Question 1Traffic rules and road signs

What does a red circular sign with a white horizontal bar in the middle mean?

  1. One-way traffic ahead
  2. End of all restrictions
  3. No entry for vehicles Correct answer.
  4. Stop and give way

Explanation

A red circle with a white horizontal bar is the no-entry sign, which forbids vehicles from entering that road from the direction in which the sign faces. It differs from the stop sign, which is an octagon and requires a full stop. Drivers must find another route rather than proceed past this sign.

Question 2Traffic rules and road signs

A triangular warning sign with a red border shows a pedestrian on a crossing. What should the driver expect?

  1. A pedestrian crossing ahead where people may step onto the road Correct answer.
  2. A school building entrance with no road crossing
  3. A path reserved only for cyclists
  4. A zone where pedestrians are forbidden

Explanation

Red-bordered triangles are warning signs that alert drivers to a hazard ahead. A pedestrian symbol inside the triangle warns of a marked pedestrian crossing, so the driver should reduce speed and be ready to stop. Warning signs do not forbid anything; they prepare the driver to react.

Question 3Traffic rules and road signs

What is the general speed limit for passenger cars on a motorway in Bulgaria when no other limit is posted?

  1. 140 km/h Correct answer.
  2. 120 km/h
  3. 90 km/h
  4. 130 km/h

Explanation

On Bulgarian motorways the default maximum speed for passenger cars is 140 km/h. Lower limits apply on roads outside built-up areas and inside settlements. Posted signs always take priority over the general default, so drivers must watch for local restrictions.

Question 4Traffic rules and road signs

Unless otherwise signed, what is the maximum speed for passenger cars in a built-up area in Bulgaria?

  1. 60 km/h
  2. 50 km/h Correct answer.
  3. 40 km/h
  4. 70 km/h

Explanation

Inside settlements the general maximum speed for cars is 50 km/h unless signs indicate otherwise. This lower limit reflects the presence of pedestrians, cyclists and junctions. Drivers must still slow below the limit when conditions require it.

Question 5Traffic rules and road signs

You approach a junction where a traffic light shows a flashing yellow signal. How should you proceed?

  1. Accelerate to clear the junction before the light changes
  2. Stop completely and wait for a green light
  3. Continue with caution, obeying the priority rules and any signs Correct answer.
  4. Treat the junction as closed and turn back

Explanation

A flashing yellow light means the signals are not controlling priority at that moment. Drivers must proceed carefully and apply the normal right-of-way rules, including any priority signs or road markings. It is not a stop command, but caution is required.

Question 6Traffic rules and road signs

At an unmarked intersection of two equally important roads, which vehicle has priority?

  1. The vehicle approaching from the left
  2. The faster vehicle
  3. The vehicle approaching from the right Correct answer.
  4. The larger vehicle

Explanation

When no signs or signals establish priority, the general rule gives way to traffic coming from the right. This rule applies at intersections of roads of equal importance. Drivers should slow down and be prepared to yield to any vehicle on their right.

Question 7Traffic rules and road signs

What does a solid white line along the centre of the road indicate?

  1. The road has one lane only
  2. Overtaking is always allowed
  3. Parking is permitted on the line
  4. Crossing it is prohibited Correct answer.

Explanation

A continuous white centre line marks a boundary that drivers must not cross. It is used where visibility or road layout makes overtaking unsafe. A broken line, by contrast, may be crossed when it is safe to do so.

Question 8Traffic rules and road signs

A driver intends to turn left at a junction. Which action is correct?

  1. Signal only after starting the turn
  2. Signal early, move to the left position and give way to oncoming traffic Correct answer.
  3. Stay in the right lane and turn sharply across
  4. Turn without signalling if no car is visible

Explanation

Before turning left the driver must signal in good time, position the vehicle correctly and yield to oncoming traffic that has priority. Signalling late or not at all deprives others of warning. The turn must be made smoothly without cutting across other lanes.

