Accidents happen anywhere

Accidents can surely happen anywhere. One disturbing accident that happened in December here is when a tanker with fuel that was climbing a bridge suddenly didn't make it up the bridge and started rolling downwards. It turned upside down and burst into flames. The flames spread to a car workshop nearby and burned several cars. Some people say up to 20 cars. Nobody knows when an accident can happen.

Was there a driver in the vehicle?

The driver or owner of that truck should have been more aware. Usually with that kind of trucks we don't just depend on the hand break. To make sure it doesn't move at all, shift it to the first gear..

That is correct. I just witnessed one the other day when a motorcycle lost its balance and the driver with his backrider had a heavy fall.

In the roads near us there are accidents everyday. Most of the times young people die.
