Carelessness of government traffic authorities, who certainly know of the problem but pretend to ignore it, or are afraid to fight the lobby of the trucking industry and trucks users.

In these cases, the difference between life and death, in these cases, is fully dependent on the performance of the guard. After all, guards must protect people in specific situations. If they don't, they are not guards, it's as simple as that. If it were known beforehand, they are accomplices to the crime. The world is a dangerous place to live in, not because of those who do evil, but because of those who watch and let it happen.
