Always, before the car goes into gear, everyone in the entire car has to have on a seatbelt (From a purely selfish angle, I don't want to die or have someone else in my car die because you were unbuckled in my backseat and bashed me when you went sailing). Shoot, 5 miles an hour and no seatbelt can knock your teeth out on the dash! No thanks.
Two of our best friends were T-boned a few years ago in their minivan (someone ran a red light) and their van flipped 3 times. The witnesses said they were sure they were all dead. They all had on their seatbelts/carseat seatbelts. The 3 kids were fine, and the only serious injury was the DH, who hit his head on the windshield- he's fine now
. And the new van has airbags
. And just something to think about- if you are planning on your airbags protecting you, it won't do you a lick of good if you miss them!
Oh, and we also have a cutting tool and a tool to shatter the window in case of emergency.
