Labour councillors are calling for action as under five per cent of eligible young people in South Lanarkshire have been issued with their free bus pass.
Latest figures show that 4.8 per cent of eligible under-22s have received their free bus pass in the region, making it the lowest level of uptake on mainland Scotland.
Councillor Lynsey Hamilton, education spokeswoman for the Labour group, said: councils are responsible for "driving up" bus pass applications through co-ordinated action at school level.
