Xplore Dundee is reminding youngsters to carry the correct ID when using its buses.
From April 1 those aged 16-18 must show their YoungScot card with their bus ticket.
Xplore Dundee was previously able to accept any form of photographic ID from its young customers, but new procedures introduced by Transport Scotland now mean only the YoungScot card is valid.
Anyone needing to apply for a YoungScot card can do so by visiting Xplore’s travel centre or visiting the YoungScot website young.scot/the-young-scot-card.
Xplore also wants to remind students that they must show a valid college or university matriculation card with the expiry date clearly displayed.
For those youngsters wishing to purchase an mTicket, they will also be required to show the correct identification upon boarding the bus, even if they have already purchased their ticket.
Xplore had previously only asked for ID at the point of purchase, in order to ensure the correct fare has been paid.
In January 2016, the bus company extended its discounted travel to cover young people until their 19th birthday.
Currently the operator is the only Scottish city operator to offer child and young person fares to age 18.
Signs are displayed on buses warning young people of the new rules.
