Transport chiefs in Nottingham are hoping a new award system will encourage school children to use public transport more responsibly. 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.
"And also to emphasise the driver is there doing them a service and he needs to be treated with respect."
