Objective: The purpose of this study was to clarify the influence of automobile driving in the third trimester of pregnancy on fetal heart rate and uterine contraction. Methods: Twenty‐nine pregnant women with singleton pregnancies after 28 weeks of gestation were monitored using a portable cardiotocogram during driving, and the results obtained before and after driving were compared. Results: Baseline fetal heart rate and its variability, as well as periodic fetal heart rate patterns, showed no abnormal patterns during car driving. Automobile driving in late pregnancy was not a reinforcement factor for uterine activity. Maternal systolic and diastolic blood pressure and heart rate showed no specific characteristic or adverse change during driving. Conclusion: The results of this study suggest that automobile driving in the third trimester of pregnancy has no adverse influences on either pregnant women or fetuses.
