashes involving large trucks, representing a 4.4% decrease from the previous year.
- Large trucks were involved in 9% of all fatal vehicle crashes in 2023, despite representing a much smaller share of vehicles on the road.
- Over 5,375 fatal crashes involving large trucks occurred in 2023, representing a slight decline but still far above early 2010s levels.
- Commercial trucks account for 10% of total vehicle miles traveled nationwide, meaning their crash rates per mile are disproportionately high.

How Many Commercial Truck Accidents Happen Each Year?
Crash data can feel abstract until it hits home.
For U.S. road users, especially those driving near commercial trucks every day, these numbers are anything but theoretical.
In 2023, there were approximately 156,500 crashes involving commercial trucks (those over 10,000 lbs GVWR). That includes everything, such as fatal injury, property damage. To put it simply, that means a major incident with a truck roughly every three minutes.
Of those, 4,807 were fatal crashes, an 11% drop compared to 2022. That’s still nearly 100 families grieving every week.
Likewise, around 71,500 commercial truck crashes resulted in injuries, though thankfully, that number dipped slightly from the previous year.
Still, that’s an urgent reminder: injuries involving trucks affect lives, livelihoods, and futures.
Did You Know? A fully loaded tractor-trailer traveling at 65 mph can take up to 525 feet to stop, that’s nearly two football fields, compared to just 316 feet for a typical 4,000-lb passenger vehicle under the same conditions.

Who Is Most at Risk?
When a commercial truck crash happens, it’s not always the truck driver who’s in the worst condition. Here’s how the numbers shake out:
- In 2023, a total of 5,472 people tragically lost their lives in crashes involving large commercial trucks.
-
- 70% (approximately 3,837 people) were occupants of other vehicles.
- 18% (about 961 people) were truck occupants.
- 12% (around 674 people) were non-occupants, such as pedestrians, bicyclists, or other vulnerable road users.
-
- Fast-forward to 2024, and the latest data from FMCSA’s MCMIS shows:
- 167,425 reported semi-truck crashes (all severity levels), a 2.6% decline from 2023’s numbers.
- Approximately 74,078 people were injured in those crashes.
- There were 4,602 fatalities

Timing plays a big part.
Knowing when and where these crashes happen helps drivers, planners, and policymakers focus prevention efforts where it counts.
When Crashes Occur
- In 2023, 76% of fatal truck-involved crashes occurred during weekday daytime hours (Mon–Fri, 6 a.m.–5:59 p.m.), according to NHTSA.
State-Level Risk by Fatal Crash Involvement
- Based on NSC’s 2023 data, the states with the highest share of large-truck-involved fatal crashes are:
- Wyoming (22%)
- New Mexico (20%)
- North Dakota (18%)
- Idaho (17%)
- Nebraska (16%).
- States with the lowest shares include
- Hawaii and D.C. (2%)
- Rhode Island (3%)
- New Hampshire, Massachusetts, and Delaware (each at 5%).
Did You Know? In 2023, over 73% of all fatal large truck crashes involved a tractor-trailer rather than a single-unit truck.

Texas: Houston, Dallas, San Antonio, Fort Worth, and Austin Top The Crash List (2023)
When you think of epic highway systems and freight corridors… think Texas. The numbers from 2023 speak volumes:
- 35,827 commercial truck crashes statewide, that’s nearly 98 incidents per day.
- 613 people died in those crashes, making up about 1.71% of all truck collisions in the state.
- Houston, Dallas, and San Antonio carry much of that load, especially along I-10, I-35, and I-45.

California: High Stakes, High Traffic (2023)
California shoulders some of the toughest trucking numbers in the nation:
- 392 fatalities resulted from large truck crashes in 2023, second only to Texas.
- On California highways, there were about 387 fatal truck accidents, plus over 5,900 injuries.

