The 3.0 m width accommodates a standard car (~2.0 m) plus clearance for door opening and maneuvering without scraping walls. For two-way traffic, a 5.5-6.0 m width is necessary to allow two vehicles to pass safely, a standard derived from parking aisle design in the NBC.
In group housing and apartment complexes, internal roads are typically 6.0 m wide to accommodate two-way traffic and serve as mandatory fire tender access paths. For individual low-rise plots, where fire tender access is provided from the main road, a 3.0 m driveway is a common minimum.
