From Swiss Roads to Ruta 40 in 2026: Permit, Alcohol Rules

Swiss drivers are trained by terrain — precise, patient, used to tight passes, tunnels and exact limits. Argentina keeps the rules familiar but throws away the tightness, and that is the adjustment worth preparing for.

Can a Swiss licence holder drive in Argentina? Yes, with an International Driving Permit. The Swiss licence is not accepted on its own. Argentina requires the IDP carried beside it, and a rental firm can decline the keys without one. Arrange the permit through the TCS before departure — it cannot be obtained in Argentina. Carry the IDP, your Swiss licence and your passport as a set.

The legal side will feel reassuringly close to home. Argentina drives on the right, as Switzerland does, so there is no side to relearn. Alcohol is different: Law 27.714 (May 2023) set the limit at zero, against 0.5 per mille in Switzerland. The one figure that rises is the motorway ceiling: Argentina permits 130 km/h against the Swiss 120, on roads that are far less engineered. Argentine provinces set their own penalties, so a fine for breaking either rule is neither fixed nor predictable.

The real shift is scale and surface. Switzerland packs its driving into a small, immaculately maintained network; Argentina spreads it across enormous, often single-carriageway distances. Buenos Aires is dense, quick and assertive — a long way from orderly Swiss city traffic — and demands you commit decisively at junctions. Beyond it, the long-distance roads are good but vast, with large gaps between fuel and services, and Patagonia in the far south is genuinely remote: plan your range, carry water, and do not assume the next town has a pump. Town limits drop to a strict 40 km/h and are enforced near cities.

A modest speeding fine runs around ARS 10,000–30,000 (about €10–30), varying by province. Glance at the pump board before filling; the emergency number is 911.
