Even NHTSA while describing their recommendation for how to wear the seat belt while pregnant says: (NHTSA has since redesigned their site. Now we can find no mention at all about driving during pregnancy and seat belts.)

News Stories NPR – (5/12/14) While this article doesn’t mention the Tummy Shield, it does describe a Canadian study that shows women in the 2nd trimester are more likely to be involved in a motor vehicle crash. Tummy Shield can help protect mom and baby in the increased likelihood of a crash. USA Today – Nov. 27, 2009 – Researchers trying to protect pregnant drivers. Researchers and car manufacturers realize seat belts aren’t the optimal answer to safety for pregnant women and although it’s the best safety device they have, they could make it better.
