The Gardaí are currently clamping down on misbehaviour by all road users, including cyclists, so please inform yourself about the specific offences for which cyclists can be fined.
The full list of fixed charge offences for cyclists is outlined below. (Thread)
Lights: You need to have a working front light (white) and back light (red) during lighting-up hours, i.e. at night.
- You do not legally need lights on your bike during the daytime.
- "Hi-vis" clothing is not a legal requirement, day or night.
Lights, continued:
Having no front or back lights is a single offence. Beware of anyone attempting to charge you with two separate offences, i.e. One penalty for no front light, and a separate additional penalty for no back light.
