Don’t enter a yellow box — even partly — unless you can clear it without stopping. That applies whatever the traffic lights show. The one exception: you may enter it to turn right and wait there for a gap in oncoming traffic, as long as you don’t block traffic that has the right of way. Breaking the rule is a €60 fixed charge with no penalty points.
The rule, word for word
Article 29 of the Road Traffic (Traffic and Parking) Regulations 1997 says a driver:
“shall not enter, either partly or wholly, the cross-hatched area unless the vehicle can clear the area without stopping.”
- Where: any yellow box on a public road or at a junction — including junctions with the Luas — with or without traffic lights.
- Traffic lights don’t change it: the rule applies “notwithstanding any indication to the contrary” given by the lights.
- The exception: it “does not apply where the driver of a vehicle intending to make a right hand turn at a junction enters the cross-hatched area for that purpose.”
- Emergency vehicles — Garda, ambulance and fire brigade on duty — are exempt from the traffic regulations where that doesn’t endanger other road users.
The marking itself — a yellow border with yellow diagonal lines — is set out in the Road Traffic Signs Regulations. The Traffic Signs Manual says boxes should be used only where other solutions won’t work, and can be placed at junctions (including roundabouts), Luas crossings, level crossings, the end of bus lanes, and outside Garda, fire and ambulance stations and hospitals.
What to do: 7 situations
Each diagram shows a crossroads from above, with you (green) approaching from the bottom. A green tick is the right move, a red cross the wrong one.
1Your exit is clear
- Drive straight through the box without stopping.
The rule: You may enter a yellow box only if you can clear it without stopping (Article 29(1)).
2Traffic is queued beyond the box
- Stop at the edge of the box and wait until there is room for your whole car on the far side.
- Don’t creep into the box hoping the queue will move.
The rule: If you can’t clear the box without stopping, you must not enter it — even partly.
3The light is green but the exit is blocked
- Wait behind the box even though your light is green.
- Don’t enter on green and sit in the box when the lights change.
The rule: Article 29 applies “notwithstanding any indication to the contrary” given by traffic lights. A green light never lets you wait in the box.
4You’re turning right and waiting for oncoming traffic
- You may enter the box and wait there for a gap in the oncoming traffic.
- Watch for cyclists coming through alongside the oncoming traffic.
- Don’t block traffic that has the right of way while you wait.
The rule: The box rule doesn’t apply to a driver who enters it to make a right turn (Article 29(2)). The Rules of the Road adds: don’t enter if you would block other traffic that has the right of way.
5You’re turning right but the road you’re turning into is blocked
- Wait at the edge of the box until the road you are turning into has room.
- Don’t pull into the box and sit across the junction, blocking traffic that has the right of way.
The rule: Strictly, the right-turn exception in Article 29(2) has no “exit must be clear” condition. But the Rules of the Road says not to enter if it would block other traffic with the right of way — and a car stranded mid-junction does exactly that.
6There’s a yellow box at the end of a bus lane
- Only enter it if you can drive straight through without stopping — it’s there to let buses out of the bus lane.
- Don’t stop in it, even to turn right.
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 (Article 29(3)). The right-turn exception doesn’t apply here.
7Traffic stops after you’ve entered with a clear exit
- Leave as soon as you can, without forcing your way out.
- Next time, wait until there is room for your whole car — plus a little more — beyond the box.
- Don’t reverse back out of the box.
The rule: The rule is about entering. The regulations include a general exception where compliance is “not possible as a result of an obstruction to traffic” — but whether that applies is for the Gardaí or a court, so don’t rely on it.
Bus lanes, Luas lines and level crossings
- End of a bus lane: a box in the traffic lane beside the end of a bus lane keeps a gap for buses to merge. Only vehicles leaving the bus lane may stop in it. More in our bus lanes guide.
- Luas crossings: the same Article 29 rule applies at junctions with the Luas, and the box may follow the tram’s path. In the Dáil in May 2026, a TD said the Luas Green Line was being delayed crossing the quays because of drivers remaining in yellow boxes.
- Railway level crossings: these have their own yellow box rule, with no right-turn exception. Breaking the rules at a level crossing is a different offence: €80 and 2 penalty points (5 on conviction).
- “KEEP CLEAR”: the white KEEP CLEAR marking at some entrances is not a yellow box. The Traffic Signs Manual classes it as non-regulatory — leave the gap as a courtesy.
Myths vs the law
The fine
| Offence | Fixed charge (28 days) | Next 28 days | Penalty points |
|---|---|---|---|
| Entering a yellow box other than in line with the rules | €60 | €90 | None |
| Railway level crossing rules (for comparison) | €80 | €120 | 2 (5 on conviction) |
If a yellow box fixed charge isn’t paid within 56 days, the case goes to the District Court, which sets the fine. Some websites quote €80 or €40 — the current amount, in S.I. No. 227/2024, is €60. See our penalty points guide for the offences that do carry points.
Enforcement and cameras
Today, yellow boxes are enforced by Gardaí. We could find no published figures for how many yellow box fines are issued each year.
Ireland’s first National Safety Camera Strategy (April 2026) lists yellow boxes at junctions among the traffic management offences to be enforced by camera, with the National Transport Authority responsible. The first phase focuses on speed, red-light and bus lane cameras, and new legislation is needed before anyone other than the Gardaí can issue these fines.
