I feel so horrible for the children and husband of the woman driving her Yukon who died... how horrible... True, the bright side is that her baby was safely delivered (but it is said he is in critical condition) and that her children were fine (I'm hoping that by "seatbelt" it means that they were in booster seats or carseats, not JUST seatbelts).
It doesn't say what happened to her husband, the driver, but I hope that he survived so that his children won't have lost two parents.
The Senator was apparently at fault as it was her vehicle that crossed the center... and because of her irresponsibility in her own car (having the kids and her son not wearing ANYTHING to protect them) as well as in general, this poor woman isn't alive to hold her baby or comfort her children.
A CRV is newer than a Yukon, I think, so that might have been why it faired better than the Yukon...
and yes, a seatbelt works very well when you are pregnant... I rearended another car when they stopped without warning just after a left turning light when I was 6mo pregnant with Damian... I was wearing my seatbelt properly and the airbag also helped keep me in position... except for some knee soreness and marks on my hands from them being thrown off the steering wheel, I was fine.... the doctor was actually surprised not to have me having any contractions... swore the airbag (they were still newer at the time to being mandatory and all) working with the seatbelt to prevent me moving as much as without the airbag and to help cushion things had to have been why.
In this case, I'm suspecting she hit the passenger side of that vehicle... or that hitting it threw the passenger side against somewhere hard.

I found this info - the Yukon ROLLED onto the driver side (you have to read quite a ways down to find that it landed on it's driver's side)
Oh... and the reason they were unbuckled... because their father had climbed back to put them in pajamas... GRRR... and they are implying that this distracted the senator and caused the crash... so much stupidity
