No – the Trier Semester Ticket is only valid for students enrolled at one of the universities in Trier.
Exeption:
You are enrolled at one of the partner universities participating in the University Network South West (Kaiserslautern, Koblenz-Landau, Saarland, no university of applied sciences). In order to take advantage of additional study opportunities you can enrol at the partner university without paying the social contribution for a second time. Only upon request (be attentive filling out the enrolling-form) students from partner universities can buy and use the Trier Semester Ticket.
