Bulgaria Driving Rules for Americans (2026)
Bulgaria drives on the right, enforces strict speed limits (50/90/140 km/h), requires a vignette on all motorways, and uses Cyrillic road signs. Carry your US license plus an IDP at all times.
Bulgarian traffic law is codified in the Road Traffic Act (ЗДвП), enforced by Пътна полиция (KAT — Traffic Police).
Which Side of the Road?
Bulgaria drives on the right side of the road and overtakes on the left — the same as the United States and most of continental Europe. The driver's seat is on the left. No reverse-side adjustment needed.
Motorways (in Bulgarian: автомагистрала / avtomagistrala, prefixed "A") are dual carriageway. Use the right lane for normal driving and the left lane only for overtaking — Bulgarian drivers will flash high beams at you if you camp in the left lane.
Bulgaria Speed Limits
Default limits apply unless otherwise signed. KAT speed cameras (stationary and mobile) are heavily deployed on motorways and the approaches to Sofia, Plovdiv, Burgas, and Varna.
| Road Type | Cars / Motorcycles | Mph Equivalent |
|---|---|---|
| Urban areas (built-up) | 50 km/h | ~31 mph |
| Open roads (rural) | 90 km/h | ~56 mph |
| Expressways (4-lane non-motorway) | 120 km/h | ~75 mph |
| Motorways (A1 Trakia, A2 Hemus, A3 Struma, A4 Maritsa) | 140 km/h | ~87 mph |
| Towing a trailer (any road) | Limits reduced ~20 km/h | — |
| New drivers (license <2 years) | Lower limits apply | — |

The Vignette (Vinjetka) — A Bulgaria Driving Essential
Every car using a Bulgarian motorway or main inter-urban road must carry an electronic vignette. This is not optional, and it is the single most expensive mistake American visitors make in Bulgaria.
- Weekend pass (3 days): ~€10 / 20 BGN
- 7 days: ~€18 / 35 BGN
- 30 days: ~€30 / 60 BGN
- 1 year: ~€87 / 170 BGN
Rental cars usually have an active vignette pre-loaded — always verify at pickup in writing. If you're driving your own car or crossing the border, buy a vignette online at bgtoll.bg, at any large petrol station (Lukoil, OMV, Shell, Eko), or at the border crossing before you reach the motorway.
Penalty: Up to 1,800 BGN (~$1,000 USD) for driving on a tolled road without a valid vignette. Cameras automatically scan every license plate.
Alcohol and Drugs — Zero Tolerance Approach
Bulgaria has a stricter BAC limit than the United States. KAT officers carry portable breathalyzers and routinely test at checkpoints, especially on weekend evenings and after holiday weekends.
- 0.05% BAC (0.5 g/L): Standard limit for experienced drivers.
- 0.00% BAC: Strictly zero for new drivers in their first 2 years and for professional drivers.
- 0.05% to 0.12%: Fine of 500–1,000 BGN plus 6-month license suspension.
- Above 0.12%: Treated as a criminal offence — possible jail time, license revocation, and a fine starting at 1,000 BGN.
- Drugs: Zero tolerance. Roadside drug tests are now standard at major KAT operations.
Practical advice: do not drive after any alcohol in Bulgaria. Even one beer can push a small adult over 0.05%, and the consequences include criminal liability and license loss.
Required Equipment and In-Car Rules
- Seat belts: Mandatory for all occupants in all seats. Fine ~50–100 BGN per violation.
- Daytime headlights: Required from November 1 through March 1. Headlights on, daytime or night. ~50 BGN fine for non-compliance.
- Mobile phones: Hands-free only. Holding a phone while driving costs 100–200 BGN.
- Child seats: Required for children under 150 cm or under age 12.
- Reflective vest: One vest per vehicle, accessible from the driver's seat (i.e., not in the trunk).
- Warning triangle: Must be in the vehicle.
- First aid kit + fire extinguisher: Required by law in all vehicles.
- Snow chains/winter tires: Winter tires required Nov 15–Mar 1 in many regions; snow chains required on signed mountain routes.

Cyrillic Road Signs — What Americans Need to Know
Bulgaria uses the Cyrillic alphabet. Highway and tourist signs are increasingly bilingual (Cyrillic + Latin) on motorways and around Sofia, but smaller roads, parking signs, and rural turn-offs are still Cyrillic only.
| Cyrillic | Latin | English / Meaning |
|---|---|---|
| София | Sofia | Capital city |
| Пловдив | Plovdiv | 2nd largest city |
| Варна | Varna | Northern Black Sea |
| Бургас | Burgas | Southern Black Sea |
| Велико Търново | Veliko Tarnovo | Old capital |
| СТОП | STOP | Stop |
| Бензин / Дизел | Benzin / Dizel | Petrol / Diesel |
| Изход | Izhod | Exit |
| Център | Tsentar | Center / Downtown |
Shape and color conventions follow the European Convention on Road Signs and Signals — round red signs are prohibitions, triangular red signs are warnings, blue rectangles are information. The shapes are the same as everywhere in Europe; only the lettering differs.
Right-of-Way, Roundabouts, and Intersections
- Roundabouts: Traffic inside the roundabout has priority — yield on entry. This is the European standard, opposite to some older Bulgarian rules.
- Unmarked intersections: Yield to traffic coming from your right.
- Yield signs (ОТСТЪПИ): Triangular sign pointing down. Always yield to the cross street.
- Pedestrian crossings: Pedestrians have absolute priority at marked zebra crossings. Failing to stop costs 100–200 BGN.
- Trams: In Sofia, trams have right of way. Never overtake a stopped tram letting off passengers.
- Emergency vehicles: Pull over and stop for sirens — police, ambulance, fire.