Top 7 States by Large-Truck Crash Fatalities (2023)
Although Texas, California, and Florida top the nation in sheer numbers of large-truck crash fatalities, other states also have hidden dangers when you account for the proportion of crashes involving trucks.
In 2023, Texas led with 730 fatalities, a reflection of its vast freight corridors like I-10, I-35, and I-45.
California followed with 392, while Florida recorded 341, each state combining dense population with heavy truck traffic.
The percentages tell a different story for rural states: Wyoming (22%), New Mexico (20%), North Dakota (18%), and Idaho (17%) may see fewer crashes overall, but commercial trucks are involved in a disproportionately high share of fatal collisions.
| Rank | State | Fatalities (Large-Truck Crashes, 2023) |
| 1 | Texas | 730 |
| 2 | California | 392 |
| 3 | Florida | 341 |
| 4 | Wyoming¹ | (22 % involvement rate) |
| 5 | New Mexico¹ | (20 % involvement rate) |
| 6 | North Dakota¹ | (18 % involvement rate) |
| 7 | Idaho¹ | (17 % involvement rate) |
| U.S. Total | 5,472 fatalities |

Large-Truck Occupant Fatalities: Rural vs. Urban (2023)
In 2023, 71% of large-truck occupant fatalities occurred in rural areas, where factors like higher speeds, lower enforcement, and delayed medical response amplify crash severity.
Urban areas accounted for just 29% of these fatalities, even though they house more traffic and intersections.
| Area Type | Large Truck Occupant Deaths | Percentage of Total |
| Rural | 502 | 71% |
| Urban | 205 | 29% |
Did You Know? Large commercial trucks have a low rollover threshold, around 0.2 g, compared to over 1 g for passenger cars, due to their taller center of gravity.
That means even modest turns or shifts in load at everyday highway speeds can trigger a rollover.

Where Do Fatal Large‑Truck Crashes Happen Most? (2023)
The data reveals that in 2023, more than half of fatal commercial-truck crashes occurred on rural roads.
About 26% occurred on highway interstates, where high-speed freight movement intersects with various types of traffic.
While most crashes (around 62%) happened during daylight hours, a significant 5.2% occurred in work zones, areas demanding heightened driver focus.
Beyond the raw percentages, this shows the need for location-specific safety interventions.
| Location Type / Timing | % of Fatal Large‑Truck Crashes |
| Rural Areas | 55% |
| Highway Interstates | 25% |
| Non‑Interstate Major Roads | 51% |
| Work Zones | 5% |
| Daytime (Weekday Daytime: 6 a.m.–5:59 p.m.) | 70% |

What Causes Most Commercial Truck Accidents?
Understanding why truck crashes happen is just as important as knowing who is affected.
The most comprehensive federal findings come from the Large Truck Crash Causation Study (LTCCS). It was conducted by the FMCSA and NHTSA between 2001 and 2003.
This in-depth investigation examined hundreds of variables per crash and remains the foundation for what we know today.
Top Factors: LTCCS Findings
Driver-related issues were the most common:
- Fatigue and drowsiness, especially on long hauls, played a significant role.
- Speeding and aggressive driving, particularly in challenging conditions or on curves, raised crash risk.
- Driver distraction from mobile devices to in-cab adjustments was another frequent contributor.
Vehicle-related problems also mattered:
- Brake issues (worn, overheated, or improperly adjusted) extended stopping distances and worsened crash severity.
- Tire blowouts and other mechanical failures increased the likelihood of losing control.
Environmental factors further influenced crash likelihood:
- Adverse weather and low visibility impaired reaction times.
- Roadway geometry (sharp curves, narrow lanes) and unfamiliar routes reduced driver margin for error.
Did You Know? In 2021, FMCSA inspections found that over 180,000 driver log violations, including falsified or incomplete logs, occurred out of approximately 2.77 million inspections.
That’s a violation rate of 6.5%, suggesting significant issues with Hours-of-Service enforcement.

Takeaway:
Bottom line?
The more we understand where and why these crashes happen, the better we can keep both commercial trucks and everyone around them safe.
Certain states consistently record higher crash numbers, often due to major freight corridors, dense urban traffic, and long-haul routes. These incidents represent significant economic costs, lost productivity, and, most importantly, lives impacted.
