Pregnancy causes diverse physiological changes including fatigue, nausea, distraction, and sleep disruption. These changes may contribute to driver error yet road safety is never discussed in prenatal care guidelines. We identified all women in Ontario who gave birth between 2006 and 2011 and evaluated intervals before, during, and after becoming pregnant (n = 507,262). We found that the second trimester of pregnancy led to a 42% increase in the risk of a serious motor vehicle crash. The increase was compensated in the third trimester, not associated with intentional injury, and accompanied by decreases in risky behaviours. The increased risk amounted to approximately 75 serious crashes each month in Ontario. We suggest that pregnancy is associated with an increased risk of serious motor vehicle crashes during the second trimester, which merits greater attention to good prenatal care.
