Ireland for Canadian Drivers — The Left-Side Switch & Narrow Lanes

The one thing that defines driving in Ireland for a Canadian isn’t the paperwork — it’s that Ireland drives on the left. You’ll sit on the right-hand side of the car, change gear with your left hand, and circle roundabouts clockwise, all the mirror image of home. This is the single biggest adjustment, and it doesn’t feel natural for the first hour. Pick up the car somewhere quiet, not at a busy airport exit, and spend that first hour deliberately talking yourself through every junction until “keep left” stops being a conscious decision.

The narrow lanes are where it gets real

Once the side switch clicks on a wide road, Ireland sets a second test: its rural lanes. Away from the motorways, roads narrow to barely one car’s width, walled in by stone or high hedges, with blind bends and no shoulder to bail onto. Many are posted at 80 km/h, a number that’s almost never actually safe — locals know the bends, you don’t. Slow right down, use the marked passing places, and accept that you’ll sometimes need to reverse to let an oncoming car or tractor through. Combined with sitting on the unfamiliar side of the car, judging your left-hand clearance is the skill that takes longest to learn — clipping the hedge is a rite of passage, clipping a stone wall costs you the rental excess.

Paperwork and the rules that differ

A Canadian licence is accepted, with an International Driving Permit recommended rather than required — it mainly smooths the rental desk, and you carry both with your passport. Confirm the detail on the Driving Permit Checker. Ireland’s alcohol limit is 0.05, stricter than the 0.08 in most provinces and just 0.02 for newer drivers, with checkpoints common. Motorways run to 120 km/h and are tolled in places — the M50 around Dublin uses barrier-free eFlow cameras, so you must pay online by 8pm the next day or face a penalty, a trap that catches plenty of visitors who never saw a toll booth.

Practical notes

Ireland mandates no specific equipment, though basic safety kit is sensible. Petrol is around $1.82/litre, and 112 (or 999) reaches all emergency services.
