People often ask for one annual number, but truck-crash statistics answer different questions. A vehicle involved in a police-reported crash is not the same measure as a crash itself, an injured person, or a fatality.
For how many semi truck accidents per year, the closest current national benchmark is NHTSA’s estimate that 528,177 large trucks were involved in police-reported crashes in 2023. Those crashes involved an estimated 153,452 injured people and 5,472 deaths. The figures include commercial and non-commercial large trucks, not only semi-trucks, so they provide important context rather than a precise semi-truck-only total.
South Carolina records use different reporting rules and vehicle categories, which is why local figures cannot simply be substituted for the national estimate. The sections ahead separate these measures and explain what the national number actually counts.

How many semi truck accidents per year are recorded nationally?
The clearest current national answer is that an estimated 528,177 large trucks were involved in police-reported traffic crashes in 2023. That figure comes from the National Highway Traffic Safety Administration (NHTSA), which counts large trucks involved in reported crashes across the United States.
That number does not mean there were 528,177 unique semi-truck accidents. It counts large trucks, not crashes. A single crash can involve more than one large truck, and a large truck can be involved in a crash with passenger vehicles or other road users. The NHTSA category is also broader than semi-trucks alone. It includes medium and heavy trucks with a gross vehicle weight rating above 10,000 pounds, excluding buses and motor homes. The category includes commercial and non-commercial vehicles.
The same NHTSA report separates people injured and people killed from the vehicle-involvement total. In 2023, an estimated 153,452 people were injured in traffic crashes involving large trucks. These were people involved in the crashes, not a count of injury crashes. NHTSA also reported that 5,472 people were killed in crashes involving large trucks that year.
These measures answer different questions:
- 528,177: large trucks involved in police-reported crashes.
- 153,452: people estimated to have been injured in crashes involving large trucks.
- 5,472: people killed in crashes involving large trucks.
Because the national data covers a defined large-truck category, rather than semi-trucks exclusively, it should be used as a carefully labeled national reference point. For the underlying definitions and 2023 figures, see the NHTSA large-truck traffic safety fact sheet.
What do the national truck-crash numbers actually measure?
The answer depends on whether a source is counting crashes, vehicles, injured people, or fatalities. Those are related measures, but they are not interchangeable. A figure for large trucks involved does not mean the same number of unique crashes, and an injury total does not describe the number of injury-producing crashes.
For its national 2023 analysis, NHTSA defines a large truck as a medium or heavy truck with a gross vehicle weight rating above 10,000 pounds, excluding buses and motor homes. The category includes commercial and non-commercial vehicles, so it is broader than semi-trucks used in commercial freight. That definition matters when applying the data to a particular collision.
What each national truck-crash measure represents
| Measure | 2023 figure or source | What it counts | Limitation |
|---|---|---|---|
| Large trucks involved | 528,177 estimated. | Large trucks involved in police-reported traffic crashes nationwide. | Counts vehicles, not unique crashes; includes more than semi-trucks. |
| People injured | 153,452 estimated. | People injured in crashes involving large trucks. | Does not equal the number of injury crashes or injured truck occupants alone. |
| People killed | 5,472. | People killed in traffic crashes involving large trucks. | Counts fatalities, not fatal crashes or trucks involved. |
| Dataset type or limitation | FARS and CRSS. | FARS fatal-crash and fatality results are actual counts; CRSS non-fatal crash and injury results are estimates. | Different methods produce different kinds of totals. |
NHTSA provides the figures and definitions in its 2023 large-truck traffic safety fact sheet. FARS, the Fatality Analysis Reporting System, is the census used for fatal crashes and fatalities. CRSS, the Crash Report Sampling System, uses a representative sample of police-reported crashes to estimate national non-fatal crash and injury results.
