The 84-hour nonstop countrywide hartal, called by the BNP-led 18-party alliance demanding elections under a non-partisan government, began at 6am Sunday.
The shutdown will end at 6pm on Wednesday.
All types of vehicles engaged in providing medical services, ambulances, media vehicles, medicine shops and food shops will remain out of the purview of the hartal.
At least 15 vehicles were set to fire, around 100 others were vandalised, a score of crude bombs exploded and several people were injured in indiscriminate incidents of violence on Saturday, a day before the 84-hour long countrywide hartal.
The opposition alliance on Friday announced a 72-hour hartal. Later, it extended the hartal for another 12 hours, protesting the arrest of senior BNP leaders on Friday night
Hours after the 72-hour shutdown plan was made public on Friday, five leaders of the main opposition BNP were arrested.
Earlier, two 60-hour hartals claimed the lives of several people and injured hundreds of others in the nationwide violence which ensued.
