Mexico on an Irish Licence — Yes, but You Switch to the Right
Ireland
Mexico
Yes. Bring your full Irish licence, as the Department of Foreign Affairs advises; Mexico is outside the 1949 convention, so an IDP is optional. Switch to the right and cross topes at 5 km/h.
An Irish driver in Mexico faces the same first-day problem as anywhere on the Continent: the road has flipped. Mexico then adds its own hazards, from speed bumps to night-time risks, and Ireland’s foreign ministry has clear advice on both.
The licence
Mexico’s federal road regulation requires you to carry a valid licence, and the Department of Foreign Affairs tells Irish travellers to bring a full Irish driving licence and adequate insurance. Mexico is not a party to the 1949 Geneva Convention under which Ireland issues international permits, so an IDP is optional; some hire desks like one as a Spanish-readable extra. The Driving Permit Checker covers onward trips.
Left to right
Ireland keeps left; Mexico keeps right. The risky moments are leaving the rental lot, the first roundabout turning anticlockwise and the reflex glance the wrong way. Start on quiet roads, not in Mexico City traffic.
Topes, toll roads and daylight
The tope is a speed bump placed on urban stretches and near settlements, and the federal regulation says to cross one at no more than 5 km/h. On federal roads cars may travel at up to 110 km/h where signs allow; states and towns post their own lower limits. The DFA advises keeping road travel to daylight hours, using toll (cuota) roads rather than free (libre) ones, and notes illegal roadblocks in Guerrero, Oaxaca and Chiapas. Expect vehicles that ignore limits, skip indicators or run red lights.
Alcohol
On federal roads private drivers may not exceed 0.8 g per litre of blood or 0.4 mg per litre of breath, and states set their own rules. Ireland’s limit is 50 mg per 100 ml. Keep it at zero; the DFA warns of detention, fines and bans. 911 reaches emergency services. Our Mexico driving guide has the state-level detail.

Mexico drives on the right; Ireland drives on the left. Roundabouts turn anticlockwise and junction instincts are mirrored, so take your first drive somewhere quiet.
Topes are speed bumps on urban stretches and near settlements, and the federal regulation says to cross them at no more than 5 km/h. Hitting one fast can damage a low hire car.
