Driving in Bulgaria on a US Licence — E-Vignette First, 140 km/h Motorways

The detail that trips up American visitors in Bulgaria has no equivalent on US roads: the e-vignette. There are no toll plazas here. Instead, every motorway and major expressway requires a prepaid electronic permit linked to your licence plate, and overhead cameras read plates to enforce it. You buy it online, at a border kiosk or at a petrol station before you join the motorway — a weekend pass is cheap — but a car caught without one collects a fine that wipes out any saving. If your route crosses into neighbouring Romania, Serbia or Greece, the rules shift again; our vignette countries guide maps the region.

Paperwork next: an International Driving Permit is strongly recommended for American drivers. Your state licence is technically usable, but Bulgarian police stops can escalate fast without the IDP’s certified translation, and rental desks may refuse you. AAA issues it before you travel; you can’t get one in Bulgaria. Carry it with your US licence and passport.

On the road, the surprise runs the opposite way to most of Europe — Bulgaria’s motorway limit is a fast 140 km/h, well above anything US highways permit. That sounds liberating, but the motorway network is patchy and the moment you leave it the roads roughen quickly: rural surfaces are uneven, lane discipline is loose, and overtaking can be aggressive. Drive to the road, not the sign. Cameras are widespread, and going 20+ km/h over can mean EUR 50–100, with roughly 10 km/h over around EUR 25.56 (about EUR 25).

Alcohol is stricter than home: 0.05 BAC versus the US 0.08, enforced with roadside tests. Read the Bulgaria driving guide for the mandatory in-car equipment (triangle, vest, kit, extinguisher), check a likely penalty on the Speeding Fine Calculator, and if a camera ticket follows you to the rental return, our note on who pays driving fines abroad explains how it reaches you. Emergencies: 112.

Bulgaria adopted the euro on 1 January 2026. Figures previously published in leva were converted at the fixed statutory rate of 1.95583 leva to the euro.00 to the euro.
