  Delhi has the highest road density of 2103 km/100 km in India. It is connected to other parts of India by five National Highways: NH 1, NH 2, NH 8, NH 10 and NH 24. The Delhi–Mumbai and Delhi–Kolkata prongs of the Golden Quadrilateral start from the city. The majority of the city's roads which are 60 ft (18 m) wide or above are maintained by the Public Works Department (PWD) which is under the jurisdiction of the Government of Delhi while some are maintained by Delhi Development Authority and New Delhi Municipal Council which are under the jurisdiction of the Government of India. Roads and streets less than 60 ft (18 m) wide are maintained by the Municipal Corporation of Delhi. Roads and streets in unauthorised colonies are maintained by the local Member of the Legislative Assembly.
  
  Buses are the most popular means of road transport, catering to about 60% of Delhi's total demand. Delhi has one of India's largest bus transport systems. In 1998, the Supreme Court of India ruled that all public transport vehicles in Delhi must be fuelled by compressed natural gas (CNG) to tackle increasing vehicular pollution. The state-owned Delhi Transport Corporation (DTC) is a major bus service provider which operates the world's largest fleet of CNG-fuelled buses. In addition, cluster scheme buses are operated by Delhi Integrated Multi-Modal Transit System (DIMTS) with the participation of private concessionaires and DTC. In December 2017, the DTC and cluster buses carried over 4.19 million passengers per day. Kashmiri Gate ISBT, Anand Vihar ISBT and Sarai Kale Khan ISBT are the main bus terminals for outstation buses plying to neighbouring states. Delhi's rapid rate of economic development and population growth has resulted in an increasing demand for transport, creating excessive pressure on the city's transport infrastructure. To meet the transport demand, the State and Union government constructed a mass rapid transit system, including the Delhi Metro. Delhi Bus Rapid Transit System runs between Ambedkar Nagar and Delhi Gate. As per February 2024, Delhi has around 1,650 electric buses managed by the Delhi Transport Corporation, the highest in India and the third highest in the world after Shenzhen and Santiago.
  
  Personal vehicles, especially cars also form a major chunk of vehicles plying on Delhi roads. As of 2007, private vehicles account for 30% of the total demand for transport. Delhi has the highest number of registered cars compared to any other metropolitan city in India. Taxis, auto rickshaws, and cycle rickshaws also ply on Delhi roads in large numbers. As of 2008, the number of vehicles in the metropolitan region, Delhi NCR, was 11.2 million (11.2 million). In 2008, there were 85 cars in Delhi for every 1,000 of its residents. In 2017, the number of vehicles in Delhi city alone crossed the ten million mark with the transport department of Delhi Government putting the total number of registered vehicles at 10,567,712 until 25 May of the year.