Question 9Traffic rules and road signs

When are you permitted to use a mobile phone held in your hand while driving?

  1. While waiting at a red light
  2. While driving slowly in a traffic jam
  3. While overtaking on a motorway
  4. Never, unless the vehicle is safely stopped Correct answer.

Explanation

Holding and using a mobile phone while driving is prohibited because it distracts the driver from the road. The prohibition applies even when the car is temporarily stationary in traffic. A hands-free system may be used where permitted, but the phone itself must not be held.

Question 10Traffic rules and road signs

What is the maximum permitted blood alcohol concentration for drivers in Bulgaria?

  1. 0.10 percent
  2. 0.00 percent
  3. 0.08 percent
  4. 0.05 percent Correct answer.

Explanation

Bulgarian law sets the general limit at a blood alcohol concentration of 0.05 percent, which is 0.5 per mille. Novice and professional drivers face stricter rules. Any alcohol impairs judgement, so the safest approach is not to drink before driving.

Question 11Traffic rules and road signs

How far before a pedestrian crossing must a driver begin to slow down and prepare to stop?

  1. Only after a pedestrian has already stepped onto the crossing
  2. Exactly at the crossing line
  3. Early enough that the vehicle can stop safely if someone steps out Correct answer.
  4. No preparation is needed if the crossing looks empty

Explanation

Drivers must approach a pedestrian crossing at a speed that allows them to stop if a pedestrian appears. Preparation should begin well before the crossing, not at the last moment. An apparently empty crossing may still hide a person about to step out.

Question 12Traffic rules and road signs

What does a blue square sign with a white 'P' indicate?

  1. A no-parking zone
  2. A parking place Correct answer.
  3. A police checkpoint
  4. A pedestrian zone

Explanation

A blue square with a white letter P marks a place where parking is permitted. Additional plates may restrict duration or vehicle type. A prohibition on parking would instead be shown by a circular red-bordered sign.

Question 13Traffic rules and road signs

You are driving and an emergency vehicle with flashing blue lights and siren approaches from behind. What should you do?

  1. Give way by slowing and moving aside where it is safe Correct answer.
  2. Ignore it if you are below the speed limit
  3. Stop immediately in your lane
  4. Speed up to stay ahead of it

Explanation

Emergency vehicles on urgent duty have priority, and other drivers must clear a path. The correct response is to slow down and move to the side when it is safe, without endangering others. Blocking the route delays help and may be an offence.

Question 14Traffic rules and road signs

What is the purpose of a safety distance between your vehicle and the one ahead?

  1. To allow enough time to stop if the vehicle ahead brakes suddenly Correct answer.
  2. To keep the engine at a steady temperature
  3. To let other cars overtake into the gap
  4. To reduce fuel consumption only

Explanation

A safe following distance provides the reaction and braking time needed to stop if the vehicle ahead slows suddenly. The gap should increase with speed and in poor weather. Tailgating removes this margin and greatly raises collision risk.

Question 15Traffic rules and road signs

When may you overtake another vehicle on the right?

  1. When the vehicle ahead is signalling and turning left, if there is room Correct answer.
  2. Only when the vehicle ahead is a truck
  3. Whenever the road ahead is clear
  4. Whenever you are driving on a motorway

Explanation

Overtaking on the right is generally prohibited, but an exception exists when the vehicle ahead is turning left and there is sufficient space to pass safely. In all other cases overtaking must be done on the left. Passing on the right in normal traffic is dangerous and unlawful.

Question 16Traffic rules and road signs

What should a driver do when a traffic light turns green but the junction ahead is blocked by queuing traffic?

  1. Enter the junction and stop in the middle
  2. Drive onto the pavement to pass
  3. Sound the horn until traffic moves
  4. Wait before the junction until there is space to clear it Correct answer.

Explanation

A green light permits movement but does not entitle a driver to block the junction. If traffic is queued beyond the junction, the driver should wait until there is space to cross completely. Entering and stopping inside the junction obstructs cross traffic and pedestrians.