FMCSA’s Large Truck and Bus Crash Facts, often shortened to LTBCF, is an annual report covering fatal, injury, and property-damage-only crashes. It compiles information from FARS, CRSS or the earlier NASS GES system, MCMIS, and FHWA Highway Statistics. Reading the dataset description alongside the number helps prevent a broad national estimate from being mistaken for a precise count of semi-truck crashes.
What does South Carolina truck-crash data show?
South Carolina’s 2023 statewide data provides important context, but it does not produce a single verified answer to how many semi-truck crashes occurred that year. The South Carolina Department of Public Safety (SCDPS) reported 145,761 total traffic collisions, 51,638 people injured in traffic collisions, and 1,047 people killed. Those figures cover collisions involving all vehicle types, not semi-trucks alone. The figures appear in the SCDPS 2023 Traffic Collision Fact Book.
The same fact book lists 87 fatalities from collisions involving a truck tractor in 2023. That number answers a narrower question: how many deaths occurred in collisions that involved that vehicle type. It is not a count of semi-truck crashes. It is not the number of people injured in semi-truck collisions, and it does not show how many truck tractors were involved in all reported crashes. Treating 87 as South Carolina’s annual semi-truck accident total would mix a fatality-by-vehicle-type measure with a crash-count measure.
SCDPS also explains why its totals have a defined reporting boundary. The statistics are compiled from Uniform Traffic Collision Report Forms, known as TR-310 reports, submitted by investigating officers. A collision on a public highway generally must be reported when it reaches the reportable property-damage threshold or results in an injury or death. Collisions on private property, or reports submitted on a form other than TR-310, are excluded from this dataset.
For that reason, the SCDPS figures are useful statewide context, but they should not be converted into an invented semi-truck crash total. A careful review should identify the source, year, vehicle category, reporting threshold, and outcome being counted before comparing South Carolina data with national large-truck estimates.
Why do annual semi-truck accident totals vary?
There is no single annual total because sources may be counting different things. One dataset may count large trucks involved in police-reported crashes, while another counts crashes, injured people, fatal crashes, or fatalities. Those are related measures, but they are not interchangeable. Vehicle definitions also matter. NHTSA’s “large truck” category covers medium and heavy trucks with a gross vehicle weight rating above 10,000 pounds, excluding buses and motor homes. It includes both commercial and noncommercial vehicles, so it is broader than semi-trucks alone. NHTSA explains the category and its limits.
The outcome being measured changes the level of certainty, too. FARS is a census of fatal crashes on public trafficways, so its fatal-crash and fatality results are actual counts. CRSS is a probability-based system used to estimate police-reported nonfatal crashes and injuries. FMCSA’s Large Truck and Bus Crash Facts combines sources including FARS, CRSS, MCMIS, and FHWA data. A total drawn from one system should not be added to or compared casually with a total from another.
Year-to-year comparisons require particular care. NHTSA states that vehicle-type classifications from 2020 forward are not comparable with classifications from 2019 and earlier because the classification method changed. FMCSA also notes that NHTSA retired GES and replaced it with CRSS in 2017. Comparisons between CRSS estimates beginning in 2016 and older GES estimates should be made cautiously.
Finally, police reporting and coverage rules can leave some collisions outside a dataset. For a meaningful comparison, identify the geography, vehicle definition, reporting source, year, and outcome first. Do not combine unlike numbers, or treat one unusually high or low year as proof of a long-term trend.
What evidence can matter after a semi-truck collision?
Crash statistics can show the scale of a problem, but they cannot explain what happened in one collision. After a semi-truck crash, the investigation may need to look beyond the driver. Depending on the circumstances, potentially relevant parties can include the trucking company, a maintenance provider, a cargo loader, or a manufacturer. Identifying those connections requires careful attention to the available records and the physical evidence.
Potentially useful records may include dispatch information, company safety records, driver logs, and electronic data from the truck. Electronic systems may contain information about vehicle operation or activity before the collision, but the availability and meaning of that data can vary. A record may provide context without proving that a particular person or company caused the crash.
