Crashes took 32,367 lives in the U.S. in 2011.
By far the largest number of motor vehicle crash deaths are occupants of passenger vehicles including cars, minivans, pickups, SUVs, and cargo/large passenger vans. The likelihood of crash death varies markedly among these vehicle types according to size. Small/light vehicles have less structure and size to absorb crash energy, so more injurious forces can reach their occupants in crashes. People in lighter vehicles are at a disadvantage in collisions with heavier vehicles.

Pickups and SUVs are proportionally more likely than cars to be in fatal single-vehicle crashes, especially rollovers. However, pickups and SUVs generally are heavier than cars, so occupant deaths in SUVs and pickups are less likely to occur in multiple-vehicle crashes.
The following facts are based on analysis of data from the U.S. Department of Transportation's Fatality Analysis Reporting System (FARS) and The Polk Company's National Vehicle Population Profile.
A total of 28,896 passenger vehicle occupants died in 2007, 6 percent less than in 1975. However, the distribution of vehicle types among these crashes has changed. Car occupant deaths have declined 31 percent since 1975, while pickup occupant deaths have risen 55 percent and SUV occupant deaths are more than 10 times as high.
Passenger vehicle occupant deaths by vehicle type, 1975-2007
A total of 20,381 passenger vehicle drivers died in 2007, 6 percent less than in 2006 but 5 percent more than in 1975. Sixty-one percent of passenger vehicle driver deaths in 2007 were car drivers. However, the proportion of deaths involving pickup and SUV drivers is growing as the popularity of these vehicles increases.
Passenger vehicle occupant deaths represented 70 percent of the 41,059 motor vehicle crash deaths in 2007.
Frontal impacts accounted for 50 percent of passenger vehicle occupant deaths in 2007. Side impacts accounted for another 28 percent of passenger vehicle occupant deaths.
Forty-four percent of car occupant deaths in 2007 occurred in single-vehicle crashes and 56 percent occurred in multiple-vehicle crashes. In contrast, single-vehicle crashes accounted for 63 percent of both SUV occupant deaths and pickup occupant deaths.
Thirty-three percent of passenger vehicle occupants killed in 2007 were younger than 25.
Seventy-one percent of passenger vehicle occupants killed in 2007 were drivers; 71 percent of these drivers were males.
Computing driver death rates per million registered passenger vehicles allows for comparisons of fatal crash risk across vehicle groups. The computed rates reflect the influence of vehicle designs plus their patterns of use and the demographics of their drivers. Driver death rates are based on 1-3-year-old vehicles only so as to minimize the effects of vehicle aging. Rates based on fewer than 120,000 vehicle registrations are considered unreliable and are not included.
Since 1978, the overall rates of driver and occupant deaths per million registered vehicles have declined across all passenger vehicle types. Declines in death rates have been largest for SUV occupants.
For each vehicle type (car, pickup, SUV), the rates of driver deaths per million registered vehicles in 2007 were lower for the larger and heavier vehicles.
Driver deaths per million registered passenger vehicles 1-3 years old, 2007
Note: Pickups and SUVs are typically heavier than most passenger cars.
Multiple-vehicle crashes accounted for 33 driver deaths per million registered passenger vehicles in 2007, while there were 34 deaths per million in single-vehicle crashes. In single-vehicle crashes, pickups had the highest number of deaths per registered vehicle (59 per million) in 2007. In multiple-vehicle crashes, cars had the highest number of deaths per registered vehicle (38 per million), and SUVs had the lowest number of deaths per registered vehicle (20 per million).
Frontal impacts accounted for 18 driver deaths per million registered passenger vehicles in multiple-vehicle crashes in 2007 compared with 11 deaths per million in side impacts and 2 deaths per million in rear impacts.
Frontal impacts accounted for 17 driver deaths per million registered passenger vehicles in single-vehicle crashes in 2007 compared with 7 deaths per million in side impacts and fewer than 1 death per million in rear impacts.
A vehicle is classified as rolling over if it tips onto its side or roof at any time during the crash. The rollover may occur subsequent to a frontal or side impact with another vehicle or a fixed object. Many rollovers occur after a vehicle leaves the roadway and may lead to occupants being ejected from the vehicle, increasing the likelihood of a fatality.
A total of 10,182 passenger vehicle occupants died in rollover crashes in 2007. Twenty-two percent of these did not involve any other impact.
Crashes in which a vehicle rolled over accounted for 35 percent of passenger vehicle occupant deaths in 2007 (56 percent of single-vehicle occupant crash deaths and 13 percent of multiple-vehicle occupant crash deaths).
Since 1978 pickups and SUVs have a consistently higher percentage of rollover deaths than cars.
More than three-fourths of fatal rollovers are single-vehicle crashes.[ Error ] The remaining facts will concentrate on single-vehicle rollovers.
A total of 8,366 passenger vehicle occupants died in single-vehicle rollover crashes in 2007, 5 percent less than in 2006 but 6 percent more than in 1978.
Single-vehicle rollover crashes accounted for 47 percent of occupant deaths in SUVs in 2007, compared with 38 percent of occupant deaths in pickups and 21 percent in cars.
Since 1978, driver death rates for single-vehicle rollover crashes have declined across all passenger vehicle types, particularly for SUVs. Single-vehicle crashes involving rollover accounted for 19 driver deaths per million registered passenger vehicles in 2007.
