Large Truck and Bus Crash Facts 2016

This online edition of Large Truck and Bus Crash Facts provides Excel files containing data for each of the report's data tables and graphs. A printable version of the complete report is also available.

Note: Data Revisions. FHWA implemented an enhanced methodology for estimating registered vehicles and vehicle miles traveled by vehicle type beginning with data from 2007. As a result, involvement rates may differ, and in some cases significantly, from earlier years. Separately, NHTSA retired GES in 2017, replacing it with CRSS. CRSS builds on GES, beginning with data for 2016. Although the two systems are both samples of police-reported crashes involving all types of motor vehicles, CRSS includes a more efficient and flexible sample using updated traffic and demographic information. As a result, comparisons of 2016 CRSS estimates with older GES estimates should be performed with caution.

Introduction

This annual edition of Large Truck and Bus Crash Facts contains descriptive statistics about fatal, injury, and property damage only crashes involving large trucks and buses in 2016. Selected crash statistics on passenger vehicles are also presented for comparison purposes.

Data Sources

The information in this report was compiled by the Analysis Division of the Federal Motor Carrier Safety Administration (FMCSA). The major sources for the data are described below:

  • Fatality Analysis Reporting System (FARS): FARS, maintained by the National Highway Traffic Safety Administration (NHTSA), is a census of fatal crashes involving motor vehicles traveling on public trafficways. FARS is recognized as the most reliable national crash database, but it contains information only on fatal crashes. A large truck is defined in FARS as a truck with a gross vehicle weight rating (GVWR) greater than 10,000 pounds. A bus is defined in FARS as any motor vehicle designed primarily to transport nine or more persons, including the driver. The 2016 FARS data are considered preliminary for one year. This additional time provides the opportunity for submission of important variable data requiring outside sources, which may lead to changes in the final counts. The updated final counts for 2015 are reflected in this report. Updated final counts for 2016 will be reflected in the 2017 annual report. For more information on FARS, go to https://www.nhtsa.gov/research-data/fatality-analysis-reporting-system-fars.
  • General Estimates System (GES): GES, also maintained by NHTSA, is a probability-based nationally representative sample of police-reported fatal, injury, and property damage only crashes. The data from GES yield national estimates, calculated using a weighting procedure, but cannot give State-level estimates. Because GES is a sample of motor vehicle crashes, the results generated are estimates rounded to the nearest one thousand; however, associated percentages and rates are based on the unrounded data. The GES definitions of a large truck and a bus are the same as the FARS definitions. NHTSA retired GES in 2017 and replaced it with the Crash Report Sampling System. For more information on GES, go to https://www.nhtsa.gov/research-data/national-automotive-sampling-system-nass.
  • Crash Report Sampling System (CRSS): NHTSA’s newly established CRSS builds on GES, beginning with data for 2016. Although the two systems are both samples of police-reported crashes involving all types of motor vehicles, CRSS includes a more efficient and flexible sample using updated traffic and demographic information. As a result, comparisons of 2016 CRSS estimates with older GES estimates should be performed with caution. To learn more about CRSS, visit https://www.nhtsa.gov/national-center-statistics-and-analysis-ncsa/crash-report-sampling-system-crss#crash-report-sampling-system-crss-data-files.
  • Motor Carrier Management Information System (MCMIS) Crash File: The MCMIS Crash File, maintained by FMCSA, contains data on trucks and buses in crashes that meet the SAFETYNET recommended threshold. A SAFETYNET reportable crash must involve a truck, used for commercial purposes, with a GVWR or gross combination weight rating greater than 10,000 pounds; a commercial bus designed to transport nine or more persons, including the driver; or any vehicle carrying hazardous material that requires placarding, regardless of the vehicle’s weight. The crash must result in at least one fatality, at least one injury involving immediate medical attention away from the crash scene, or at least one vehicle disabled as a result of the crash and transported away from the crash scene. The crashes are reported by the States to FMCSA through the SAFETYNET computer software. The MCMIS Crash File is intended to be a census of trucks and buses involved in fatal, injury, and towaway crashes; however, some States do not report all FMCSA-eligible crashes, and some report more than those that are eligible. FMCSA continues to work with the States to improve data quality and reporting of eligible large truck and bus crashes to the MCMIS crash file.

FARS, GES, CRSS, and MCMIS describe the events and details of motor vehicle crashes, but they do not include data on crash causation or fault.

  • Highway Statistics: Highway Statistics is an annual publication of the Office of Highway Policy Information of the Federal Highway Administration (FHWA). State agencies report the data, ranging from driver licensing to highway finance, and FHWA aggregates them to get national totals. This report takes vehicle miles traveled (VMT) and vehicle registrations from Table VM-1 of Highway Statistics, "Annual Vehicle Distance Traveled in Miles and Related Data." Readers are warned to be careful of crash rate data based on the VMT numbers from FHWA. Beginning with data for 2007, FHWA implemented an enhanced methodology for estimating registered vehicles and VMT by vehicle type. The new methodology did not change the total VMT, but it did make a large difference in the number of miles traveled attributed to large trucks and buses. As a result, it would be misleading to cite large truck and bus data trends that encompassed both the years before 2007 and the years following. For more information on VMT data, go to www.fhwa.dot.gov/policyinformation/statistics/2016.

