Denmark on an Irish Licence — The Right-Hand Switch & Bridge Tolls

Paperwork-wise Denmark is easy for an Irish visitor: your EU licence is valid as it is, no IDP, no translation. The catch is on the road, and it’s the same one that catches every Irish and British driver heading to the Continent — Denmark drives on the right. That’s the single adjustment that matters, and the rest of the trip is one of the gentlest in Europe.

The danger with the side switch isn’t motorway cruising, where you just follow the flow. It’s the instinctive moments: pulling out of a petrol station, taking a roundabout the opposite way to home, a reflex glance over the wrong shoulder. Spend your first hour on quiet roads, not in central Copenhagen, and consciously place the car to the right at every junction until the habit flips. Within a day it stops feeling backwards.

Once you’re settled, Denmark looks after you. Motorways run to 130 km/h, towns 50, rural roads 80, on excellent surfaces with clear signage. The alcohol limit is 0.05 — the same as Ireland — but Danish fines scale with income, so a serious breach costs more than the flat figure suggests. Routine speeding is steadier: about DKK 1,000 (≈ EUR 135) for 10 over, which you can check on the speeding fine calculator. Cameras are widespread.

The cost that surprises first-timers is the bridges. Denmark’s islands are joined by tolled crossings — the Great Belt between Zealand and Funen at roughly DKK 250 (≈ EUR 34) each way, and the Øresund to Sweden at about DKK 510 (≈ EUR 68). These are the main routes, so plan for them. And as you adapt to the right, remember the Danish habit that doesn’t exist on Irish roads in the same way: dense cycle lanes with priority — always check your inside before turning right.

Only a warning triangle is required in the car, fuel is near $2.05/litre, and the emergency number is 112. The full local rules are on our Denmark driving guide.
