Question 1Road signs and markings

What does a round road sign with a red border and a white centre generally indicate?

  1. A prohibition or restriction applying to traffic Correct answer.
  2. A warning of a hazard ahead
  3. An instruction to follow a mandatory direction
  4. A service facility available nearby

Explanation

In Bulgaria, circular signs with a red rim are regulatory prohibitory signs. They impose a ban or limit, such as a speed restriction or a no-entry rule for the class of road user shown. Warning signs are triangular with a red border, and mandatory signs are blue circles.

Question 2Road signs and markings

A triangular sign with a red border shows a symbol of a bend. What is the driver required to do?

  1. Sound the horn before reaching the bend
  2. Maintain speed because the sign only informs about road layout
  3. Reduce speed and prepare for a curve in the road ahead Correct answer.
  4. Stop completely before entering the curve

Explanation

Triangular red-bordered signs warn of a hazard ahead, here a curve. The correct response is to slow down and adjust driving to the geometry of the road so the vehicle stays in lane. The sign does not order a stop or a horn signal.

Question 3Road signs and markings

What is the meaning of a solid white line running along the centre of the carriageway?

  1. The line marks a bus lane boundary only
  2. Overtaking is permitted if the road is clear
  3. The line marks the edge of a parking zone
  4. Overtaking across the line is prohibited Correct answer.

Explanation

A continuous longitudinal line separates traffic streams and must not be crossed. It is placed where visibility or road layout makes overtaking unsafe. A broken line, by contrast, may be crossed when it is safe to do so.

Question 4Road signs and markings

What does a blue circular sign with a white arrow pointing straight ahead mean?

  1. The road ahead is a one-way street in the opposite direction
  2. Traffic must proceed only in the direction of the arrow Correct answer.
  3. Traffic may turn left or right freely
  4. A compulsory stop lies ahead

Explanation

Blue circular signs give mandatory instructions. A white arrow on a blue background requires road users to follow the indicated direction. Deviating from that direction is an offence at that location.

Question 5Road signs and markings

Which sign warns that a pedestrian crossing is ahead?

  1. A blue square sign showing a bus
  2. A triangular sign showing a person walking on a striped crossing Correct answer.
  3. A yellow diamond showing a crossroad
  4. A red circle with a white horizontal bar

Explanation

Warning signs for pedestrian crossings use a triangle with a red border and a figure walking over zebra stripes. Drivers must expect pedestrians and be ready to give way. The other shapes belong to different sign families.

Question 6Road signs and markings

A driver sees a STOP sign at a junction with no other traffic. What must the driver do?

  1. Slow down and continue if the junction looks clear
  2. Stop only if another vehicle is approaching
  3. Come to a complete stop at the stop line and then proceed when safe Correct answer.
  4. Sound the horn and continue without stopping

Explanation

The STOP sign requires a full halt at the marked line regardless of whether traffic is visible. After stopping, the driver gives way and may proceed only when the way is clear. Rolling slowly through the junction does not satisfy the rule.

Question 7Road signs and markings

What is the purpose of a broken white line between lanes on a multi-lane road?

  1. It separates lanes and may be crossed when it is safe Correct answer.
  2. It reserves the lane for emergency vehicles
  3. It marks the outer edge of the carriageway
  4. It forbids any lane change at all times

Explanation

Broken lines divide lanes and may be crossed for a lane change or overtaking when the manoeuvre is safe. They guide drivers to keep within a lane. Continuous lines, in contrast, must not be crossed.

Question 8Road signs and markings

What does a sign showing a red circle with a white horizontal bar mean?

  1. Entry is prohibited for vehicles Correct answer.
  2. Parking is allowed beyond the sign
  3. A pedestrian zone begins
  4. A speed limit applies

Explanation

The red circle with a white bar is the no-entry sign. It forbids vehicles from entering the road or area in the direction faced. Drivers must find another route rather than pass the sign.

Question 9Road signs and markings

A driver approaches a junction where a yellow diamond sign is displayed on the priority road. What does this mean?