Organization of the Report

The report is organized into four chapters: Trends, Crashes, Vehicles, and People. The Trends chapter shows data for 2016 in the context of available historical data for past years. In the other chapters, the 2016 data are shown in different ways, according to what is being counted. Three-year trends in fatal crashes are presented for historical perspective when appropriate. The Crashes chapter counts numbers of crashes; the Vehicles chapter counts vehicles in crashes; and the People chapter counts persons of all types involved in crashes. Four different types of counts are shown:

  • Crashes: Numbers of crashes involving various vehicle types.
  • Vehicles in Crashes: Numbers of vehicles involved in crashes. These counts may be larger than the number of crashes (fatal, injury, or property damage only), because more than one vehicle may be involved in a single crash.
  • People in Crashes: Numbers of people killed or injured in crashes. These counts generally are larger than the number of crashes (fatal or injury), because more than one person may be killed or injured in a single crash. People killed or injured may be occupants of a large truck or bus, occupants of another vehicle, or nonmotorists (pedestrians or pedalcyclists).
  • Drivers in Crashes: Numbers of vehicle drivers involved in crashes. These counts generally are equal to the numbers of vehicles involved in crashes.

Trends

The tables in this chapter present crash statistics for large trucks and buses over time. Fatal crash statistics generally are available from 1975, the first year of FARS data, through 2016. In some cases, such as for alcohol involvement, data are available only from 1981 or 1982 through 2016. Nonfatal crash statistics are presented for 1996 through 2016. From 1996 through 2015, they are based on GES data, but starting with 2016, they are based on the new CRSS data. Although the two systems are both samples of police-reported crashes involving all types of motor vehicles, CRSS includes a more efficient and flexible sample using updated traffic and demographic information. As a result, comparisons of 2016 CRSS estimates with older GES estimates should be performed with caution. The statistics shown in this chapter represent crashes, vehicles, drivers, fatalities, and injuries in crashes. Below is a summary of some of the trend information in this section:

  • In 2016, 4,440 large trucks and buses were involved in fatal crashes, a 2-percent increase from 2015. Although the number of large trucks and buses in fatal crashes has increased by 29 percent from its low of 3,432 in 2009, the 2016 number is still 15 percent lower than the 21st-century peak of 5,231 in 2005. From 2015 to 2016, large truck and bus fatalities per 100 million vehicle miles traveled by all motor vehicles increased by 1.9 percent, from 0.141 to 0.144.
  • There was a 34-percent decrease in the number of fatal crashes involving large trucks or buses between 2005 and 2009, followed by an increase of 28 percent between 2009 and 2016. From 2015 to 2016, the number of fatal crashes involving large trucks or buses increased by 6 percent.
  • The number of injury crashes involving large trucks or buses decreased steadily from 102,000 in 2002 to 60,000 in 2009 (a decline of 41 percent). Since then, it increased 62 percent to 97,000 in 2015. In 2016, there were an estimated 119,000 injury crashes, based on NHTSA's new CRSS data collection.
  • On average, from 2006 to 2016, intercity buses accounted for 13 percent, and school buses and transit buses accounted for 40 percent and 34 percent, respectively, of all buses involved in fatal crashes.
  • Over the past year (from 2015 to 2016):
  • The number of large trucks involved in fatal crashes increased by 3 percent, from 4,074 to 4,213, and the large truck involvement rate (large trucks involved in fatal crashes per 100 million miles traveled by large trucks) remained constant at 1.46.
  • The number of buses involved in fatal crashes decreased from 263 to 227, a decrease of 14 percent.

Crashes

This chapter contains information on the circumstances of large truck crashes. Below is a summary of some of the information in this section:

  • Of the approximately 475,000 police-reported crashes involving large trucks in 2016, there were 3,864 (0.8 percent) fatal crashes and 104,000 (22 percent) injury crashes.
  • Single-vehicle crashes (including crashes that involved a bicyclist, pedestrian, nonmotorized vehicle, etc.) made up 22 percent of all fatal crashes, 14 percent of all injury crashes, and 24 percent of all property damage only crashes involving large trucks in 2016. The majority (62 percent) of fatal large truck crashes involved two vehicles.
  • Fatal crashes involving large trucks tend to occur in rural areas and on Interstate highways. Approximately 61 percent of all fatal crashes involving large trucks occurred in rural areas, 27 percent occurred on Interstate highways, and 15 percent fell into both categories by occurring on rural Interstate highways.
  • Thirty-seven percent of all fatal crashes, 23 percent of all injury crashes, and 20 percent of all property damage only crashes involving large trucks occurred at night (6:00 pm to 6:00 am).
  • The vast majority of fatal crashes (84 percent) and nonfatal crashes (88 percent) involving large trucks occurred on weekdays (Monday through Friday).
  • Collision with a vehicle in transport was the first harmful event (the first event during a crash that resulted in injury or property damage) in 73 percent of fatal crashes involving large trucks, 83 percent of injury crashes involving large trucks, and 75 percent of property damage only crashes involving large trucks.
  • Overturn (rollover) was the first harmful event in 5 percent of all fatal crashes involving large trucks and 2 percent of all nonfatal crashes involving large trucks.
  • In 2016, 27 percent of work zone fatal crashes and 8 percent of work zone injury crashes involved at least one large truck.
  • There were 12.0 fatal large truck crashes per million people in the United States in 2016, a 13-percent increase from 10.6 in 2010.
  • In 2016, on average, there were 1.12 fatalities in fatal crashes involving large trucks. In 91 percent of those crashes, there was only one fatality. The majority, 83 percent, of fatalities were not occupants of the large truck.

