There haven’t been any prosecutions over the past five years for defacing road signs.
It’s a common sight in Mid-Ulster where the ‘London’ in Londonderry is often spray painted over (pictured).
Incidents have occurred on the Moneymore dual carriageway and near Castledawson.
The information came to light in response to a question from DUP Assembly Member Adrian McQuillan.
Infrastructure Minister Chris Hazzard confirmed it is an offence to damage a sign.
He says the courts will require clear evidence before an effective prosecution can be brought.
