Germany has introduced an unlimited public transport pass that costs less than $15 a month.
Costing just €9, the pass can be used on local busses, trams, U-Bahn and S-Bahn metro trains. Passholders will also be able to ride on local and regional trains.
The initiative was introduced in response to increased living costs, including hikes in petrol prices, partly caused by the Russian Ukraine conflict.
It will cost the government €2.5 billion (NZ$4.1 billion).
A three-month trial will start June 1 however federal Transport Minister Volker Wissing said it was "already a success", according to The Local.
