Early this week a bus was swept away by floods in the central province of Ha Tinh, leaving 19 people missing.
While the accident was heartbreaking, some said philosophically that it was unfortunate, adding the rider that these things can't be helped.
Was it just bad luck, though? As one of the passengers on a bus running through flooded areas in Quang Binh Province, which was also hit by the floods, I don't think bad luck is explanation enough.
It happened because many of us are ignorant about threats to other people's and even our own lives.
In fact, most drivers don't bother to stop when faced with flooded areas. Maybe it's because they are too confident in their driving skills, or because they want to avoid fines by reaching destinations on time.
Whatever the reason, drivers, especially bus drivers, need to understand that they cannot compromise their passengers' safety under any circumstances. However this understanding seems absent among many drivers who go through flooded areas without thinking about the risks that lie under the water's surface.
Sometimes the drivers are also encouraged by the absence of warnings or directions from related agencies in the affected areas, or by the agencies' lack of determination in stopping them. It misleads them into thinking that the areas aren't that dangerous.
Worse still, in many cases, passengers themselves urge drivers not to stop and proceed to go through flooded areas despite the latter's warnings.
Even now I can't understand if the accident happened because the passengers were too brave, or because they weren't fully aware of the risks.
In such cases, ignorance is not bliss. It leads to disaster and tragedy.
