When your vehicle rapidly closes on the vehicle in front

When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle's line of travel

When climbing a steep hill causes an overhead billboard or other metal-

applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten it.
