During the times on the plate under the sign, a bus lane is for buses, bicycles, e-scooters, e-mopeds and working taxis. Cars — electric ones included — motorcycles, vans, hackneys and limousines must stay out, except to cross it to reach a property, or to move in where the line is broken just before a left turn. Contra-flow bus lanes and bus-only streets apply at all times. Undertaking in a bus lane is never allowed during its hours. Fines: €60 for driving in one, €80 for parking — no penalty points.
Can I use this bus lane?
Pick your vehicle and the type of lane to see what the rules allow.
No — not during the times on the plate. You may only cross it to get in or out of a property or driveway, or move in where the line is broken just before a left turn.
Fixed charge for driving in it: €60 (no penalty points). Parking in it: €80.The four types of bus lane — and who can use each
- Normal (with-flow) bus lane — runs the same way as the traffic beside it, usually on the left. It only applies during the times on its plate.
- Contra-flow bus lane — runs against the traffic, often on a one-way street. It applies at all times.
- Bus-only street — a whole street closed to other traffic, signed with a “no straight ahead” sign and a plate at each entrance. Others may enter only for access.
- Bus gate — a short stretch or junction where only listed vehicles may pass, such as Dublin’s quays. The plate lists who is exempt, so a bus gate can allow taxis.
| Vehicle | Normal bus lane (during its hours) | Contra-flow bus lane | Bus-only street | Dublin quays bus gates (7am–7pm) |
|---|---|---|---|---|
| Bus or coach (more than 8 passengers, for hire) | Yes | Yes | Yes | Yes |
| Bicycle, e-scooter or e-moped | Yes | Yes | Yes | Yes |
| Taxi, while working | Yes | No | Access only | Yes |
| Garda, ambulance, fire engine | Where safe | Where safe | Where safe | Yes |
| Car (incl. electric), van or lorry | No | No | Access only | No |
| Motorcycle | No | No | Access only | No |
| Hackney or limousine | No | No | Access only | No |
Since May 2024, cyclists, e-scooters and e-mopeds may use contra-flow bus lanes too — the current Rules of the Road (reflecting the law at 1 March 2025) still says buses only unless signs say otherwise. And taxis can’t use contra-flow lanes: their exemption only covers normal bus lanes.
Signs, times and white lines
The times are on the plate
Bus lane signs have an information plate below them with the times the lane operates — for example “07.00–10.00 Mon–Fri” — or “24-hour operation”. Outside those times, a normal bus lane is open to all traffic. The Rules of the Road says bus lanes normally operate from 7am to 7pm or during peak hours, but each lane is different, so always read the plate.
That’s a UK rule, not an Irish one. Irish signing guidance says every bus lane sign must carry a plate with either its times or “24-hour operation”. If you can’t see the plate, treat the lane as in operation.
The white lines
- Solid white line with “LÁNA BUS” painted on the road — this marks the bus lane. Don’t drive across it during its hours except to get in or out of a property.
- Broken white line — used at the start of a bus lane, across side roads, and before some junctions. Before a junction, it shows you may move into the bus lane to turn left.
- Red road surface — some bus lanes have one, but the colour itself has no legal meaning. It’s the sign, plate and white line that count.
11 real situations — and what to do
Each diagram shows the road from above, with traffic moving up the page. The bus lane is shaded red on the left; you are the green car. A green tick means the right move, a red cross the wrong one.
Turning left across a bus lane
1You want to turn left, and the bus lane line turns broken before the junction
- Signal left early and check your mirror and left blind spot for bikes.
- Move into the bus lane only where the line is broken, once it’s clear.
- Turn left at the junction.
- Don’t move over while the line is still solid.
- Don’t cut in front of a bus or bike already in the lane.
The rule: The Traffic Signs Manual uses a broken line before junctions to show drivers it’s permissible to enter the bus lane before turning left. Moving from one lane to another, you must give way to traffic already in it.
2You want to turn left, but the bus lane line stays solid right up to the junction
- Stay in your own lane and signal left.
- At the junction, check mirror and blind spot, then turn across the bus lane when it’s clear.
- Don’t drive along the bus lane to reach the junction.
The rule: During its hours, only buses, bikes, e-scooters and working taxis may enter a normal bus lane. Crossing it is allowed to reach a property — not to queue-jump to a junction.
3You’re about to turn left and a bus or bike is coming up the bus lane
- Wait. Let the bus or bike pass, then turn.
- Signal early, so a cyclist knows you’re turning — then still check your left blind spot.
- Never turn across the front of a bus or a cyclist.
The rule: Cyclists may legally pass slower traffic on the left, but not a vehicle that has signalled left and is about to turn. The Rules of the Road: don’t overtake a cyclist as you approach a junction if you are turning left.
Someone undertakes you in the bus lane
4You’re in a queue and a car speeds past on your left in the bus lane
- Stay in your lane and keep calm.
- Leave space ahead in case they force their way back in.
- If it was dangerous, report it through the Garda Traffic Watch online form — dashcam footage helps. In an emergency, call 999 or 112.
- Don’t swerve to block the bus lane, flash or follow them.
The rule: Driving in a bus lane during its hours is an offence: a €60 fixed charge. Enforcing it is the Gardaí’s job, not yours.
5You’re about to turn left and someone is undertaking in the bus lane
- Hold back and let them clear, even though they shouldn’t be there.
- Only turn once your mirror and blind spot are clear.
- Don’t start the turn to “make a point” — a collision is never worth it.
The rule: Before moving from your lane, you must give way to traffic already in the other lane, whether it should be there or not.
When passing on the left is legal
6The car ahead is waiting to turn right and blocking you
- You may pass it on the left in an ordinary traffic lane.