  1. The driver on this road has priority over traffic from side roads Correct answer.
  2. The driver must give way to all traffic from the right
  3. The driver must leave the priority road immediately
  4. The driver must stop before the junction

Explanation

The yellow diamond marks a priority road, meaning traffic on it has right of way over vehicles joining from side roads. Drivers should still approach with care because other users may misjudge priority. The sign does not remove the duty to avoid collisions.

Question 10Road signs and markings

What is indicated by a continuous yellow line along the kerb?

  1. The kerb marks a cycle lane
  2. Loading is permitted at all hours
  3. Stopping and parking are prohibited along that stretch Correct answer.
  4. Parking is free for a limited time

Explanation

A continuous yellow line at the kerb means stopping and parking are not allowed there. It is used where parked vehicles would obstruct traffic or endanger road users. A broken yellow line allows limited stopping or parking under stated conditions.

Question 11Road signs and markings

A driver sees a triangular sign with a red border showing an exclamation mark. How should the driver respond?

  1. Accelerate to clear the area quickly
  2. Ignore it because it carries no specific meaning
  3. Stop immediately and wait for assistance
  4. Be alert for an unspecified hazard and reduce speed Correct answer.

Explanation

The exclamation mark warning sign alerts drivers to a hazard that is not covered by a more specific symbol. The correct response is heightened caution and a lower speed. The sign requires attention rather than a stop.

Question 12Road signs and markings

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

  1. Passing is prohibited
  2. A parking place is available Correct answer.
  3. A pedestrian zone begins
  4. A police checkpoint is ahead

Explanation

The white letter P on a blue background is the international parking sign. It shows that parking is permitted in the designated area, subject to any supplementary plates. Supplementary signs may limit duration or restrict who may park.

Question 13Road signs and markings

A driver is in a lane marked with a white bicycle symbol. What does this mean?

  1. The lane is for overtaking only
  2. The lane is reserved for cyclists and other traffic must keep out Correct answer.
  3. Cyclists must dismount and walk in this lane
  4. The lane is a parking area for motorcycles

Explanation

A lane marked with a bicycle symbol is a cycle lane reserved for bicycles. Other vehicles must not use it, except where specific rules allow crossing to reach a junction or property. Entering it otherwise obstructs cyclists and is an offence.

Question 14Road signs and markings

A driver approaches a junction and sees a 'Give Way' sign together with a broken white line across the entry. What is required?

  1. Yield to traffic on the priority road and cross only when it is safe Correct answer.
  2. Stop completely for at least three seconds
  3. Proceed without looking because the line is broken
  4. Wait for a green signal before moving

Explanation

The give-way sign and broken line require the driver to yield to traffic on the road being entered. A full stop is not compulsory if the way is clearly safe, but the driver must be able to stop if necessary. Priority traffic must not be forced to brake.

Question 15Road signs and markings

What does a red circle containing the number 50 mean?

  1. A toll of 50 units applies
  2. The minimum permitted speed is 50 km/h
  3. The road is 50 metres ahead
  4. The maximum permitted speed is 50 km/h Correct answer.

Explanation

A number inside a red circle sets the maximum speed allowed from that point. The limit applies until a different limit or an end-of-restriction sign appears. Exceeding it is an offence regardless of traffic conditions.

Question 16Road signs and markings

A driver sees a sign showing two cars side by side, one red and one black, inside a red circle. What does it prohibit?

  1. Entering a residential area
  2. Parking on the carriageway
  3. Driving above 60 km/h
  4. Overtaking other motor vehicles Correct answer.

Explanation

The red circle with two cars indicates a ban on overtaking motor vehicles other than two-wheeled machines without sidecars. The restriction applies from the sign until it is cancelled. It exists where overtaking would be especially dangerous.

Question 17Road signs and markings

What is the meaning of a white arrow painted on the road surface pointing left in a lane?

  1. Vehicles in that lane must turn left Correct answer.
  2. Vehicles in that lane may turn left or continue straight
  3. The lane ends and merges left
  4. The lane is reserved for buses turning left

Explanation

Direction arrows painted in a lane prescribe the movement for vehicles in that lane. A left-pointing arrow means the lane is for turning left at the junction ahead. Drivers who wish to go straight should use a lane marked accordingly.

