Can I board through the front door to buy a ticket?
Boarding via the front door is permitted only if you use t:card value/autotravel value, need to start a periodic ticket or pay with credit card on region bus. On metrobuses all doors are open. If you travel from a metro station, validate your t:card before boarding.
