Costa Rica for Swiss Drivers — Forget Swiss Tarmac, Meet One-Lane Bridges

A Swiss driver arrives in Costa Rica with the easy things handled — you stay on the right, and the alcohol limit is the familiar 0.05. What no Swiss road prepares you for is the surface. Costa Rica is mountainous like home, but the resemblance ends at the geography.

Switzerland sets the global standard for tarmac and tunnel engineering. Costa Rica does not pretend to. Outside the Ruta 1 corridor, the country is narrow mountain road, regularly potholed, with single-lane bridges where a small ceda el paso sign tells you who waits. The wet season from May to November softens unpaved sections and lifts rivers, so a 4x4 is the realistic rental for anything past the main towns. Town limits sit at 40 km/h, rural roads at 60, and the few motorway stretches at 100 — and the road conditions, not the signs, set your real pace.

Documents are straightforward. Your Swiss licence needs no IDP for a tourist visit; carry it with your passport and you are legal. The Driving Permit Checker confirms it. Because the 0.05 alcohol limit matches home, there is nothing to relearn there — but police checks are routine and drink-driving penalties are heavy, so the habit of zero before driving travels well.

Speed is enforced by fixed cameras and roadside police on the main roads. A serious overspeed of about 20 km/h over costs roughly CRC 53,000 (around EUR 95), which you can model on the Speeding Fine Calculator. Realistically, though, the terrain disciplines your speed long before a camera does — blind bends and abrupt potholes do the work.

Fuel is about $1.28/litre, and 911 answers all emergencies. Download offline maps, because the valleys and coast both lose signal, and see the full picture in our Costa Rica driving guide.