Question 17Traffic rules and road signs

A sign shows a red circle containing a black number 50. What does it mean?

  1. Only vehicles over 50 years old may pass
  2. The road is 50 metres ahead
  3. Minimum speed is 50 km/h
  4. Maximum speed is 50 km/h Correct answer.

Explanation

A red circular sign with a number sets the maximum permitted speed in kilometres per hour. The red border indicates a prohibition, so exceeding 50 km/h is forbidden. A minimum speed would be shown on a blue circular sign.

Question 18Traffic rules and road signs

When driving at night, when must you switch from high beam to dipped headlights?

  1. Only when entering a tunnel
  2. When meeting oncoming traffic or following another vehicle closely Correct answer.
  3. Only when it starts to rain
  4. Never, because high beam gives the best view

Explanation

High beam can dazzle oncoming drivers and those ahead through their mirrors. The law requires switching to dipped headlights when meeting traffic or following closely. Dipped beam still illuminates the road without blinding others.

Question 19Traffic rules and road signs

What does a broken white line between lanes of traffic in the same direction mean?

  1. The lane ends immediately
  2. Lane changes are prohibited
  3. Lane changes are permitted when it is safe Correct answer.
  4. Only buses may use the left lane

Explanation

A broken line marks a lane boundary that may be crossed when it is safe to change lanes. Drivers must still signal and check mirrors and blind spots. A solid line in the same position would forbid crossing.

Question 20Traffic rules and road signs

You are involved in a road traffic collision with only minor damage and no injuries. What is the correct action?

  1. Leave the scene immediately without stopping
  2. Wait in the traffic lane until the police arrive
  3. Move vehicles to a safe place if possible and exchange details Correct answer.
  4. Drive away and report it only the next day

Explanation

After a minor collision with no injuries, drivers should secure the scene, move vehicles out of the traffic flow if they can, and exchange insurance and contact details. Leaving without stopping is an offence. Blocking the road unnecessarily creates further danger.

Question 21Traffic rules and road signs

What does a triangular sign showing a narrowing road warn the driver about?

  1. The road ends ahead
  2. The carriageway ahead becomes narrower Correct answer.
  3. A toll booth is ahead
  4. The speed limit increases

Explanation

A warning triangle with a narrowing symbol tells drivers that the carriageway will reduce in width ahead. They should slow down and adjust their position to avoid squeezing other road users. The sign warns of a hazard rather than imposing a prohibition.

Question 22Traffic rules and road signs

In which situation must you give way to a tram at an intersection?

  1. Only when you are turning right
  2. When the tram is approaching on rails and the signs do not give you priority Correct answer.
  3. Only when the tram is stationary
  4. Never, because trams must always yield

Explanation

Trams generally have priority at intersections unless signs or signals indicate otherwise. Drivers must yield to an approaching tram, which cannot steer around obstacles and needs a long distance to stop. Ignoring this rule can cause severe collisions.

Question 23Traffic rules and road signs

What is the correct use of a seat belt for the driver and passengers?

  1. Only the driver must wear one
  2. It must be worn by all occupants where belts are fitted Correct answer.
  3. Only front-seat passengers must wear one
  4. It is optional on short trips

Explanation

Seat belts must be worn by the driver and all passengers for whom belts are provided. The requirement applies regardless of trip length or seat position. Belts greatly reduce the risk of serious injury in a collision.

Question 24Traffic rules and road signs

A driver is about to enter a roundabout and sees a 'give way' line. What is the correct procedure?

  1. Drive around the roundabout in either direction
  2. Yield to traffic already on the roundabout and enter when there is a safe gap Correct answer.
  3. Stop fully and wait for a green light
  4. Enter immediately because traffic on the roundabout must stop

Explanation

At a roundabout controlled by give-way markings, entering traffic must yield to vehicles already circulating. The driver should choose a safe gap and enter without forcing others to brake. Traffic on the roundabout normally travels in one direction only.