- If the space on the left is an operating bus lane, wait instead.
The rule: You may overtake on the left where the vehicle ahead has signalled to turn right and you are going straight on or turning left.
7Slow traffic in two ordinary lanes, and the right-hand lane is crawling
- It’s legal to move faster in the left lane than the queue on your right.
- This doesn’t extend to bus lanes during their hours.
The rule: In slow-moving traffic, you may pass on the left when vehicles in the lane on your right are moving more slowly.
8You’re driving outside the bus lane’s hours
- Read the plate under the bus lane sign. Outside the times shown, all traffic may use the lane.
- Normal lane rules then apply — including how and where you overtake.
- Don’t assume — some lanes run 24 hours, and the plate will say so.
The rule: A with-flow bus lane applies during the period of operation shown on the information plate. The Traffic Signs Manual says every bus lane sign must carry a plate with its times or “24-hour operation”.
Everyday situations
9You want to drop someone off
- Find a legal place to stop — a side road or a parking space.
- Don’t stop in a bus lane during its hours, even “just for a second”.
The rule: Only taxis may stop in an operating bus lane to pick up or set down passengers. Parking in a bus lane is an €80 fixed charge.
10You’re pulling out of a driveway across a bus lane
- Edge out and give way to buses, bikes and anything else in the bus lane, then cross to the traffic lane.
- Don’t drive along the bus lane after you cross it.
The rule: You may cross a bus lane solely to enter or leave a property beside it. Leaving a driveway, you must give way to traffic on the road.
11There’s a yellow box at the end of the bus lane
- Only enter it if your exit is clear and you can drive straight through.
- Don’t stop in the box — it’s there to let buses leave the bus lane.
The rule: Where a yellow box is placed at the end of a bus lane, only a vehicle exiting the bus lane may enter it unless you can clear it without stopping.
Dos and don’ts
Do
- Read the time plate under every bus lane sign.
- Signal left early and check your left blind spot before turning across a bus lane.
- Move into the bus lane only where the line is broken before your left turn.
- Give way to buses, bikes and e-scooters already in the lane.
- Cross a bus lane to get in or out of a driveway or property.
- Use the lane like any other outside its hours.
Don’t
- Undertake a queue in a bus lane during its hours.
- Drive along a bus lane to reach a junction early.
- Stop or drop someone off in an operating bus lane.
- Drive into a contra-flow bus lane or along a bus-only street.
- Follow a taxi into a bus lane — it has an exemption, you don’t.
- Stop in a yellow box at the end of a bus lane.
Fines and penalties
| Offence | Fixed charge (28 days) | Next 28 days | Penalty points |
|---|---|---|---|
| Driving in a bus lane, contra-flow bus lane, bus-only street or bus gate | €60 | €90 | None |
| Parking in a bus lane or on a bus-only street | €80 | €120 | None |
Neither offence carries penalty points — they’re not on the RSA’s penalty point list. If the fixed charge isn’t paid within 56 days, the case goes to the District Court, which sets the fine. Bus lane offences are separate from the offences that do carry points, such as dangerous overtaking or failing to yield — see our penalty points guide for those.
Who enforces bus lanes — and are cameras coming?
Today, Gardaí enforce bus lanes; traffic wardens can also ticket parking. Garda fines for unlawful driving or parking in bus lanes rose by over a quarter in 2024, according to Garda figures reported by the Irish Times:
A Garda spokeswoman linked the rise to more high-visibility patrols. In the first three months of 2025, Gardaí issued 2,663 bus lane fines, 2,143 of them in Dublin.
Ireland’s first National Safety Camera Strategy (April 2026) gives the National Transport Authority responsibility for traffic management cameras, including bus lanes, and recommends cameras on board buses as well as at fixed sites. New legislation is needed before they can issue fines, and no start date has been set. In an NTA trial in Cork in August 2024, AI cameras on two buses detected 60–70 incidents a day — about a quarter of them bus lane violations.
Dublin: the quays bus gates and College Green
Since 25 August 2024, Dublin City Council has run bus gates on the quays from 7am to 7pm, seven days a week. Only public transport, taxis, cyclists and emergency vehicles may pass — there are no permits or exemptions, and motorcycles are not allowed.
| Where | What changed, 7am–7pm |
|---|---|
| Bachelors Walk (north quays) | General traffic can’t continue straight on to Eden Quay; it must turn left at O’Connell Bridge. |
| Burgh Quay (south quays) | No straight on to Aston Quay for general traffic. |
| Westmoreland Street | The left turn onto Aston Quay is for public transport, taxis and cyclists only; the left onto Fleet Street is for deliveries and access. |
College Green has been closed to private cars at all times since 29 May 2023. Before that it was a 7am–7pm weekday bus gate, and the council counted nearly 10,000 cars a week driving through illegally during those hours.
Why drivers do it — and why it matters
The temptations are familiar:
- A long queue beside an empty-looking lane.
- Running late, and “it’s only a few hundred metres”.
- Not sure of the hours, or not seeing the plate.
- “Just a second” to drop someone off.
- Following a taxi in, without realising it has an exemption.
But a bus lane only works if it’s clear. Dublin Bus told an Oireachtas committee in 2022 that private vehicles travelling and parking in bus lanes reduce the efficiency of buses; that its peak network speed before Covid was about 14 km/h and needs to reach at least 18 km/h; and that all bus lanes should move to 24-hour operation to remove uncertainty for drivers. Dublin City Council found that at the Bachelors Walk / O’Connell Street junction, people in cars were just 2% of users but had at least half the road space — while bus users were 49%.