Question 18Road signs and markings

A driver sees a triangular sign with a red border showing a traffic signal. What should the driver expect?

  1. A motorway start
  2. A railway crossing without barriers
  3. Traffic lights ahead that may not be visible in time Correct answer.
  4. A tunnel entrance

Explanation

The signal warning sign alerts drivers that traffic lights are ahead, often where they are hard to see in advance. Drivers should reduce speed and prepare to obey the lights. It does not mean the lights are out of order.

Question 19Road signs and markings

A driver sees a square blue sign showing a white symbol of a telephone. What does it indicate?

  1. A radio frequency must be used
  2. A telephone facility is available nearby Correct answer.
  3. A police emergency post is staffed
  4. Telephone use while driving is permitted

Explanation

Blue square signs with service symbols inform drivers of facilities available in the area. The telephone symbol points to a public telephone nearby. It does not change the legal rules on using a phone while driving.

Question 20Road signs and markings

A driver approaches a junction where the centre line changes from broken to continuous just before the junction. What is the correct interpretation?

  1. Overtaking must not be started or continued across the continuous section Correct answer.
  2. The line marks a parking restriction
  3. Overtaking is allowed because the line was broken earlier
  4. The continuous line applies only to heavy vehicles

Explanation

A continuous line near a junction is placed there to prevent overtaking where conflicts are likely. Once the line becomes continuous, drivers must not cross it to overtake. Any overtaking manoeuvre must be completed before reaching it.

Question 21Road signs and markings

A driver sees a sign with a red border showing a pedestrian symbol crossed by a red diagonal line. What does it mean?

  1. Pedestrians have priority over vehicles
  2. A school zone begins
  3. A pedestrian crossing is ahead
  4. Pedestrians are prohibited from this road Correct answer.

Explanation

A red diagonal line across a symbol cancels or prohibits the activity shown. With a pedestrian symbol, it means pedestrians may not use that road, typically a motorway or similar restricted route. Warning of a crossing uses a triangle without the diagonal bar.

Question 22Road signs and markings

A driver sees a broken yellow line along the kerb. How does this differ from a continuous yellow line?

  1. A broken yellow line bans all stopping at all times
  2. A broken yellow line marks a loading bay for lorries only
  3. A broken yellow line permits limited stopping or parking where allowed Correct answer.
  4. A broken yellow line indicates a bus stop

Explanation

Kerb markings use yellow lines to control stopping and parking. A continuous line bans stopping and parking, while a broken line allows stopping or parking subject to any signs. Drivers must check nearby plates for time limits or exceptions.

Question 23Road signs and markings

A driver sees a triangular sign with a red border showing a steep descent percentage. What is the safest response?

  1. Select a lower gear and control speed before the descent begins Correct answer.
  2. Apply the brakes continuously throughout the descent
  3. Accelerate to maintain momentum down the slope
  4. Shift to neutral to save fuel on the slope

Explanation

A steep descent warning tells drivers that engine braking will be needed to control speed. Selecting a lower gear before the slope reduces reliance on the brakes and prevents overheating. Continuous braking or coasting in neutral is unsafe.

Question 24Road signs and markings

A driver sees a lane marked with the word 'BUS' and a solid white boundary line. When may a private car enter this lane?

  1. At any time outside peak hours without restriction
  2. Whenever traffic in the other lanes is heavy
  3. Only where signs or markings specifically permit crossing, such as to reach a turn Correct answer.
  4. Never, under any circumstances

Explanation

Bus lanes are reserved for buses and other authorised vehicles during the times shown. Other vehicles may cross the boundary only where signs or markings allow, for example to make a permitted turn. Entering otherwise is an offence.

Question 25Road signs and markings

A driver sees a sign showing a white arrow bending to the right on a blue circle. What does it require?

  1. Traffic must give way to the right
  2. Traffic must turn right at the next junction
  3. Traffic must pass to the right of the obstacle or island Correct answer.
  4. Traffic must stop on the right side

Explanation

A blue circular sign with a bending arrow directs traffic to keep to the side shown, often around an obstacle or traffic island. It is a mandatory instruction, not a warning. Drivers must follow the indicated path.

