Legally speaking yes but being legally right doesn't give you much comfort when you are dead. As has been said, there isn't enough info to determine what the woman knew or didn't and what she did or didn't do about it. I know that if it was my kid and I knew the truck was turning, I'd be making sure my kid was out of the way. I've seen far to many p*ss poor truck drivers in my day.
Exactly. You never know what last minute crap is going to happen, best thing is to pay attention and stay away from the road if a vehicle that size is making a tight turn as the back end of the trailer often wind up on the sidewalk. I've seen people do it, I've been in the vehicle when my ex-husband has done it - I would bet it happens quite regularly.
