At least 418 people were killed and 497 others injured in road accidents in December last year across the country.
During the period, a total of 383 road accidents took place.
Among the deceased, 63 were women and 49 children, according to a report by Road Safety Foundation (RSF).
Around 178 people died in 167 motorcycle crashes in the last month which is 42.58 per cent of the total number of deaths, said the report, released on Saturday.
The highest number of accidents took place in the Dhaka division with the highest number of deaths. Some 113 people died in 102 accidents in Dhaka division, the report revealed.

Besides, three people died and eight went missing in three waterway accidents in December.
Further, 49 people were killed after a fire broke out in the Abhijan-10 launch on the Sugandha River, where 34 were injured and an unidentified number of people remained missing.
Around 22 were killed and nine wounded by 13 railway accidents.
The RSF prepared the report based on news items of seven national dailies, five online news portals and visual media.
Unfit vehicles, rash driving, lack of skill, mental and physical sickness, inadequate benefits for drivers, slow movement of vehicles on the highways, reckless bike ride by youths, lack of awareness about traffic laws were responsible for the accidents, the RSF observed.
The organisation suggested increasing skilled drivers, strengthening the capability of Bangladesh Road Transport Authority (BRTA) and enforcing of the Road Transport Act-2018 without any disruption to check road accidents.
