The First Bus group has warned vandals that they face having to pay for the damage they cause out of their own pockets.
Windows on a couple of the First vehicles were smashed
The company has successfully managed to bring an action against two Glasgow teenagers for smashing bus windows.
The pair were forced to pay between £300 and £350 each.
A court ruling now allows First to ask police for the names of vandals and the company has said it plans to pursue all offenders.
In 2002, two individuals were investigated by Strathclyde Police in relation to two separate incidents, during which First's buses had been vandalised.
In order to obtain compensation from those responsible for the damage, First initially obtained a court order requiring the chief constable of Strathclyde Police to release their identity and contact details.
The company then successfully raised two separate actions in Glasgow Sheriff Court against the two youths from the Priesthill and Castlemilk areas and they were ordered to compensate First for damage they had caused.
Eric Stewart, managing director of First, said "Safety of passengers and staff is of primary importance to First, and we continue to help provide educational and diversionary activities to tackle vandalism, particularly youth related vandalism, against buses.
"Regrettably there will always be a minority who still resort to this frightening and anti-social behaviour.
"These court rulings and co-operation from our colleagues at Strathclyde Police show that we have the ability to really hit back at bus vandals, by hitting their pocket, and making them pay back the cost of the damage, a debt that will stay with them until it has been fully recovered."
Chief Inspector Donald MacLeod, of Strathclyde Police, said: "All forms of vandalism in the community are unacceptable. Persons young or old require to take responsibility for their actions.
"The travelling public can rest assured that we will continue to work together with First Glasgow, Glasgow City Council and the wider community to prevent such incidents and where appropriate detect offenders."
First has approximately 8,000 windows in its 1,000 Glasgow area buses broken every year - an average of 23 per night.
