You're on the right, the signs are in Cyrillic, and the speed cameras are average-speed. Here is everything you need to know — from swapping your licence to what happens if you hit something.
Bulgarian law mandates dipped headlights or daytime running lights at all times, 24 hours a day, 365 days a year. This is one of the first things visitors forget and one of the easiest roadside fines to collect.
Post-Brexit, vehicles registered in the UK must display a UK identifier — either on a new-style number plate alongside the Union Flag, or as a separate sticker on the rear. The old GB stickers and GB-initialled plates are no longer legally valid in Bulgaria.
If you are driving a right-hand drive (RHD) vehicle into Bulgaria, headlamp beam deflector stickers are compulsory. UK headlights are designed for left-hand traffic and will dazzle oncoming drivers in a right-hand traffic country. Beam converter stickers (widely available at Channel Tunnel terminals and UK motoring shops) redirect the beam pattern.
Vehicles already in a roundabout have priority over vehicles entering — the same as the UK. However, the signalling etiquette differs: Bulgarian drivers do not indicate when entering a roundabout. You only activate your right-turn signal when you intend to exit. Signalling too early will confuse other drivers.
The Traffic Police (known as KAT) and border control actively check vehicles. Missing documents can mean immediate fines, impoundment, or — in the case of a UK-registered vehicle — refusal of entry.
Valid, full national licence. Driver must be at least 18 years old.
Original V5C logbook (UK vehicles), or original hire car contract.
No physical Green Card required for UK vehicles since August 2021. Standard UK third-party cover is sufficient. Trailers over 750 kg need separate trailer insurance.
Compulsory for all vehicles. Deploy 30 m behind in towns, 50 m outside built-up areas.
Must be kept inside the cabin (not the boot). Any occupant who exits during a roadside emergency must wear it.
Functional and in-date. Must be secured within the vehicle and accessible.
Fully stocked. Legally required to treat minor injuries before emergency services arrive.
Compulsory for all right-hand drive vehicles to prevent blinding oncoming drivers.
Bulgaria has a "clean car" mandate. Driving a vehicle so dirty that its number plates or lights are obscured is a formal offence, with fines up to €150 and potential plate removal. This primarily affects muddy vehicles coming from rural roads in winter.
Minimum hire age is generally 21, though some providers require you to have held your licence for at least one year. Rental agencies will require your licence and a passport. Critically, if you plan to drive across the border into another country in a rental car, you must obtain explicit written permission from the hire company in advance — border officials will impound the vehicle otherwise.
As a UK licence holder living in Bulgaria, you have exactly one year from the date your first Bulgarian residence document is issued to exchange your UK licence for a Bulgarian one. Miss this deadline and you are classified as an unlicensed driver. Your insurance becomes invalid. Any accident becomes your full financial liability.
Once the grace period expires, driving on your UK licence is treated the same as driving with no licence at all. Administrative fines range from €50 to €150 under Article 177 of the Road Traffic Act. More seriously, both your third-party liability (TPL) insurance and any Casco policy become void — meaning the insurance company can legally refuse to pay out in the event of a collision.
The exchange process does not require you to sit a new theory or practical driving test. You are exchanging the piece of plastic, not re-qualifying. The process is managed by the Traffic Police (KAT) at the Regional Directorate of the Ministry of Interior for your registered address.
The standard fee for a Category B exchange is €12.50 for those under 58, or €5.50 for those aged 58 to 70. Standard processing takes up to 30 days. An express service halves the wait to 10 days but doubles the fee. The resulting Bulgarian licence is valid for 10 years.
If you already hold a driving licence from an EU or EEA member state, it is valid indefinitely in Bulgaria and does not need to be exchanged, though you may choose to do so voluntarily for convenience.
Permanently importing a vehicle requires a visit to KAT. Budget between €1,000 and €2,000 for the first year, covering taxes, insurance, and administrative fees. The main cost components are:
One-off environmental fee on first registration: €200–€300 depending on the vehicle's age and emissions standard.
Administrative processing and new plates: €50–€200.
Municipal tax based on engine power (kW), age, and Euro emission standard: typically €130–€250 per year.
Third-party liability ("Гражданска отговорност") is mandatory. Annual premium: typically €180–€200.
Bulgaria's equivalent of the MOT is the GTP (Годишен технически преглед — Annual Technical Inspection). New passenger cars are first tested in their third year, again in their fifth, then annually thereafter. Taxis and commercial vehicles over ten years old are tested every six months.
Since a major legislative reform, it is legally impossible to pass a GTP inspection if any unpaid traffic fines are registered against the vehicle or its listed owner. The inspection software automatically cross-references the Ministry of Interior's database. Pay your fines before you book the MOT.
