PHILADELPHIA (CBS) — According to a study out of Canada, women who are pregnant are at greater risk of having automobile accidents.

The study was done over five years, and it measured the driving habits of 500,000 women who were pregnant. It followed them before and after pregnancy, and it found that women were 42-percent more likely to be in a car accident when they’re pregnant, with the greatest risk during the second trimester.

The authors of the study say that fatigue and sleep deprivation could possibly contribute to the fact that pregnant drivers may not be as alert.
