New fines come into effect today for cyclists who carry out seven offences.
The new system is designed to promote safe cycling.
Gardaí can issue cyclists with €40 fines for the offences which include cycling on a pedestrian street, breaking a red light and failing to stop for a school warden.
They can also be applied to cyclists who pass a barrier or bridge at a level crossing when the red lamps are flashing.
Penalties will also be applied for cycling without reasonable consideration and not having front or rear lamps lit on their bikes when its dark.
The new fines are designed to make cycling safer and Transport Minister Paschal Donohoe said he will further examine the legislation in force in relation to cyclists, as well as looking at further pro-cycling measures.
