"The culture of impunity would end if all the perpetrators were treated the same way," he said.

Jyotirmoy Barua, a Supreme Court lawyer working human rights issue, said families of many road accident victims did not file cases thinking that would bring little results.

"They know the legal fight would be time consuming … also in most cases, the accused belong to powerful [transport] associations," he told The Daily Star

Victims getting justice is very rare, said Jyotirmoy, also a vice chairman of Road Safety Foundation, adding that the government must act fast to prevent further loss of lives on road.
