Laws on cycling in Ireland


In the interest of safety, it’s important that cyclists obey the rules of the road. As a cyclist, you are particularly vulnerable and face a real risk of serious injury or death if you are involved in an accident.

You are legally obliged to keep your bike in good working order. You must cycle with reasonable consideration, and be sober enough to control your bike.

If you are using a bike on a public road in Ireland it must be fitted with reflectors and lights to ensure that you are visible. All bikes on public roads must comply with the Road Traffic (Lighting of Vehicles) Regulations 1963 as amended. This law sets down the type of reflectors and lights that your bike must have and when you must use your bike lights. See our document on Bicycle lights for more information.

In addition to lights, your bike must also have:

  • A bell, which can be heard from a reasonable distance
  • Front and rear brakes (unless it has one fixed wheel, where it need only have one brake)
  • A rear reflector that can be seen from a reasonable distance


What other rules of the road apply to cyclists?

The Road Traffic Acts 1961-2018 set out the main provisions for motoring and legislate for bikes. There is also secondary legislation including the Road Traffic Acts and Road Traffic (Traffic and Parking) Regulations 1997-2019, which regulates the behaviour of motorists and cyclists.

When cycling you must:

  • Stop at traffic lights when required
  • Stop at pedestrian crossings and zebra crossings
  • Stop at cycle traffic lights when required
  • Stop at stop signs and yield right of way at yield signs
  • Avoid cycling on motorways

Section 100 of the Road Traffic Act 1961 makes it an offence to ride a bicycle while holding on to another moving vehicle (other than another bicycle which no one is riding).

Do I have to wear a cycling helmet or hi-visibility clothing?

You are not legally obliged to wear a helmet or hi-visibility clothing while cycling in Ireland but the Road Safety Authority of Ireland recommends cyclists wear both for safety.

Is it legal to cycle two abreast in Ireland?

Cyclists can cycle two abreast but under Article 47 of the Road Traffic (Traffic and Parking) 1997 Regulations (as substituted by the 2012 Regulations), you must not cycle more than two abreast, except when overtaking and it does not endanger or obstruct other traffic.

Can I overtake a vehicle on the inside?

A cyclist can overtake a vehicle on the left (or inside of the flow of traffic) if the vehicles to the right are stationary or moving more slowly than the cyclist.

However as a cyclist you cannot overtake on the inside if the vehicle you intend to overtake:

  • Is signalling an intention to turn to the left and will move to the left before you overtake it
  • Is stationary for the purpose of allowing a passenger to alight or board the vehicle
  • Is stationary for the purposes of loading or unloading

What are the rules about overtaking cyclists?

When overtaking, it is recommended that drivers should leave 1.5 metres between them and your bicycle in areas with speed limits above 50km/h. In areas with lower speed limits, drivers should allow one metre when overtaking.

Since 12 November 2019, it is a separate offence to overtake a cyclist dangerously. Drivers who overtake you dangerously while you are cycling are liable for a fixed charge of €120, and could have 3 penalty points added to their licence.

Am I legally obliged to use cycle lanes?

You must use a cycle lane in a pedestrianised area where an appropriate one is provided.

Where the cycle lane is a contra-flow cycle lane (allowing cyclists to go in the opposite direction to the traffic on a one-way street), you can only cycle in the contra-flow direction.

The regulation on cycle lanes is contained in Article 14 of the Road Traffic (Traffic and Parking) (Amendment) Regulations 1997, as amended.

What are fixed charge offences?

Since 2015 Gardaí have the power to stop cyclists and fine them for specific fixed charge cycling offences. Gardaí can fine cyclists for the following offences:

  • No front or rear light during lighting-up hours
  • Riding a bicycle without reasonable consideration
  • Failing to stop for a school warden sign
  • Failing to stop at traffic lights when the red lamp is lit
  • Failing to stop at cycle traffic lights when the red lamp is lit
  • Failing to stop at a stop line, barrier or half barrier at a railway level crossing, swing bridge or lifting bridge, when the red lamps are flashing
  • Cycling in a pedestrianised street or area

The fine for these offences is €40. If you receive a fixed charge notice, you have 28 days from the date of the issue of the fixed charge notice to pay the fine. If it is not paid within 28 days, the charge is increased by 50%. If it is not paid within 56 days then court proceedings are initiated (and payment will no longer be accepted).

If you misplace, lose or damage your fixed charge notice, you should contact the Garda Fixed Charge Processing Office (see ‘Where to apply’ below). A re-print of the notice will be sent to you by post. However, the time period allowed for payment is not extended by your request for a re-print.

If you pay the fixed charge notice within the legal time limits and court proceedings are not commenced, you will not have a criminal record in respect of the offence.

Further information on fixed charge notices is available on the Garda website. If you receive a fixed charge notice from An Garda Síochána, you can apply to have it cancelled due to exceptional circumstances. See the guide to cancellations of fixed charge notices.

Is it legal to cycle on a footpath?

You are not allowed to cycle on a footpath unless there is a designated cycle lane on the footpath or you are entering or exiting a property. Cycling on a footpath is not a specific fixed charge offence though. However, you could be fined for doing so if a garda deemed their cycling to be without ’reasonable consideration‘.

Similarly, you cannot cycle in a pedestrianized area at the designated times unless there is a cycle lane.

Is there a legal alcohol limit for cycling?

If a Garda suspects you are cycling under the influence of alcohol or drugs to the point that you do not have proper control of the bike, you can be arrested without a warrant. This is also the case if a Garda has reasonable grounds to suspect you are riding a stolen bike.

Securing your bike

What steps can I take to prevent my bike being stolen?

Gardaí advise people to spend a minimum of 10 per cent of the cost of their bike on two bike locks. They also recommend that you should:

  • Lock your bike tightly to an immovable object like a bike stand or lamppost
  • Keep the lock off the ground
  • Lock your bike in a well-lit public area
  • Photograph and keep a note of your bike’s serial number
  • Always report a bike theft to the Gardaí

According to Garda figures, the most common time for a bike to be stolen is during daylight between 8am and 5pm.