Question 25Traffic rules and road signs

When is a driver allowed to use the horn in a built-up area?

  1. Only to warn of an immediate danger Correct answer.
  2. At any time to greet other drivers
  3. To signal that a light has turned green
  4. Whenever traffic is slow

Explanation

In built-up areas the horn may be used only to warn of an imminent danger, not for greeting or impatience. Unnecessary horn use causes noise nuisance and may be fined. The horn is a warning device, not a means of communication.

Question 26Traffic rules and road signs

What does a red triangular sign with a picture of children warn a driver about?

  1. A pedestrian zone beginning at the sign
  2. Children likely to be crossing or near the road Correct answer.
  3. A playground where parking is forbidden
  4. A school bus stop ahead

Explanation

Triangular signs with a red border are warning signs. The children symbol warns that a school, playground or similar area is nearby, so children may step onto the carriageway unexpectedly. The driver should reduce speed and be ready to stop.

Question 27Traffic rules and road signs

What does a circular sign with a red border and a white horizontal bar on a red background mean?

  1. No parking
  2. End of a restriction
  3. Stop and give way
  4. No entry for vehicles Correct answer.

Explanation

A red circle with a white horizontal bar is the 'no entry' sign. It prohibits all vehicles from entering that road from the direction faced. It is not a stop sign and does not merely end a restriction.

Question 28Traffic rules and road signs

What does a yellow diamond-shaped sign with a white border indicate?

  1. A temporary roadworks zone
  2. A zone where overtaking is prohibited
  3. A compulsory direction of travel
  4. A priority road on which traffic has right of way at junctions Correct answer.

Explanation

The yellow diamond marks a priority road. Traffic on this road has right of way at intersections over traffic joining from side roads, until a sign cancels the priority. It does not by itself impose a speed or overtaking restriction.

Question 29Traffic rules and road signs

A driver approaches a junction where a police officer stands with an arm raised vertically. What must the driver do?

  1. Sound the horn and proceed slowly
  2. Continue if the light is green
  3. Turn only to the right
  4. Stop before the junction Correct answer.

Explanation

An officer's signals override traffic lights and signs. A raised arm means traffic must stop. The driver must halt and wait until the officer gives a signal to proceed.

Question 30Traffic rules and road signs

What does a flashing amber light at a pedestrian crossing require a driver to do?

  1. Proceed only if no pedestrians are on the crossing, giving way to any who are Correct answer.
  2. Stop completely until the light turns green
  3. Treat it exactly as a red light
  4. Speed up to clear the crossing quickly

Explanation

A flashing amber signal means drivers may proceed but must give way to pedestrians already on or entering the crossing. It is a yield requirement rather than an absolute stop.

Question 31Traffic rules and road signs

On a road with a single broken white line at the centre, when may a driver cross it to overtake?

  1. Only when it is safe and the manoeuvre is permitted Correct answer.
  2. Never, under any circumstances
  3. Only during daylight hours
  4. Only if the vehicle ahead is a lorry

Explanation

A single broken centre line may be crossed for overtaking or turning when visibility and traffic conditions make it safe. The line is advisory rather than an absolute barrier.

Question 32Traffic rules and road signs

What does a continuous solid line together with a broken line on the driver's side mean?

  1. Overtaking is allowed for all traffic
  2. Parking is permitted along the line
  3. The road has become a one-way street
  4. Overtaking is allowed for traffic on the side with the broken line Correct answer.

Explanation

When a solid and a broken line run together, the line nearest the driver governs. Traffic on the side of the broken line may cross when safe, while traffic on the side of the solid line may not.

Question 33Traffic rules and road signs

What is the meaning of a sign showing a red circle with a white arrow pointing straight ahead crossed by a red diagonal line?

