Despite their significant contribution to air pollution and road accidents, vehicles older than 20 years old are still in circulation on Nepal's roads, largely due to a lack of actionon the part of the government and objection from transport entrepreneurs.These vehicles are widely recognized as a source of pollution and safety concerns for road use.

According to the Department of Transport Management (DoTM), there are a total of 5.85 million officially registered vehicles in Nepal, and registrations continue to increase annually.The counts include: 71,577 mini-buses and mini-trucks; 41,986 heavy machinery and trucks; 129,119 cars, jeeps, and vans; 91,483 pickups; 12,575 microbuses; 111,352 tempos; 4.744 million motorcycles; 190,064 tractors andpower tillers; 73,606 e-rickshaws; and 17,875 other vehicles—motorcycles being the majority.The Central Federation of Public Transport Nepal General Secretary Bharat Nepal has stated there are about 700,000 public transport vehicles, with about 140,000 vehicles over 20 years old.In 2070 BS the Council of Ministers had decided to phase out these vehicles.The term scrapping meant registering for des-inspection, selling at auction, and demolishing.In a full lack of communication, this policy below was never included in the Vehicle and Transport Act, rendering it moot and unenforceable to this very moment.