Question 26Road signs and markings

A driver sees a circular sign with a red border containing a white arrow pointing straight ahead on a blue background. What does this sign require?

  1. Give way to traffic from the right
  2. Stop and wait for oncoming traffic
  3. Turn back because the road is closed
  4. Proceed only in the direction shown by the arrow Correct answer.

Explanation

A blue circular sign with a white arrow is a mandatory direction sign. It orders drivers to travel only in the direction the arrow indicates, so going straight is the only permitted movement at that point. Ignoring it is a traffic violation even when the road appears clear.

Question 27Road signs and markings

What does a triangular sign with a red border showing a symbol of two children indicate?

  1. A playground closed to traffic
  2. A school bus stop ahead
  3. Children crossing or a school zone ahead Correct answer.
  4. A pedestrian zone begins here

Explanation

Red-bordered triangles are warning signs. The children symbol warns that a school, kindergarten or place where children cross is ahead, so the driver should slow down and be ready to stop. The sign warns of a hazard rather than imposing a ban.

Question 28Road signs and markings

A driver sees a white line made of long dashes with short gaps separating two lanes travelling in the same direction. What does this line mean?

  1. The lane on the right is reserved for buses
  2. Crossing is forbidden at all times
  3. The road narrows to a single lane ahead
  4. Lane changing is permitted when it is safe Correct answer.

Explanation

A broken white line between lanes of the same direction may be crossed. Drivers may change lanes when they have checked mirrors and blind spots and it is safe to do so. The line does not reserve either lane for a particular class of vehicle.

Question 29Road signs and markings

A driver sees a round sign with a red border containing the number 3.5 with a truck symbol above it. What does this sign prohibit?

  1. All vehicles from exceeding 3.5 metres in height
  2. Traffic from following closer than 3.5 metres
  3. Goods vehicles over 3.5 tonnes from proceeding Correct answer.
  4. Vehicles wider than 3.5 metres from entering

Explanation

A red-bordered circle with a mass figure and a lorry symbol is a prohibition on goods vehicles exceeding that maximum permitted mass. The figure refers to the vehicle's weight, not its dimensions or following distance. Other signs use arrows or width figures to show height and width limits.

Question 30Road signs and markings

A driver approaches a junction where the road surface shows a large white triangle pointing towards the driver, painted across the lane. What does this marking require?

  1. Stop completely before the marking
  2. Sound the horn before continuing
  3. Give way to traffic on the crossing road Correct answer.
  4. Accelerate to clear the junction quickly

Explanation

A large white triangle painted across the approach lane is the give-way marking. It tells the driver to yield to traffic on the road being entered and to proceed only when it is clear. It does not require a full stop when nothing is coming.

Question 31Road signs and markings

A driver sees a rectangular sign with a blue background showing a white symbol of a bed. What does this sign indicate?

  1. A hospital with emergency care
  2. A compulsory rest stop for lorries
  3. Accommodation is available nearby Correct answer.
  4. A camping area for tents only

Explanation

Blue rectangular signs provide information or services. The bed symbol means that accommodation such as a hotel or motel is available at or near that point. It does not impose any obligation on the driver.

Question 32Road signs and markings

A driver sees a sign with a red border showing a black car inside a red circle with a red diagonal line through it. What does this sign mean?

  1. Cars must keep to the left lane
  2. Motor vehicles are prohibited from proceeding Correct answer.
  3. Cars must use dipped headlights
  4. Parking of cars is prohibited

Explanation

A red circle with a diagonal line over a vehicle symbol is a prohibition sign. It bans the class of vehicle shown from continuing past the sign. The diagonal line distinguishes a ban from a mandatory instruction.

Question 33Road signs and markings

A driver is travelling on a road where the centre line consists of a continuous line on the driver's side and a broken line on the other side. What does this allow?

