Un opérateur de réseaux fait sa maintenance tranquillou sur une route verglacée tandis que les automobiles vont à vau-l'eau. le gars qui filme a beau s'époumoner à lui expliquer que c'est une situation accidentogène, il s'en moque éperdument. Pendant ce temps-là, un autre accident va survenir.
They didn't have any warning signs indicating work or a closed lane ahead, which are to be 500 feet or more before the taper.
They didn't have anyone directing the lane changes, forcing cars to merge into oncoming traffic on their own.
They did not use a buffer space (the space between the work zone and the taper zone where traffic merges). According to u/kcorkery45, buffer zones are to be a minimum of 305 feet.
Their taper zone was far too small (minimum requirement is 50 feet), even if you ignore the weather conditions.
All distances listed are a minimum under safe driving conditions and good line of sight for drivers, and these distances should be increased as needed due to speed, weather, and condition/geometry of the road.