Other details can help place the records in context. Photos of the vehicles and roadway, witness contact information, medical records, collision reports, and communications with insurers may help preserve a timeline. Keep original messages, photographs, and documents when possible. Do not assume that an early insurance account captures every important fact, especially while injuries are still developing.
Time can matter because some information may be held by a trucking company, maintenance business, carrier, or other third party. Promptly identifying potentially relevant sources can make it easier to request preservation of records before routine retention practices affect what remains available. That does not guarantee that a record exists or that it will support one side’s account.
For a closer look at practical preservation steps, read about preserving semi-truck crash evidence. Hammack Law Firm also explains South Carolina truck accident liability and the issues that can arise in commercial truck injury claims. These resources provide general information, while the relevant evidence in a particular South Carolina or Georgia collision depends on the facts and available records.
What should you do after a South Carolina truck crash?
A collision with a semi-truck can leave you dealing with pain, urgent medical decisions, insurance calls, and uncertainty about what happened. Focus first on safety and health. The annual statistics in this article provide context, but they do not determine who caused a particular crash or what evidence may be available.
- Get emergency care and follow medical guidance. Call 911 when emergency help is needed. If you can safely do so, tell medical providers about every symptom, including symptoms that appear later. Keep discharge papers, treatment instructions, prescriptions, bills, and notes about missed work.
- Report the collision and document what is safe to document. Cooperate with the responding officer and provide an accurate account without guessing. From a safe location, photograph vehicle positions, visible damage, roadway conditions, traffic controls, and injuries. Write down witness names and contact information. Never step into traffic or interfere with emergency operations to get a photograph.
- Preserve communications and records. Save insurance messages, emails, letters, photographs, medical records, and repair documents. Do not delete texts or social-media posts related to the collision. Truck cases may involve dispatch information, safety records, driver logs, and electronic truck data, so promptly preserving semi-truck crash evidence can matter.
- Avoid assumptions about fault. Do not speculate about speed, distraction, loading, maintenance, or the actions of another driver. Multiple parties may need to be considered, including a driver, trucking company, maintenance provider, cargo loader, or manufacturer.

Frequently Asked Questions
How common are semi-truck accidents each year?
The closest current national measure is NHTSA’s estimate that 528,177 large trucks were involved in police-reported traffic crashes in 2023. That category is broader than semi-trucks: it includes medium and heavy trucks over 10,000 pounds, commercial and non-commercial vehicles, and is not a count of unique crashes. In those large-truck crashes, an estimated 153,452 people were injured and 5,472 people were killed. See the NHTSA 2023 large-truck report for the definitions and methodology.
Does the national number count crashes or trucks?
It counts large trucks involved in police-reported crashes, not necessarily one truck accident per number. A single collision can involve more than one large truck, and the figure also includes crashes that resulted in property damage, injury, or death. Fatality results from NHTSA’s Fatality Analysis Reporting System are actual counts, while nonfatal crash and injury results from the Crash Report Sampling System are estimates. Those differences matter when interpreting the totals.
Why can South Carolina totals differ from national semi-truck statistics?
South Carolina figures use a different geography, reporting system, and vehicle measure. The 2023 South Carolina Department of Public Safety Fact Book reports 145,761 total collisions, 51,638 traffic-collision injuries, and 1,047 people killed statewide. It also lists 87 fatalities in collisions involving a truck tractor. That is a fatality measure, not the number of all truck-tractor crashes or all semi-truck injuries. The data come from TR-310 reports, with reporting limits described in the SCDPS 2023 Fact Book.
What records may matter after a semi-truck collision?
Depending on the circumstances, useful records may include dispatch information, safety records, driver logs, and electronic truck data. Photos, medical records, witness information, and communications may also help preserve what happened. These materials do not automatically establish fault, but keeping them can help a lawyer evaluate the collision and identify which parties may need investigation.
