Why Women Are More Likely to Suffer Serious Injuries in Car Accidents: A Study
Despite ongoing improvements in vehicle safety systems, women face a 60% higher risk of injury in car accidents compared to men. Austrian researchers conducted a study analyzing accident data from 2012 to 2024 to uncover the reasons behind this disparity.
In 80% of cases, women are passengers and sustain more severe injuries than men. However, the issue is not solely related to their position in the vehicle.
It was believed that modern seat belts and airbags protect everyone equally, but statistics reveal that even in the same car, women are significantly more likely to suffer serious injuries. Researchers aimed to determine whether this is linked to driver behavior, accident types, or safety system features.
Different Outcomes from the Same Accident
Researchers from the Graz University of Technology focused on accidents involving passenger cars, comparing injury severity, the position of individuals in the cabin, and accident circumstances. One key finding was that even at low speeds, women sustain more serious injuries than men.
To analyze this, computer simulations of six real frontal collisions were conducted, where both a man and a woman were present in the vehicles. In every case, the woman sustained more severe injuries.

Virtual crash tests revealed that the passenger's seating position often becomes a key risk factor. Women frequently adopt uncomfortable postures, increasing the likelihood of injury. Since women are statistically more likely to be passengers, they face these risks more often.

Even when women are driving or seated correctly, they still tend to suffer more serious injuries, indicating deeper issues with safety systems.
Women Are Not Just Smaller Men
The analysis revealed that the primary issue lies within safety systems. Crash tests have traditionally used dummies designed around male body types, neglecting the anatomical differences of women.

On average, women have lower body mass, a different center of gravity, narrower shoulders, different pelvic shapes, and less muscle mass in the neck and upper body. During a collision, all these factors influence how the body moves forward, how the seatbelt fits, and the stress experienced by the spine and internal organs.
The report also notes that in some cases, the force of the seatbelt was too great for the delicate female skeleton, potentially leading to injuries to the chest, spine, and shoulder girdle.
The authors of the study believe that the solution lies in "smart" systems capable of adjusting the force of deployment based on the size, gender, and position of individuals in the cabin. Additionally, new testing standards are needed, including more realistic female dummies and testing various seating positions.
