In Pakistan, close to 9,000 road accidents are reported to the police every year since 2011, killing over 4,500 people on average, according to the Pakistan Bureau of Statistics (PBS).

On Tuesday, over 55 people were killed in Khairpur, Sindh, in what was the country’s worst traffic accident in a year after a passenger bus and truck collided. This terrible tragedy did not occur in a void, or without predictors.

Pakistan has a poor record of fatal traffic accidents due to bad roads, badly maintained vehicles and reckless driving that remains unchecked by authorities.

To quantify the grave problem that persists, Dawn.com has visualised Pakistan's traffic accidents, built from data available from the PBS.

The data shows a downwards trend in accidents, deaths and injuries in general since 2004, although total numbers remain high.
