In February 2025, Ireland’s default speed limit on rural local roads dropped from 80 km/h to 60 km/h, a change affecting roughly 82,000 kilometers of road, according to the Department of Transport. For visitors used to different road rules back home, details like this can catch you off guard mid-trip.
At Royal Historical Tours, we spend as much time behind the wheel of Ireland’s roads as we do planning around them, and we know exactly where first-time drivers tend to get caught out. Below, we cover driving on the left, rural roads, roundabouts, current speed limits, and route-finding, so you know what to expect before you turn the key.
Driving on the Left
If you’re used to driving on the right, this takes a short adjustment period.
Keep to the left lane on all roads, including motorways and rural routes.
Roundabouts move clockwise, and traffic already on the roundabout has the right of way.
Overtaking happens on the right-hand side of the vehicle in front, not the left.
Most visitors adjust within the first hour or two, particularly if the first stretch of driving is on a quieter road.
Understanding Rural Roads
Ireland’s rural road network looks different from what many international visitors expect.
Width: Many country roads are single-lane in practice, even without a center line, so oncoming traffic requires slowing down and sometimes pulling in.
Surface and signage: Surfaces vary and signage can be sparse on the smallest roads, particularly in the west.
Livestock and cyclists: Sheep, cattle, and cyclists can appear on rural roads with little warning, especially near farmland.
Hedgerows: Tall hedges on either side of narrow roads reduce visibility at bends, so a slower approach speed matters more than the posted limit.
Roundabouts, Explained
Roundabouts can feel unfamiliar at first but follow a consistent set of rules.
Yield to traffic already on the roundabout, which will be coming from your right.
Choose your lane based on your exit before entering, especially at larger, multi-lane roundabouts.
Signal left just before your exit, regardless of which lane you started in.
Smaller rural roundabouts may have no lane markings at all; slow down and follow the flow of traffic.
Current Speed Limits at a Glance
Motorways: 120 km/h
National roads and dual carriageways: 100 km/h
Regional roads: 80 km/h
Rural local roads: 60 km/h (reduced from 80 km/h in February 2025)
Towns and villages: 50 km/h, with some urban cores moving toward 30 km/h
All limits are posted in kilometers per hour, not miles, so recalibrating your instinct for what “60” or “100” feels like is worth doing early in the trip.
Should You Drive Yourself, or Let Someone Else Handle It?
Self-driving works well for travelers who enjoy flexibility and don’t mind the occasional narrow bend. For others, particularly those wanting to focus on sights like Dublin’s historic quarter, the Wicklow Mountains, or the Cliffs of Moher without watching the road, a private driver removes the guesswork entirely.
So, would you rather keep both hands on the wheel, or spend the whole ride looking out the window instead? Royal Historical Tours offers Dublin driving tours, Wicklow Mountains private tours, and Cliffs of Moher private chauffeur tours for travelers who’d prefer an experienced local driver over a rental car and a paper map.
Get in touch with us to arrange private tours to Wicklow or elsewhere around the country, and we’ll take care of the roads while you take in everything else.
