A journey can begin on a ring road, long before the cliffs and winding Atlantic lanes. Leaving Dublin, with left-hand driving still unfamiliar, purple signs are a reminder that a road trip also requires planning for its less romantic details. For those exploring Ireland by car in 2027, tolls will be among the costs to reassess: Transport Infrastructure Ireland, the body responsible for the national roads, has confirmed further increases. They remain modest for cars, but their application varies according to the route and payment method.
An increase announced for the start of 2027
The M3 is the exception for cars
In its statement of 30 October 2026, TII confirmed that the new rates will take effect on 1 January 2027. The adjustment is based on the indexation mechanism set out in the toll regulations, using a reference inflation rate of 3.6%.
It would, however, be misleading to conclude that every journey will increase by the same amount everywhere. Cars are exempt from the increase on the M3 between Clonee and Kells. On the other private concessions, their toll rises by ten cents. The M50 and the Dublin Port Tunnel are governed by separate provisions, detailed in the practical information box below.
On the M50, the absence of a barrier can make payment easy to forget
Only one section of the ring road is tolled
For visitors, the main pitfall is not necessarily the new charge, but how the toll operates. On the M50, cameras record number plates between junctions 6 and 7, with no need to stop at a booth. Using another section of this motorway does not therefore automatically trigger this toll.
This distinction is worth bearing in mind when planning journeys around Dublin. It prevents travellers from assuming that the entire ring road is tolled and makes it easier to understand the route actually taken, rather than looking afterwards for a barrier that was never there.
Rental car: the question to ask before setting off
Establish who pays the tolls
eFlow asks rental customers to check their agreement: some companies charge for tolls, while others leave drivers to pay them. Before leaving the desk, ask for the procedure relating to the M50 and whether any administration fees apply. A system covering this motorway does not necessarily mean that the other tolls on your trip will be included.
If payment is your responsibility, keep the vehicle registration number and proof of payment. The official deadline is given in the practical information box. This small check matters more than an impromptu last-minute detour, particularly when you need to return the vehicle before a flight.
The Port Tunnel: a highly targeted increase
Direction of travel changes everything
At the Dublin Port Tunnel, the announced increase applies only to journeys towards Dublin city centre during the weekday morning peak. All other charges remain unchanged. The tunnel must therefore be distinguished from the M50: they are two different tolls, and their terms do not overlap.
When planning an itinerary, compare the proposed route, the time available and traffic conditions. Avoiding tolls at all costs is not necessarily a saving if it means taking a significantly longer route. The key is simply to know the costs before setting off, then enjoy the journey without allowing a road payment formality to become an unpleasant surprise.
Practical points for your departure
Official rates to check again before your trip
The announced amounts apply to the roads in the Republic of Ireland covered by TII. They do not represent a general change to road rules across the whole island. If your itinerary also crosses Northern Ireland, bear this difference in scope in mind.
Information checked on 2 November 2026 with TII and eFlow. Before you travel, consult the official rate for your vehicle and your rental company’s terms: a private car and a commercial vehicle do not necessarily fall into the same category.