  1. Compulsory direction straight ahead
  2. End of a one-way street
  3. No straight-ahead movement permitted Correct answer.
  4. One-way traffic ahead

Explanation

A blue circle with a white arrow gives a compulsory direction. When the arrow is crossed by a red diagonal line, going straight ahead is prohibited. Drivers must turn instead.

Question 34Traffic rules and road signs

A driver wishes to turn right into a road and sees a 'no right turn' sign. What is the correct action?

  1. Ignore the sign if the road is empty
  2. Turn right after stopping completely
  3. Turn right if no traffic is approaching
  4. Continue to a permitted route and turn elsewhere Correct answer.

Explanation

A prohibition sign applies regardless of traffic conditions. The driver must not turn right at that point and should continue until a legal route allows the intended direction.

Question 35Traffic rules and road signs

How should a driver respond to a 'give way' sign at a junction with limited visibility?

  1. Sound the horn and proceed
  2. Flash headlights and continue
  3. Maintain speed and rely on the other drivers
  4. Slow down or stop so as to be able to yield to traffic on the priority road Correct answer.

Explanation

The give way sign requires the driver to yield to traffic on the road being joined. Where visibility is poor, the driver must slow or stop so as to be able to give way safely.

Question 36Traffic rules and road signs

What does a rectangular blue sign with a white bicycle symbol indicate?

  1. A cycle repair shop
  2. Cyclists are prohibited
  3. Cyclists must give way to all traffic
  4. A route or lane designated for cyclists Correct answer.

Explanation

A blue rectangular sign with a bicycle shows a route or lane intended for cyclists. It informs drivers that cyclists are expected there and that they should be given space.

Question 37Traffic rules and road signs

What does a sign with a red circle containing a black lorry and a red diagonal line mean?

  1. Goods vehicles above a stated mass are prohibited Correct answer.
  2. Lorries only may use the road
  3. Lorries must reduce speed
  4. A lorry park is ahead

Explanation

A red circle with a vehicle symbol crossed by a diagonal line prohibits that class of vehicle. When a mass is shown, the ban applies to goods vehicles exceeding that mass.

Question 38Traffic rules and road signs

A driver sees a 'slippery road' warning sign while it is raining. What is the appropriate response?

  1. Reduce speed, avoid sudden braking and increase the following distance Correct answer.
  2. Switch on high beam headlights
  3. Accelerate to pass the wet section quickly
  4. Keep the same speed but brake harder in bends

Explanation

The warning indicates reduced grip, which rain makes worse. The driver should slow down, make smooth inputs and leave a larger gap so there is time to stop.

Question 39Traffic rules and road signs

When may a driver pass a stationary tram that has stopped at a designated stop without a refuge island?

  1. Only with great care, giving way to passengers boarding or alighting Correct answer.
  2. At normal speed on the left
  3. Only after sounding the horn
  4. Never, until the tram moves off

Explanation

Passengers may step onto the carriageway to reach a tram stop without a refuge. The driver must pass slowly and give way to people boarding or leaving the tram.

Question 40Traffic rules and road signs

What is the correct behaviour when a bus is signalling to leave a bus stop in a built-up area?

  1. Sound the horn to warn the bus
  2. Pass on the left regardless of oncoming traffic
  3. Accelerate to pass before it moves
  4. Give way where it is safe to do so Correct answer.

Explanation

In built-up areas drivers should allow buses to rejoin the traffic flow when it is safe. Forcing a bus to wait disrupts the flow and increases risk.

Question 41Traffic rules and road signs

What is the correct way to use a lane marked with a white bicycle symbol on the road surface?

  1. Motor vehicles must not drive or park in it Correct answer.
  2. Motor vehicles may stop in it for short deliveries
  3. It may be used for overtaking when convenient
  4. It applies only at night

Explanation

A marked cycle lane is reserved for cyclists. Motor vehicles must keep out of it, both for driving and for parking, unless a sign expressly permits otherwise.

Question 42Traffic rules and road signs

A driver approaches a level crossing with a barrier that is raised and a red light that begins to flash. What must the driver do?

