Driving in Bulgaria - Road Rules and Tips for Foreign Drivers

Bulgaria is a popular destination for road tourism and transit traffic between Western and South-Eastern Europe. The road network covers the entire country, and motorways connect Sofia with the main border crossing points.

If you are driving in Bulgaria for the first time, it will be useful to familiarise yourself with the rules and particularities of local traffic in advance. Legislation changed significantly from September 2025, including the introduction of average speed enforcement on motorways.

In this article you will find concise information on speed limits, toll charges, required documents, and the practical aspects of driving in the country – everything you need to travel safely and in compliance with the law.

Basic Traffic Rules in Bulgaria

Traffic in Bulgaria is right-hand – vehicles drive on the right-hand side and overtake on the left. For drivers from countries with left-hand traffic, such as the United Kingdom, this requires special attention, particularly during the first few hours after entering the country.

Vehicles approaching from the right have right of way at unmarked junctions. At marked junctions, road signs determine who has priority. Where a sign reads Stop, the driver is required to come to a complete halt, even when there is clear visibility of oncoming traffic.

Vehicle headlights are compulsory around the clock – both during the day and at night. This rule has been in place for years and is strictly enforced. Parking in yellow zones is prohibited, while blue zones indicate paid parking with a time limit.

Mandatory documents when driving are a valid driving licence, a valid identity document, the vehicle registration certificate, and third-party liability insurance. When driving a rental car, the rental company provides these documents.

Speed Limits and the New Average Speed Enforcement

The standard speed limits for passenger cars in Bulgaria are as follows: in built-up areas – 50 km/h, outside built-up areas – 90 km/h, on expressways – 120 km/h, on motorways – 140 km/h. The limits for rental cars are the same, as most rental vehicles fall under category B.

From 7 September 2025, section control came into force in Bulgaria – the measurement of average speed over defined stretches of motorways and expressways. Cameras integrated into the toll system record the time a vehicle takes to cover a given section and calculate the average speed.

The number of certified sections is growing gradually. Starting with around 22 sections, the system is expanding to cover an increasing number of kilometres of the national network. Violations are recorded automatically and fines are sent to the address of the vehicle's registered owner.

The fine for exceeding the speed limit by more than 40 km/h outside a built-up area is 600 leva. For smaller violations the penalty varies according to the scale of the infringement. Unmarked patrol vehicles with uniformed officers have the right to stop and fine drivers – a new measure introduced in 2025.

Alcohol, Seat Belts and Mobile Phones

The permitted blood alcohol level when driving in Bulgaria is 0.5 per mille for experienced drivers. For newly qualified drivers with less than two years of experience the limit is stricter – 0.2 per mille. Exceeding these levels carries penalties including fines and disqualification from driving.

Seat belts are mandatory for all occupants of the vehicle – both on the front and rear seats. Children under 150 centimetres in height must travel in an approved child seat or booster appropriate for their weight.

Using a mobile phone while driving is prohibited without a hands-free device. Holding a phone in hand while driving carries a fine. An increasing number of traffic police officers are targeting this specific offence in urban areas and along motorway sections.

In the event of an accident, the driver is required to place a warning triangle behind the vehicle and notify the police. When driving a rental car, you should also contact the rental company immediately for instructions. Carrying a high-visibility vest is strongly recommended and in some situations is compulsory.

Toll System and Electronic Vignette

An electronic vignette is required to use the national road network in Bulgaria. It is mandatory for foreign-registered vehicles as well – the system allows purchase for registrations from all countries.

The vignette is entirely electronic – it is not affixed to the windscreen but is registered directly against the vehicle's licence plate number in the central system. During a roadside check, the driver is not required to present a paper document. Validity can be verified online at bgtoll.bg by entering the registration number.

Current e-vignette prices from May 2025 for passenger cars up to 3.5 tonnes are: weekly – 15 leva, weekend – 10 leva (from Friday 12:00 to Sunday 23:59), monthly – 30 leva, quarterly – 54 leva, annual – 97 leva.

For short visits to the country, the weekly or weekend vignette is the most practical option. Purchase is possible at the border crossing point, online at bgtoll.bg, or via the bgtoll mobile application. Payment by bank transfer requires at least three working days in advance due to the technical activation process.

Heavier vehicles over 3.5 tonnes do not use a vignette but pay a per-kilometre toll charge on motorways. For passenger cars no per-kilometre toll is charged – only the vignette is required.

Driving without a valid vignette is detected automatically by cameras. The fine is substantial and the system operates without exceptions for foreign-registered vehicles.

Road Conditions and Practical Tips

The quality of the road network in Bulgaria varies considerably. Motorways are well maintained and offer comfortable driving. Smaller roads in mountainous and remote areas may have poorer surfaces, tight bends, and no crash barriers.

During winter, mountain passes may be closed or require snow chains. Before travelling in winter it is sensible to check the current road conditions. During the tourist season, traffic around Black Sea resorts and in Sofia can be heavy, particularly on Friday afternoons.

Parking in larger cities requires attention. In blue and green zones a parking fee is charged for a set period. Illegally parked vehicles may be towed, and retrieving them involves a fee and a significant loss of time.

Petrol stations along the main road arteries are well represented. Smaller and mountain roads may have stations spaced far apart. On such routes it is sensible to fill up with a reserve of fuel before heading onto secondary roads.

Road Signs, Traffic Lights and Parking

Road signs in Bulgaria follow the European standard and are recognisable to drivers from EU countries. One difference from Western European practice is the traffic light sequence – the amber light precedes red and signals a mandatory stop. It does not mean prepare to move, but stop.

Pedestrians on a designated crossing have absolute right of way. Failing to give way to them is an offence for which police issue a fine. In urban areas it is common for pedestrians to cross busy boulevards – be prepared to stop in good time.

When approaching a roundabout, entering vehicles must give way to those already circulating inside. The roundabout sign makes this explicit. In smaller towns and villages not all road users are fully aware of this rule, so it is advisable to reduce your speed in advance.

In mountain areas, follow road signs for maximum speed in bends carefully. The limits there are set based on actual measurements of the safe speed for the pass. Ignoring them can be dangerous, particularly on wet or icy road surfaces.
