Accident do happen. But when they do, it's because somebody made a mistake. Somebody was in a hurry, or got distracted, or got reckless and irresponsible. It's always the result of a mistake.
Why accident happens?
Accidents happen because people did not do his best to prevent it. Most people believe that accidents do happen no matter what we do prevent it. This is the reason why people are not doing their best to avoid and prevent accidents from happening.
Some people also tend to be complacent and over confident for a lot of reasons. “I have been doing this many times and I never made any mistakes why worry now.”
Most injuries are preventable. People tend to blame their injuries on "accidents." However, when you examine the causes of most accidents, you’ll find that the accidents are actually the result of predictable and preventable occurrences. Suppose you know you’re driving with bald tires. If one of them blows out, causing you to lose control of the car and crash, this is not an accident. It’s a predictable and preventable event.
To prevent injuries, people must accept responsibility for their actions and must take obvious steps to eliminate safety hazards.