Detailed List of Tables from Chapter 2 (Crashes):

Vehicles

This chapter presents information on large trucks involved in fatal, injury, and property damage only crashes. Some of the data in this chapter come from the MCMIS Crash File, which contains data on trucks and buses in crashes that meet the SAFETYNET crash severity thresholds. MCMIS data are used for the tables on crashes by vehicle configuration (Vehicles Table 2), cargo body type (Vehicles Table 4), gross vehicle weight rating (Vehicles Table 6), hazardous materials cargo (Vehicles Table 9), and hazardous materials released (Vehicles Table 11). SAFETYNET nonfatal crashes tend to be more serious than GES and CRSS nonfatal crashes, because the SAFETYNET threshold requires at least one injury involving immediate medical attention away from the crash scene, or at least one vehicle disabled as a result of the crash and transported away from the crash scene. Below is a summary of some of the vehicle information in this section:

  • In 2016, 4,213 large trucks were involved in fatal crashes. According to MCMIS, 55,633 large trucks were involved in injury crashes, and 99,911 were involved in towaway crashes.
  • Hazardous materials (HM) cargo was present on 4 percent of the large trucks involved in fatal crashes and 2 percent of those in nonfatal crashes. HM was released from the cargo compartments of 16 percent of the placarded trucks in fatal and nonfatal crashes. Flammable liquids (gasoline, fuel oil, etc.) accounted for 60 percent of the HM releases from cargo compartments in fatal crashes and 52 percent of the HM releases in nonfatal crashes.
  • "Collision with vehicle in transport" was recorded as the most harmful event for 74 percent of the large trucks involved in fatal crashes and for 76 percent of the large trucks involved in nonfatal crashes.
  • The critical precrash event for 73 percent of the large trucks in fatal crashes was another vehicle, person, animal, or object in the large truck’s lane or encroaching into it. Twently-three percent of the large trucks in fatal crashes had critical precrash events of their own movement or loss of control.
  • Singles (truck tractors pulling a single semi-trailer) accounted for 62 percent of the large trucks involved in fatal crashes in 2016; doubles (tractors pulling two trailers) made up 3 percent of the large trucks involved in fatal crashes; and triples (tractors pulling three trailers) accounted for less than 0.1 percent of all large trucks involved in fatal crashes.
  • Vehicle-related factors were coded for 5 percent of the large trucks involved in fatal crashes and 3 percent of the passenger vehicles involved in fatal crashes. "Other Working Vehicle" and "Tires" were the most common vehicle-related factors for large trucks in fatal crashes, at 2 percent and 1 percent, respectively. "Tires" was the most frequently coded vehicle-related factor for passenger vehicles in fatal crashes, at 1 percent.

People

This chapter contains information on drivers of large trucks and buses in fatal, injury, and property damage only crashes and on people killed or injured in large truck crashes. Some statistics for passenger vehicle drivers are also listed, to allow comparisons. It is important to note that the number of large truck or bus drivers in crashes is not exactly equal to the number of large trucks or buses in crashes, because for some crashes no driver information is provided. Below is a summary of some of the information in this section:

  • Of the 4,152 drivers of large trucks involved in fatal crashes in 2016, 234 (6 percent) were 25 years of age or younger, and 235 (6 percent) were 66 years of age or older. In comparison, 6 (3 percent) of the 226 drivers of buses in fatal crashes were 25 years of age or younger, and 25 (11 percent) were 66 years of age or older.
  • In 2016, 13 percent (662) of large truck occupants in fatal crashes were not wearing a safety belt, of which 285 (43 percent) were killed in the crash. In contrast, only 307 (8 percent) of the 3,849 large truck occupants wearing safety belts in fatal crashes were killed. Ten percent of the 4,152 drivers of large trucks involved in fatal crashes (396) were not wearing a safety belt at the time of the crash.
  • In 2016, at least one driver-related factor was recorded for 32 percent of the large truck drivers in fatal crashes, compared to 55 percent of the passenger vehicle drivers in fatal crashes. "Speeding of Any Kind" was the most frequent driver-related factor for drivers of both vehicle types; "Distraction/Inattention" was the second most common for large truck drivers, and "Impairment (Fatigue, Alcohol, Illness, etc.)" was the second most common for passenger vehicle drivers.
  • There were 722 large truck occupant fatalities in 2016, a 9-percent increase from the 665 fatalities in 2015. In 2016, 88 percent of these occupant fatalities were drivers of large trucks, and 11 percent were passengers in large trucks.
