All 16 to 18-year-olds in Wales will be able to save a third off the price of adult bus fares from 1st September, Welsh ministers have announced.
The Welsh Young Persons Discounted Travel Scheme applies to local journeys and longer distance TrawsCymru routes.
The project, costing £15m between now and April 2017, is part of a Labour-Liberal Democrat deal to pass the Welsh government's budget.
The first minister launched the scheme at an event in Corwen, Denbighshire.
Carwyn Jones encouraged all 110,000 16 to 18-year-olds in Wales to register their interest at Gov.wales/mytravelpass.
