Pupils at 25 schools are being given the "Safemark", as part of the city's Respect for Transport campaign.

The scheme will see sixth-form pupils acting as good behaviour mentors to ensure pupils abide by agreed codes of conduct for travelling on school buses.

Nottingham City Transport says vandalism costs it £10,000 a month.

Promoting respect

At a ceremony at the Council House in Nottingham on Friday, the participating schools were officially given the "Safemark".

Nicola Tidy, from Nottingham City Transport, said: "It's about raising awareness of how to behave properly on a bus to make sure they are transported safely.

"It's also to raise awareness of other people on buses because quite a lot of children use normal service buses.