Bulgarian inspection stations are only permitted to test vehicles registered in Bulgaria. If you are driving on UK plates temporarily, your valid UK MOT certificate is what matters. Operating without a valid home-country MOT risks a fine of up to €250 and confiscation of your registration document.
Speed limits are categorised by road type and vehicle class. The network of average-speed cameras on motorways and main roads is expanding — point-to-point calculations mean brief sprints above the limit no longer go undetected.
The 140 km/h motorway limit (approximately 87 mph) is higher than anything you will have experienced on UK roads. However, average-speed camera networks on Bulgarian motorways are now operating, and speeding fines scale steeply — exceeding the limit by more than 50 km/h results in a €360 fine plus a three-month licence suspension.
At any unmarked junction with no signage, the vehicle approaching from the right has absolute right of way. This applies in residential streets, rural villages, and any road without priority signage. In the UK this rule barely exists in practice. In Bulgaria it is everywhere. Always scan right at any uncontrolled junction.
Where a STOP sign is present, Bulgarian law requires a full, complete halt at the line — even if you can see clearly in both directions and the road is empty. Rolling through a STOP sign is treated as running a red light: €75 and 10 penalty points.
The green light flashes for 2–3 seconds before turning yellow. This is a warning, not an invitation to accelerate. Clear the junction safely.
Means caution — proceed carefully. Often deployed at intersections with active pedestrian crossings. Does not require a full stop unless other traffic demands it.
In cities such as Sofia, trams have absolute right of way in virtually all traffic scenarios — regardless of what the lights or road markings say. Always yield to trams.
Flashing headlights at oncoming traffic is a deeply entrenched cultural norm in Bulgaria. It almost always means one of two things: there is a police speed trap ahead, or there is a serious hazard on the road. Unlike in the UK where flashing lights can mean "go ahead", here it is a warning. Take it as one.
A brief double-flash of hazard lights from the vehicle in front means "thank you" — typically after you have given way or allowed them to merge. It is technically against the strict letter of the traffic code, but universally understood and used.
Any child under the age of 3, or any child under 150 cm in height regardless of age, must be in a properly approved child safety seat. Children under 12 are prohibited from sitting in the front passenger seat under any circumstances.
Using the horn within urban areas is prohibited between 22:00 and 06:00, and between 12:00 and 16:00 (the afternoon rest period). The sole legal exception is to prevent an immediate accident. The quiet hours are strictly observed and violations draw immediate attention from local residents.
Bulgaria uses a fully digital tolling system. Physical windscreen stickers were abolished in 2019. An e-Vignette is required for all motorways, expressways, and primary national roads outside municipal boundaries. There is nothing to display — the system reads your number plate.
Following Bulgaria's entry into the Eurozone on 1 January 2026, the e-Vignette pricing has been converted at the fixed rate of 1 EUR = 1.95583 BGN. All prices are now in Euros.
Purchase online at bgtoll.bg, via the official mobile app, at border crossing kiosks, post offices, or major fuel station networks. When entering your registration number, do not use spaces, hyphens, or dots. The most common error is confusing the digit 0 with the letter O — the system treats them as different characters and your vignette will be invalid.
Enforcement is by ANPR cameras on overhead gantries plus mobile units. The standard fine is €150 for passenger vehicles. However, if you pay a “compensatory fee” on the same calendar day as the violation, the fine drops to €50 — roughly the price of an annual vignette. The message is clear: just buy one.
Bulgaria's penalties for drink and drug driving are among the most severe in Europe, with criminal sanctions kicking in at relatively low blood alcohol levels. Recent Penal Code amendments have introduced mandatory vehicle confiscation for serious offences. Read this section carefully.
The legal limit for standard drivers is 0.5‰ (0.05%). For novice drivers — those who have held their licence for less than two years — the limit is absolute zero: 0.00%.
| BAC Level | Penalty |
|---|---|
| 0.5‰ – 0.8‰ | Administrative Fine of €255 + 6-month licence suspension |
| 0.8‰ – 1.2‰ | Administrative Fine of €510 + 12-month licence suspension |
| Over 1.2‰ | Criminal 1 to 3 years imprisonment + fine of €510–€2,555 + vehicle confiscation |
| Repeat offender (>0.5‰) | Criminal 1 to 5 years imprisonment + fine of €1,020–€5,110 + vehicle confiscation |
If you are convicted with a BAC over 1.2‰, or test positive for a controlled substance through laboratory analysis, and you are the sole legal owner of the vehicle, the court is mandated to confiscate it on behalf of the State. If you are driving a vehicle you do not own (a rental, a company car, a family member's vehicle), the vehicle is protected from seizure — but you face an additional financial penalty equivalent to the vehicle's assessed market value.
Police can carry out random drug screening using the Dräger DrugTest 5000, a saliva-based device that screens simultaneously for eight substance classes including cannabis (THC), cocaine, opiates, amphetamines, benzodiazepines, and methadone.