  1. Stop before the crossing and wait Correct answer.
  2. Cross quickly before the barrier lowers
  3. Proceed if the barrier is still up
  4. Sound the horn and continue

Explanation

Flashing red lights at a level crossing mean a train is approaching and the driver must stop. The barrier may not yet have begun to move, but the light alone is the signal to halt.

Question 43Traffic rules and road signs

What does a sign showing a red circle with the number 3.5 and a lorry symbol mean?

  1. Minimum speed for lorries is 3.5 km/h
  2. Lorries must keep 3.5 metres apart
  3. Vehicles over 3.5 tonnes are prohibited Correct answer.
  4. The road is 3.5 metres wide

Explanation

A red circle with a vehicle symbol and a mass figure prohibits vehicles exceeding that mass. In this case goods vehicles above 3.5 tonnes may not enter.

Question 44Traffic rules and road signs

When driving in fog, which lights should be used?

  1. High beam headlights
  2. Hazard warning lights while moving
  3. Dipped headlights and fog lights where fitted Correct answer.
  4. Side lights only

Explanation

Dipped headlights and fog lights improve visibility without reflecting glare back at the driver. High beam in fog scatters light and reduces the view ahead.

Question 45Traffic rules and road signs

What is the rule on using hazard warning lights while the vehicle is moving?

  1. They may be used to warn of a sudden hazard such as a queue ahead Correct answer.
  2. They may replace indicators when turning
  3. They may be used to indicate an intention to park
  4. They may be used whenever it is raining

Explanation

Hazard warning lights are intended to warn others of a hazard, such as an obstruction or a sudden queue. They are not a substitute for indicators or a general rain light.

Question 46Traffic rules and road signs

A driver must park on a road at night outside a built-up area. What is required?

  1. High beam must be left on
  2. No lights are needed if the vehicle is off the carriageway
  3. Parking lights must be left on so the vehicle is visible Correct answer.
  4. Hazard lights must flash all night

Explanation

Outside built-up areas at night a parked vehicle must be made visible to other road users. Parking lights serve this purpose where the vehicle is on or near the carriageway.

Question 47Traffic rules and road signs

What does a yellow zigzag line marked on the road near a school entrance mean?

  1. The area is reserved for delivery vehicles
  2. Parking is allowed for a short time
  3. Stopping and parking are prohibited in the marked area Correct answer.
  4. Only buses may stop there

Explanation

A yellow zigzag marking outside a school protects sight lines and pedestrian access. Drivers must not stop or park on it, even briefly.

Question 48Traffic rules and road signs

A driver is following a large lorry that obscures the view ahead. What is the safest action?

  1. Overtake immediately on a bend
  2. Follow closely so no one can cut in
  3. Drop back to increase the view and the stopping distance Correct answer.
  4. Flash headlights to make the lorry move faster

Explanation

A large vehicle blocks the view of the road ahead. Increasing the gap restores visibility and provides the distance needed to stop if the lorry brakes suddenly.

Question 49Traffic rules and road signs

What is required before a driver may reverse into a side road?

  1. The horn must be sounded continuously
  2. Nothing, provided the vehicle is moving slowly
  3. A passenger must always guide the driver
  4. The driver must ensure the way is clear and that reversing is not prohibited Correct answer.

Explanation

Reversing is permitted only where it is safe and not prohibited by signs or markings. The driver must check carefully for pedestrians and other traffic before and during the manoeuvre.

Question 50Traffic rules and road signs

What is the correct action when an oncoming vehicle at night fails to dip its headlights?

  1. Brake sharply and stop in the lane
  2. Switch on high beam in return
  3. Look towards the left edge of your lane and slow down if necessary Correct answer.
  4. Close your eyes briefly until it passes

Explanation

Looking towards the left edge avoids the glare while keeping the vehicle in lane. Reducing speed gives more time to react until the other driver has passed.
