(1) To evaluate maternal and fetal outcome after motor-vehicle injury during pregnancy. (2) To determine if there was prenatal care provider counseling for seat belt use.

Retrospective chart analysis of materno-fetal outcome following motor vehicle injury in 728 pregnant women between 2009 and 2012. Women attending antenatal clinics over these years were asked if they were counseled regarding correct seat belt use by prenatal health care providers during their antenatal visits.

There were 100 (13.7%) maternal and 78 (10.7%) fetal deaths. 91 (12.5%) perimortem cesarean deliveries were performed and 74 (81%) fetus survived, as did 31 women. Prenatal care provider counseling for seat belt use occurred in 44.8% of prenatal visit. Only 125 (21%) were using seat belt during the accident.

Important causes of adverse pregnancy outcome were: abruptio placenta, preterm labor and uterine rupture. There were 100 maternal and 78 fetal deaths with 97 preterm births. Counseling occurred in 44.8% of women. Those using seat belts during the accidents sustained minor injuries.
