Can an American Drive in Latvia? — IDP Recommended, Winter Tyres Required
United States
Latvia
Yes — an American licence holder can drive in Latvia, with an International Driving Permit recommended to carry alongside it. You stay on the right as at home, but two things differ: winter tyres are legally required in the cold season, and the drink-drive limit is a tighter 0.05, not 0.08.
Latvia is an easy place for an American to drive — right-hand traffic, modern enough roads, an EU member with clear rules. The differences from home are small but specific, and two of them carry real penalties.
The verdict for American licence holders
You can drive in Latvia on your US licence, and an International Driving Permit is recommended to carry with it. The IDP acts as a recognised translation of your licence for police and rental desks, and it is worth the few dollars to arrange before you fly. Keep your US licence, the IDP and your passport together.
You keep your side — but pick up two new rules
The good news for an American driver is that Latvia drives on the right, exactly as at home, so there is no side switch to relearn. What does change are two rules that do not exist the same way in most US states. First, winter tyres are compulsory in the cold season — not a recommendation, a legal requirement, and enforced because Baltic winters genuinely need them. A rental hired in season comes fitted; if you drive in from elsewhere, this is on you. Second, the drink-drive limit is 0.05, tighter than the 0.08 used across most of the US, so the margin you might assume at home does not exist here.
Speeds, the Via Baltica and roadside fines
Towns are 50 km/h, rural roads 90 and motorways 110 — broadly similar to home, but the headline route, the busy Via Baltica corridor between the Baltic capitals, mixes fast through-traffic with rough patches and heavy lorries. Away from it, rural surfaces deteriorate quickly. Speeding penalties start modestly, around EUR 30-40 for a minor breach, paid roadside, so carry a card or cash. Required kit includes a warning triangle, reflective vest, first-aid kit and fire extinguisher — keep them in the car. The emergency number is 112, and petrol runs about €1.58 a litre.

Winter tyres in Latvia — 2026–27 season
Winter tyres are compulsory on fixed dates in Latvia: 1 Dec - 1 Mar.
- Legal winter tread minimum: 4 mm (3.0 mm for buses over 3.5 t; 2.0 mm for lorries) — not the 1.6 mm figure most guides quote, which is the year-round minimum.
- Accepted marking: 3PMSF (alpine snowflake) required
- Studded tyres: allowed in season
In Latvian the rule is ziemas riepas, and snow chains are sniega ķēdes — that is the wording on signs, in hire-car paperwork and on any penalty notice.
