- Bulgarian motorway speed limit
- The maximum speed for cars up to 3.5 tonnes on Bulgarian motorways is 140 km/h; the limit drops to 100 km/h for heavier vehicles and those towing trailers.
- Two-second rule
- A following-distance rule: choose a fixed roadside object, count two seconds after the vehicle ahead passes it; if you arrive sooner, you are too close.
- Zebra crossing priority
- Pedestrians on a marked zebra crossing have priority; drivers must stop before the crossing when a pedestrian has stepped onto it or clearly intends to cross.
- Solid white line meaning
- A continuous white line along the carriageway may not be crossed, except for a permitted manoeuvre such as turning into a property or avoiding a blockage.
- Flashing amber signal
- At a pedestrian crossing, a flashing amber signal means proceed only if no pedestrian is on the crossing; pedestrians retain priority over vehicles.
- Yellow box junction rule
- A yellow box junction may not be entered unless the exit is clear, so that vehicles do not block the junction when traffic is congested.
- Category B licence scope
- Category B covers motor vehicles up to 3,500 kg with up to eight seats excluding the driver; a trailer up to 750 kg may be towed.
- Bulgarian alcohol limit
- The general blood alcohol limit for drivers in Bulgaria is 0.05 percent; novice and professional drivers must have zero alcohol in the blood.
- Load projection marking
- A load projecting more than one metre beyond the rear of a vehicle must be marked with a warning sign, especially during darkness or poor visibility.
- Maximum vehicle width
- The maximum permitted width of a vehicle including its load is 2.55 metres; maximum height is 4 metres and maximum length is 12 metres.
- Alcohol elimination rate
- The liver metabolises roughly 0.1 to 0.15 grams of alcohol per litre of blood per hour; coffee, food, or fresh air do not speed this up.
- Fatigue remedy
- The only effective remedy for driver fatigue is to stop and rest, ideally a short nap of 15 to 20 minutes; stimulants only mask the problem temporarily.
- Aquaplaning response
- When tyres lose contact with water on the road, ease off the accelerator, avoid hard braking, and steer gently until grip returns.
- Skid correction technique
- When a vehicle begins to skid, steer in the direction of the skid and avoid sudden braking or acceleration until the tyres regain grip.
- Fog driving lights
- In fog, use dipped headlights or fog lamps; do not use main beam because it reflects off the fog and reduces visibility further.
- Tyre tread minimum
- The minimum legal tread depth for car tyres is 1.6 mm across the central three-quarters of the tread; tyres must show no cuts or exposed cords.
- Brake fluid replacement
- Brake fluid absorbs moisture over time and should be replaced roughly every two years; a spongy pedal may indicate air or fluid loss.
- Red warning light
- A red warning light on the dashboard, such as oil pressure or brake warning, means stop as soon as it is safe and investigate.
- Warning triangle distance
- On ordinary roads, place the warning triangle at least 30 metres behind the vehicle; on motorways place it further back for safety.
- CPR compression rate
- Chest compressions during CPR should be performed at 100 to 120 per minute, 5 to 6 cm deep, and continued until help arrives.
- Recovery position use
- An unconscious but breathing casualty should be placed in the recovery position, and breathing must be monitored continuously until emergency services arrive.
- Burn first aid
- Cool a burn with clean running water for at least 10 minutes; do not apply ointments or ice, and do not remove clothing stuck to the burn.
- Daily driving limit
- EU rules allow a maximum of 9 hours of daily driving, extendable to 10 hours twice a week; the weekly maximum is 56 hours.
- Tachograph record retention
- Drivers must keep tachograph records for at least 28 days and make manual entries for activities not recorded automatically, such as other work.
- Passenger seat belt duty
- Passengers must wear seat belts where fitted, and the driver is responsible for ensuring that children use appropriate child restraints.
- Efficient gear changing
- Changing gear at around 2,000 to 2,500 rpm and accelerating smoothly reduces fuel consumption compared with high-revving, aggressive driving.
- Idling fuel waste
- Idling wastes fuel; switching off the engine when stationary for more than about 30 seconds saves fuel, except where restarting would be unsafe.
- Tyre pressure and fuel
- Correct tyre pressure reduces rolling resistance; under-inflated tyres can increase fuel consumption by several percent and risk overheating and blowouts.
- Catalytic converter fuel rule
- Catalytic converters reduce harmful emissions; leaded fuel must never be used in vehicles fitted with a catalytic converter because it destroys the catalyst.
- Braking distance scaling
- Braking distance increases with the square of speed: doubling speed from 50 to 100 km/h roughly quadruples the braking distance on the same surface.
- Lane closure signal
- A flashing red signal or a red cross displayed above a lane means the lane is closed; drivers must leave it and must not enter.
- Visual acuity requirement
- Category B drivers need corrected visual acuity of at least 0.5 in the better eye and 0.2 in the worse eye to meet fitness requirements.
