Many precautions are taken in America to ensure that children getting off of buses are safe, but that is not the case everywhere.
Dashcam video from Norway shows kids coming off of a bus and then crossing the street behind it. The bus pulls away and a truck coming from the other direction doesn't see the children until the last minute.
The trucker slams on the brakes and by some miracle is able to stop his rig just short of striking one of the kids. Thankfully, aside from being shaken up, no one was hurt in the incident.
