Road Traffic Law and Regulations (Закон за движението по пътищата)

  • Bulgarian traffic law is codified in the Road Traffic Act (ЗДвП); the right-hand traffic rule applies, with overtaking normally performed on the left.

  • A driver must carry a valid driving licence, vehicle registration certificate, compulsory third-party liability insurance (ГО) and, where required, a tachograph record and transport documents.

  • Seat belts are mandatory for the driver and all passengers; children under 12 or shorter than 150 cm must use an approved child restraint appropriate to their size.

  • The general urban speed limit is 50 km/h, outside built-up areas 90 km/h, and on motorways 140 km/h, unless signs state otherwise.

  • A pedestrian on a marked crossing has priority; the driver must slow down and stop when a pedestrian has entered or is about to enter the crossing.

  • Driving with a blood alcohol concentration above 0.5 ‰ is an offence; for novice drivers and professional drivers the tolerated limit is effectively zero.

  • Using a hand-held mobile phone while driving is prohibited; only hands-free equipment may be used.

  • At an unguarded level crossing the driver must stop, look both ways and proceed only when no train is approaching.

Road Signs, Markings and Traffic Signals

  • Signs are grouped by shape: triangles warn of hazards, circles impose prohibitions or orders, rectangles and squares give information, and octagons mean STOP.

  • A red-bordered circle with a number is a maximum speed limit; a blue circle with a number is a minimum speed or mandatory speed.

  • A continuous white centre line may not be crossed; a broken line may be crossed when overtaking or turning is safe and permitted.

  • A yellow zigzag or yellow kerb marking indicates a no-stopping zone, commonly at bus stops and pedestrian crossings.

  • Traffic light sequence: red, red plus amber, green, amber, red; a flashing amber light means proceed with caution.

  • A traffic controller's signals take priority over traffic lights, and traffic lights take priority over road signs, which take priority over markings.

  • Give-way signs (inverted triangle) require yielding without necessarily stopping; the STOP sign requires a full stop at the line.

  • Direction signs with a green background indicate motorway routes; blue backgrounds indicate ordinary roads outside built-up areas.

Safe Driving and Hazard Perception

  • The safe following distance in dry conditions is at least the distance travelled in two seconds; double it in rain and triple it on ice.

  • Braking distance grows with the square of speed: doubling speed quadruples the braking distance.

  • Total stopping distance equals reaction distance (speed × reaction time) plus braking distance.

  • In fog, use dipped headlights or fog lamps; do not use main beam, because it reflects off the fog and reduces visibility.

  • Aquaplaning occurs when tyres lose contact with a wet road; the response is to ease off the accelerator, avoid braking hard and hold the steering steady.

  • Blind spots must be checked by mirror and shoulder glance before changing lanes or pulling out.

  • On a motorway, keep right except when overtaking; the left lane is for overtaking, not for cruising.

  • Hazard perception means scanning far ahead, reading the road for junctions, parked vehicles and pedestrians, and anticipating rather than reacting.

Vehicle Categories

  • Category AM covers mopeds up to 45 km/h and 50 cc; category A covers motorcycles, with A2 and A1 as restricted sub-categories.

  • Category B covers cars up to 3,500 kg with up to eight seats; a B licence also permits towing a trailer up to 750 kg.

  • Category C covers goods vehicles over 3,500 kg, with a trailer up to 750 kg; category C1 covers goods vehicles from 3,500 to 7,500 kg.

  • Category D covers buses with more than eight passenger seats; D1 covers minibuses up to 16 seats.

  • Categories BE, CE and DE are trailer entitlements attached to the corresponding base category.

  • Drivers under 21 may not drive category C or D vehicles professionally; minimum ages are 18 for C and 21 for D.

  • A category C driver must hold a valid medical certificate and, for professional transport, a driver qualification card (code 95).

  • Vehicle categories are defined by maximum authorised mass, not by the vehicle's actual load at the time of driving.

Driving Licences and Driver Obligations

  • A driving licence is valid for ten years for categories B and C; the medical fitness certificate must be renewed every five years after age 60.

  • The licence must be carried while driving; failure to produce it on request by the police is an offence.

  • Points are recorded against the licence for traffic offences; accumulation of points can lead to suspension.

  • A driver must report a change of address and any medical condition affecting fitness to drive.

  • Professional drivers must hold a certificate of professional competence (CPC) and complete periodic training of 35 hours every five years.

  • The driver is responsible for the vehicle's roadworthiness before each journey, including tyres, lights, brakes and load security.

  • A driver involved in an accident must stop, render assistance, exchange details and notify the police where required.

Quick reference

Vehicle Technical Knowledge and Roadworthiness for Category C

  • The minimum tread depth for category C tyres is 1 mm across the central three-quarters of the tread; tyres must match in size and type on the same axle.

  • The air brake system must be checked for pressure build-up and leak-down before driving; a pressure drop with the engine off indicates a leak.

  • The tachograph must be calibrated every two years and sealed; tampering is an offence.

  • Daily checks cover lights, indicators, mirrors, wipers, horn, brakes, tyres, fluid levels and load security.

