Bulgaria Theory Test C flashcards

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

Right-hand traffic rule

In Bulgaria traffic keeps to the right; overtaking is normally performed on the left, and the driver must return to the right lane after overtaking.

Urban speed limit

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

Alcohol limit

Driving with a blood alcohol concentration above 0.5 ‰ is an offence; novice and professional drivers are effectively subject to a zero limit.

Pedestrian priority

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.

Continuous centre line

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

Traffic light sequence

The sequence is red, red plus amber, green, amber, red; a flashing amber light means proceed with caution.

Priority of signals

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

Two-second rule

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 rule

Braking distance grows with the square of speed: doubling speed quadruples the braking distance, so stopping distance rises sharply.

Aquaplaning response

When tyres lose contact with a wet road, ease off the accelerator, avoid hard braking and hold the steering steady until grip returns.

Category C definition

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

Category D definition

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

Minimum age category C

The minimum age for category C is 18; professional driving of C vehicles requires age 21 and a driver qualification card.

Licence validity

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.

Driver CPC

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

Tyre tread depth

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

Air brake check

Before driving, check that air pressure builds up and does not leak down with the engine off; a pressure drop indicates a leak.

Tachograph calibration

The tachograph must be calibrated every two years and its seals must be intact; tampering is an offence.

Maximum vehicle height

The maximum height for a vehicle is 4 m; loads exceeding this require a special permit.

Maximum rigid length

The maximum length for a rigid lorry is 12 m; a road train may be up to 18.75 m.

Load projection marking

A load projecting more than 1 m to the rear must be marked with a warning flag; at night it must carry a red light and reflector.

Daily driving limit

Daily driving time may not exceed 9 hours, extendable to 10 hours twice a week; the weekly limit is 56 hours.

Four and a half hour rule

After 4.5 hours of driving a break of at least 45 minutes is required, which may be split into 15 minutes plus 30 minutes.

Daily rest period

Daily rest is 11 hours, reducible to 9 hours three times between weekly rests; a weekly rest is 45 hours, reducible to 24.

Driver card

The digital tachograph driver card is personal and must not be shared; it must be inserted at the start of the shift and removed at the end.

CMR consignment note

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

Records to carry

The driver must carry the driver card, the previous 28 days of records, the vehicle documents and, where required, the CMR note.

Emergency number

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

Recovery position

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

Adult CPR ratio

Adult CPR uses 30 chest compressions to 2 rescue breaths at 100–120 per minute with a compression depth of 5–6 cm.

Fuel-efficient speed

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

Tyre pressure and fuel

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