Effects of seat belts worn by pregnant drivers during low-impact collisions

Aim of this study was to understand the injury mechanisms of pregnant drivers and associated fetal outcomes. The study consisted of frontal and rear impact tests using a dummy representing the anthropometry of a pregnant woman were conducted.
Results of the study showed that in frontal impact tests without a seat belt, abdominal pressure peaked at the point where the dummy contacted the steering wheel. Rear impact tests without a seat belt showed that the dummy moved forward because of rebound and contacted the steering wheel, which was avoided when a seat belt was worn.
The study concludes that wearing a seat belt reduces abdominal pressure or prevents contact with the steering wheel during collisions.