Bulgarian law penalises the mere presence of substances in your body, regardless of quantity or impairment. The Dräger device is known to produce false positives triggered by certain prescription medications, codeine-based painkillers, and antihistamines. If you test positive at the roadside:
Refusing to provide a breath or saliva sample following an accident is classified as a criminal act. Penalties include up to one year in prison, a fine of €1,020–€1,280, immediate deduction of 15 penalty points, and a minimum two-year licence suspension. There is no legal benefit to refusing — only additional punishment.
Bulgaria's mountain terrain produces genuinely severe winters. The Balkan, Rhodope, and Rila ranges regularly see deep snow and ice from November through to March. The state enforces strict seasonal equipment requirements and they are actively checked.
All vehicles must be fitted with winter tyres (M+S or 3PMSF symbol) or summer tyres with a minimum 4 mm tread depth across the full circumference. Studded tyres are completely prohibited on Bulgarian roads.
You must carry a set of appropriately sized snow chains during this extended period. Chains become legally compulsory on mountain passes marked with a blue sign showing a chained tyre. Maximum speed with chains engaged: 50 km/h.
Several major passes — including Shipka and sections of the E79 — are closed or chained-only during heavy snowfall. Real-time road condition information is available from the Road Infrastructure Agency (api.bg). Plan mountain routes with flexibility and do not rely solely on GPS navigation in winter.
Urban parking in Sofia (and most larger Bulgarian cities) operates on a colour-coded zone system. Payment is almost entirely app or SMS-based — you will struggle to find coin-operated machines.
Payment options include the official Urbo app, Viber chatbot, or SMS (using a Bulgarian SIM). Foreign visitors without a local SIM must use the app or find a parking attendant for pre-paid coupons. SMS payment requires a Bulgarian telecoms account — do not rely on it with a UK SIM.
Electric and hydrogen vehicles have historically been permitted to park free in both zones, but this is being phased out as EV adoption grows. From 2026, free parking is limited to the first three hours, after which standard rates apply. Check current rules when you arrive — the policy is still being settled.
Bulgarian licences carry a maximum of 39 points. Drivers begin with the full allocation and lose points for serious infractions. Reach zero and your licence is revoked. Reinstatement requires a psychological assessment and a full re-test — both theory and practical. Expats who exchange their UK licence are fully integrated into this domestic system.
| Violation | Fine / Penalty |
|---|---|
| Speeding: 11–20 km/h over limit | €25 |
| Speeding: 21–30 km/h over limit | €50 |
| Speeding: 31–40 km/h over limit | €150–€200 |
| Speeding: over 50 km/h over limit | €360 + 3-month suspension |
| Running a red light or STOP sign | €75 + 10 points |
| Failing to yield at pedestrian crossing | €75 + 10 points |
| Using a handheld mobile phone | €25 |
| Not wearing a seatbelt | €25 |
| No headlights during daylight | €25 |
| Driving without documentation | €15 (missing docs) / €50–€150 (unlicensed) |
| Unpaid e-Vignette | €150 (or €50 same day) |
Fines issued during a traffic stop are presented as a formal "penal decree". Camera-generated violations are mailed as "electronic slips" to the registered owner's address. You can check and pay outstanding fines at ePay.bg or via the Ministry of Interior's online portal using your driving licence number and EGN/LNCh identification number.
Police vehicles carry mobile POS terminals. You can pay minor fines immediately by card. It is strictly illegal for officers to accept cash roadside — if a police officer demands cash for a fine, refuse and request the formal ticket instead. Fines paid within 14 days of issue are routinely subject to a 30% discount.
Bulgarian law is very specific about what you must do at the scene of a collision. Following the wrong procedure can invalidate your insurance claim entirely.
With injuries involved, the accident is automatically classified as a serious incident. Call the emergency number 112 for police and ambulance. Do not consume alcohol, food, or medication before the police arrive — you will be breath-tested and drug-tested at the scene.
If both vehicles are Bulgarian-registered and both drivers fully agree on what happened, you may complete a Bilateral Ascertainment Protocol (European Accident Report Form) without involving the police. Your insurance company provides this form when you purchase a policy.
Call 112, state that a foreign-registered vehicle is involved, and wait for the Traffic Police. The official police report is required by Bulgarian and international insurers to process a cross-border claim.
If the at-fault driver has no insurance, or flees the scene, compensation for victims is administered by the Bulgarian Guarantee Fund. Report the incident to police immediately to preserve your claim.
All information is drawn from the Bulgarian Road Traffic Act, KAT, the National Toll Administration, and the Bulgarian Penal Code as amended through 2025–26.
Bulgarian road law has changed significantly in recent years. This guide reflects the rules in force as of April 2026, including the Euro transition and new drink-driving legislation.
