That is wonderful that the child survived...unbelievable.. that semi just cleared the child.
Considering the road'* weather conditions...
IF the truck where recording was made was doing 55-60 mph....
How fast was parents SUV travelling when it passed the truck then impacted the other rig?
Stuipid, to even attempt it considering the narrow margin of error/conditions.
Probably all season worn radials to boot.
Parents= Complete Failures.