  • The ABS warning lamp must extinguish after the self-test; if it stays on, the vehicle should not be driven until checked.

  • The maximum authorised mass (MAM) and axle loads are stated on the vehicle plate; overloading is an offence and affects braking.

  • The exhaust brake or retarder must be used on long descents to prevent brake fade.

  • A category C vehicle must carry a warning triangle, a fire extinguisher and a first-aid kit.

  • A weekly rest is 45 hours, reducible to 24 hours under conditions that require compensation.

  • The tachograph records driving, other work, availability and rest; manual entries must be made where required.

  • Drivers must carry tachograph records for the current day and the previous 28 days.

  • The 4.5-hour rule is measured by the tachograph; a break cannot be replaced by other work.

Quick reference

Tachograph and Transport Documentation

  • A digital tachograph records speed, distance, driving time and driver activity; the driver card is personal and must not be shared.

  • The driver must insert the card at the start of the shift and remove it at the end, making manual entries for any gaps.

  • The tachograph must be calibrated every two years; a calibration plaque is displayed in the vehicle.

  • The driver must carry a driver card, a printout if required, the CMR consignment note for international carriage and the vehicle documents.

  • The CMR note is the international consignment note for road freight; it identifies the parties, the goods and the route.

  • A driver qualification card (code 95) proves CPC compliance and must be carried.

  • Records must be produced on request by enforcement officers; failure to produce is an offence.

  • Printouts must be signed by the driver when used to replace missing records.

First Aid, Emergency Situations and Accident Procedures

  • The first action at an accident scene is to secure the area: switch off engines, set the warning triangle and switch on hazard lights.

  • The emergency number in Bulgaria is 112; give location, number of casualties and hazards.

  • Do not move an injured person unless there is immediate danger such as fire or traffic.

  • The recovery position is used for an unconscious but breathing casualty; check breathing and clear the airway.

  • For severe bleeding, apply direct pressure with a clean dressing and elevate the limb if possible.

  • For a suspected spinal injury, keep the head and neck aligned and do not twist the casualty.

  • CPR ratio for adults is 30 chest compressions to 2 rescue breaths; compression depth is 5–6 cm at 100–120 per minute.

  • After an accident, exchange names, addresses, insurance details and registration numbers, and do not leave the scene without justification.

Environmental Protection and Fuel-Efficient Driving

  • Fuel consumption rises sharply above 90 km/h because aerodynamic drag increases with the square of speed.

  • Correct tyre pressure reduces rolling resistance; under-inflation increases fuel use and tyre wear.

  • Anticipatory driving, smooth acceleration and early gear changes reduce fuel consumption and emissions.

  • Idling the engine wastes fuel; switch off when stationary for more than a short period.

  • Roof racks and unnecessary loads increase drag and weight, raising fuel consumption.

  • Euro emission standards classify engines by pollutant output; low-emission zones may restrict older vehicles.

  • Regular servicing, clean air filters and correct engine oil reduce emissions and fuel use.

  • Using air conditioning increases fuel consumption; use ventilation at low speeds and air conditioning at high speeds.

  • The maximum gross combination weight for a road train is 40 t; for an articulated combination it is 40 t.

  • The trailer must be coupled with a safety connection and the breakaway cable must be attached.

  • The load must be secured with straps or chains rated for the load; the number of lashings depends on the load weight.

  • Overloading affects braking distance, tyre wear and stability; it is an offence.

Quick reference

Driving and Rest Periods (Additional)

  • A break of 45 minutes may be split into 15 minutes followed by 30 minutes; the order matters.

  • Daily driving time is measured between two daily rests; it may not exceed 9 hours, or 10 hours twice a week.

  • The weekly rest must be taken within six consecutive 24-hour periods from the end of the previous weekly rest.

  • A reduced weekly rest of 24 hours must be compensated by an equivalent period attached to another rest within three weeks.

  • The driver must record other work and availability; these count toward the 4.5-hour break rule.

  • The tachograph must be used correctly; manual entries are required for any period not recorded automatically.

  • The driver must carry the previous 28 days of records and produce them on request.

  • Rest periods must be taken away from the vehicle where possible; a break may be taken in the vehicle if it has a bunk.

Quick reference

First Aid, Emergency Situations and Accident Procedures (Additional)

  • The emergency number 112 works across the EU; give the location, the number of casualties and the hazards.

  • The recovery position protects the airway; it is used for an unconscious but breathing casualty.

  • For severe bleeding, apply direct pressure and, if possible, elevate the limb; do not remove an embedded object.

  • For burns, cool with water for at least 10 minutes and do not remove clothing stuck to the burn.

  • For a suspected spinal injury, keep the head and neck aligned and do not move the casualty unless there is immediate danger.

  • CPR for adults uses 30 compressions to 2 breaths at 100–120 per minute with a depth of 5–6 cm.

  • After an accident, exchange details, do not leave the scene and notify the police where required.

  • The warning triangle must be placed at a sufficient distance to warn approaching traffic.

Quick reference
