32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Warning sign shape

Triangular with a red border and white ground; it announces a hazard ahead so the driver can adjust speed, but it does not itself impose a legal speed limit.

Continuous white centre line

A solid white line along the centre of the carriageway that may not be crossed; overtaking and U-turns across it are prohibited unless a specific exception applies.

Yellow diamond sign

A priority-road sign indicating that the driver has the right of way at the next junction; the priority ends at the next junction unless the sign is repeated.

Zebra crossing markings

White stripes across the carriageway marking a pedestrian crossing; pedestrians who have stepped onto it have absolute priority and vehicles must stop.

Right-hand rule

At an unmarked junction of roads of equal status, the driver must give way to vehicles approaching from the right, unless signs or signals state otherwise.

Turning left obligation

A driver turning left must yield to oncoming vehicles proceeding straight or turning right, and must also give way to pedestrians on the road being entered.

Two-second rule

Minimum following gap in dry conditions equals the distance covered in two seconds; in rain, darkness or poor visibility the gap should be doubled.

Overtaking prohibitions

Overtaking is forbidden at pedestrian crossings, at level crossings and across a continuous centre line, and must be abandoned whenever a hazard develops.

Flashing yellow signal

At a junction it means proceed with caution and apply the ordinary right-of-way rules; it grants no priority over other traffic.

Green light meaning

Traffic may proceed, but the green light does not confer absolute priority; the driver must still yield to vehicles or pedestrians already lawfully in the junction.

Controller arm raised

A traffic controller's vertically raised arm means stop for all directions; the controller's signals override fixed lights and road signs.

Red cross lane signal

An overhead red cross marks a lane closed to traffic; drivers must leave that lane safely and may not continue in it.

Minimum tyre tread

Passenger car tyres must have at least 1.6 mm tread across the central three-quarters of the width and around the entire circumference.

Winter tyre requirement

When driving on snow or ice, winter tyres with at least 4 mm tread are required on all wheels of the vehicle.

Mandatory vehicle equipment

Bulgarian-registered vehicles must carry a first-aid kit, warning triangle, fire extinguisher and reflective vest, presented at roadside checks when requested.

Brake fluid replacement

Brake fluid absorbs moisture over time and is normally replaced every two years; a spongy brake pedal indicates air or moisture in the system.

Stopping distance formula

Total stopping distance equals the reaction distance travelled during about one second plus the braking distance, which grows with the square of speed.

Aquaplaning response

When water lifts the tyres off the road, ease off the accelerator, hold the steering steady and avoid sudden braking until grip returns.

Alcohol limit

A blood alcohol concentration of 0.5 g/L or more is an offence; novice and professional drivers are subject to a zero limit.

Fog driving lights

In fog use dipped beams or fog lamps rather than main beams, because main beams reflect off water droplets and reduce visibility further.

Documents carried while driving

The driver must carry a valid licence, vehicle registration certificate, compulsory third-party insurance policy and valid technical inspection certificate.

Compulsory liability insurance

Third-party liability insurance covers damage caused to other parties; it does not compensate damage to the insured vehicle itself.

Refusing a breath test

Refusing a roadside breath or drug test is an offence with consequences comparable to driving while intoxicated, including fines and licence measures.

Penalty point accumulation

Penalty points accumulate on the driving licence; reaching the statutory maximum leads to suspension and re-examination before the licence is restored.

Emergency number 112

The single European emergency number; report the exact location, the number of casualties and the nature of injuries before following operator instructions.

Warning triangle placement

On a road, place the warning triangle at least 50 metres behind the vehicle, switch on hazard lights and switch off the engine before assisting.

Adult CPR ratio

For adult CPR give chest compressions at 100-120 per minute, 5-6 cm deep, in a ratio of 30 compressions to 2 ventilations.

Severe bleeding control

Apply firm direct pressure with a clean dressing; a tourniquet is reserved for limb bleeding that cannot be controlled by pressure alone.

Recovery position

An unconscious casualty who is breathing is placed on the side with the airway open, then breathing is monitored continuously until emergency services arrive.

Eco-driving gear changes

Changing up early, at roughly 2000-2500 rpm in a petrol engine, lowers fuel consumption and emissions while reducing engine noise.

Engine idling

Idling wastes fuel and emits pollutants; switching off the engine during stops longer than about 30-60 seconds saves fuel and reduces emissions.

Regenerative braking

Electric and hybrid vehicles recover kinetic energy during deceleration and store it in the battery; smooth anticipatory driving maximises the energy recovered.
