Identities of the other victims could not be known immediately.
Senior Assistant Superintendent of Police Ariful Islam said some construction workers along with construction machine were going to Jhenaidah town at around 6:30pm while a truck hit their vehicle killing six on the spot and injuring four others.
The injured were taken to the Sadar Hospital, he said.
Meanwhile, road accidents continue to spike in Bangladesh, with the Road Safety Foundation (RSF), an advocacy group for less dangerous roads, reported 439 deaths from 417 accidents in November last year.
That meant fatalities were up nearly one-sixth or close to 16 percent from October, when 383 lives were lost in 314 accidents.
The number of accidents went up by nearly one-third, or 33 percent.
Nirapad Sarak Chai, another road safety advocacy group, in a report said that 5,227 people were killed in 4,702 road accidents in Bangladesh last year.
The World Bank has said Bangladesh needs to invest an estimated extra $7.8 billion over the next decade to halve its fatalities from road crashes.
The report pointed to the high death rate on Bangladesh’s roads as the consequence of a chronic lack of investment in systemic, targeted, and sustained road safety programmes.
