Ashok Leyland vehicles have built a reputation for reliability and ruggedness. The 5,00,000 vehicles we have put on the roads have considerably eased the additional pressure placed on road transportation in independent India. In the populous Indian metros, four out of the five State Transport Undertaking (STU) buses come from Ashok Leyland. Some of them like the double-decker and vestibule buses are unique models from Ashok Leyland, tailor-made for high-density routes. The blueprint prepared for the future reflected the global ambitions of the company, captured in four words: Global Standards, Global Markets. This was at a time when liberalisation and globalisation were not yet in the air. Ashok Leyland embarked on a major product and process upgradation to match world-class standards of technology. In the journey towards global standards of quality, Ashok Leyland reached a major milestone in 1993 when it became the first in India's automobile history to win the ISO 9002 certification. The more comprehensive ISO 9001 certification came in 1994, QS 9000 in 1998 and ISO 14001 certification for all vehicle manufacturing units in 2002. It has also become the first Indian auto company to receive the latest ISO/TS 16949 Corporate Certification (in July 2006) which is specific to the auto industry.
