Chile on an Irish Licence — The Side Switch & a 0.03 Limit

Chile is a superb self-drive country, but for an Irish visitor the very first thing to get right is the one no amount of itinerary planning prepares you for: you change sides of the road. Ireland drives on the left; Chile drives on the right, and that single switch is far more likely to catch you out than any speed limit or paperwork rule.

The danger window is your first day — pulling out of a fuel station onto the wrong side, taking a roundabout that now flows clockwise the other way, or the reflex glance in the wrong direction at a junction. Overtaking moves to the left, the gear stick is on your right, and your instincts will fight you for the first hour. Collect the car somewhere quiet rather than in central Santiago, be deliberate at every turn, and the reflex resets within a day or two.

The alcohol law is the second adjustment. Chile sets a 0.03 limit, below Ireland’s 0.05, and enforces it with routine weekend checkpoints and penalties that escalate quickly. There is no margin for a drink with lunch; treat it as zero before driving.

Paperwork is straightforward. Your Irish licence is accepted for tourists, and an International Driving Permit is recommended as a translation that smooths the rental desk and any roadside stop — carry it with your licence and passport, arranged in Ireland before you fly.

Once you are settled on the right, the driving is good. The Pan-American Highway (Ruta 5) runs the length of the country as mostly tolled motorway at up to 120 km/h, quiet outside the capital. But the northern leg crosses the Atacama, where fuel stations sit as much as 200 km apart, signal disappears, and the heat is severe — fill up in every town, carry water, and load offline maps. Town limits are 60 km/h, rural roads 100, and a 10 km/h overspeed costs roughly CLP 38,000-70,000 (≈ €35-65). Cars must carry a warning triangle and reflective vest, usually supplied with the rental.

Fuel runs about CLP 1.35/litre equivalent and the emergency number is 131 for ambulance, 133 for police. Read the full rules on our Chile driving guide, confirm your documents with the Driving Permit Checker, and price any fine with the Speeding Fine Calculator.
