asked Her Majesty's Government:

Whether it is still an offence in Northern Ireland to ride a bicycle on a footpath, to go through traffic lights at red on a bicycle or to have no lights of any kind on a bicycle after dark. [HL1239]

I can confirm that each of these actions is a criminal offence under road traffic legislation.

Riding on the footpath is an offence under Article 3 of the Road Traffic Regulation (Northern Ireland) Order 1997; riding through a red light is caught by Article 50 of the Road Traffic (Northern Ireland) Order 1995; and the Road Vehicles Lighting Regulations (Northern Ireland) 2000 require bicycles to be lit after dark.
