For much of the 20th century and the early years of the 21st century, U.S. roads gradually became safer for pedestrians. However, this trend reversed around the year 2009. Since then, the number of pedestrians killed in traffic accidents has increased by approximately 75%, a development that has concerned the researchers responsible for road safety and public administrations.

Various factors have been identified as possible causes of this increase, such as distraction caused by mobile phones, drug-impaired driving, or the general increase in traffic. However, an investigation based on federal records and automotive industry data points to an element that has often gone unnoticed: the steady growth in the size of vehicles, especially SUVs and pickups.
According to this analysis, current vehicles are considerably larger and taller than they were two decades ago. This change is not just an aesthetic or comfort issue, but it has direct implications for pedestrian safety. Researchers estimate that between 200 and 400 annual deaths could be related to this increase in dimensions. Overall, this would represent approximately 10% of the recent increase in fatalities among pedestrians.
Experts identify two main reasons that explain why large vehicles are more dangerous. The former is the height of the hood. In traditional cars, an impact usually occurs in the leg area, often causing the body to be projected onto the vehicle. In contrast, SUVs and pickups have much higher hoods, which strike directly at the torso or even the head of the pedestrian. This type of impact significantly increases the severity of injuries and raises the risk of the person being dragged or ending up under the vehicle’s wheels.
The second cause is the reduction of visibility. As vehicles have grown, so have their blind spots. Tests conducted with three-dimensional scanners on some of the most popular models in the North American market show that areas with no direct visibility for the driver are now much larger than in equivalent models from the 1990s or early 2000s. This makes it difficult to detect the presence of pedestrians, especially children, short individuals, or users who are very close to the vehicle.
Several real cases described in the study illustrate the consequences of this issue. In some fatal accidents, drivers claimed not to have seen the victim before the impact. Subsequent reconstructions concluded that structural elements of the vehicle, such as the raised hood, the mirrors, or the side pillars, had significantly limited the field of view.
Automakers argue that new driver assistance systems can compensate for these limitations. Technologies such as automatic emergency braking or pedestrian detection are designed to reduce the risk of collisions. However,
different studies have shown that these systems do not work perfectly in all situations. Factors such as adverse weather, shadows, high speeds, or the presence of children can reduce their effectiveness.
Beyond technical issues, the expansion of SUVs and pickups also responds to economic and cultural reasons. These vehicles generate very high profit margins for manufacturers, who have progressively reduced the production of saloons and other conventional passenger cars. In parallel, advertising campaigns have associated large vehicles with concepts such as safety, prestige, strength, or personal success. This message has contributed to consolidating the perception that a larger vehicle is a better option for many families.
Road safety specialists insist that the size of vehicles is not the only cause of the increase in pedestrian deaths. Urban design, traffic speed, driver distraction, and other factors remain determinants. However, there is increasing evidence that the trend towards taller and bulkier vehicles has increased the risk for the most vulnerable road users.
In conclusion, the growth of SUVs and pickups poses a significant road safety challenge. Despite technological advancements, the combination of higher hoods and larger blind spots increases the severity of accidents and hinders the detection of pedestrians. This phenomenon highlights the need to continue researching and developing measures that better protect the most vulnerable users, balancing the safety of vehicle occupants with that of pedestrians.