  1. Both directions may cross freely
  2. Traffic on the opposite side may cross, but the driver may not Correct answer.
  3. The driver may cross to overtake if the road is clear
  4. Neither direction may cross at any point

Explanation

On a double centre line the line nearest the driver controls that driver. A continuous line on the driver's side forbids crossing, while the broken line permits traffic on the other side to cross when safe. The rule therefore differs by direction of travel.

Question 34Road signs and markings

A driver sees a triangular warning sign showing a symbol of a tram. What should the driver expect?

  1. A compulsory turn for trams only
  2. A tramway crossing or tram tracks ahead Correct answer.
  3. A tram stop where passengers cross the road
  4. Trams are banned from this road

Explanation

A warning triangle with a tram symbol alerts the driver to tram tracks or a tram crossing ahead. Trams have priority and cannot steer around obstacles, so the driver should reduce speed and be ready to stop. The sign warns of a hazard rather than announcing a ban.

Question 35Road signs and markings

A driver sees a sign showing a red circle with a white arrow curving to the left and a red diagonal line across the arrow. What does this sign mean?

  1. Keep left of the traffic island
  2. Turn left is compulsory
  3. Turning left is prohibited Correct answer.
  4. Sharp bend to the left ahead

Explanation

A red diagonal line drawn across a direction arrow cancels that movement. The sign therefore forbids turning in the direction shown, in this case left. Without the diagonal line the same blue sign would make the turn compulsory.

Question 36Road signs and markings

A driver sees a yellow zigzag line painted along the edge of the carriageway near a pedestrian crossing. What does this marking mean?

  1. Loading is permitted for delivery vehicles
  2. Parking and stopping are prohibited in the marked area Correct answer.
  3. Parking is allowed for up to fifteen minutes
  4. Overtaking is permitted inside the zigzag

Explanation

Yellow zigzag markings guard the approach to pedestrian crossings. Stopping and parking there are prohibited because a stationary vehicle would block the view of pedestrians and approaching drivers. The restriction applies to all vehicles, including delivery vehicles.

Question 37Road signs and markings

A driver sees a sign showing a white symbol of an adult and child walking on a blue circular background. What does this sign indicate?

  1. A footpath shared with cyclists
  2. Pedestrians are prohibited
  3. Pedestrians must use this route Correct answer.
  4. A pedestrian crossing is ahead

Explanation

A blue circular sign gives a mandatory instruction. With pedestrian symbols it designates a route that pedestrians must use, for example a segregated footpath. It is not a warning of a crossing ahead.

Question 38Road signs and markings

A driver approaches a junction and sees a sign with a red border showing a black arrow bending sharply to the right. What does this sign warn of?

  1. A series of bends, the first to the right Correct answer.
  2. A compulsory right turn at the junction
  3. A side road joining from the right
  4. A right-hand lane reserved for turning

Explanation

A triangular sign with a red border and a bending arrow warns of a succession of bends ahead, starting in the direction shown. The driver should reduce speed before entering the first bend. A compulsory turn would be shown on a blue circular sign.

Question 39Road signs and markings

A driver sees a broken white line across the entry to a junction together with a give-way sign. How should the driver treat the broken line?

  1. It marks the limit of the priority road and where yielding begins Correct answer.
  2. It marks the edge of a pedestrian crossing area
  3. It marks a lane reserved for turning traffic
  4. It marks where the driver must stop completely before proceeding

Explanation

A broken white line across a junction entry marks the boundary at which the driver leaves the priority road and must yield. The driver should not cross it until the way is clear. Unlike a solid stop line, it does not require a complete stop when nothing is approaching.

Question 40Road signs and markings

A driver sees a sign with a red border showing a black lorry and a red diagonal line, placed at the entrance to a residential street. What is the effect of this sign?

  1. Lorries must use the left-hand lane
  2. Lorries are prohibited from entering the street Correct answer.
  3. Lorries may enter only to load or unload
  4. Lorries must reduce speed to 30 km/h

Explanation

A red circle with a diagonal line across a lorry symbol bans goods vehicles of the class shown from passing the sign. The prohibition is absolute unless a supplementary plate states an exception. The driver must find another route.

Question 41Traffic rules and right-of-way

You approach a road junction with no signs and no road markings. A tram is coming from the right on its rails. Who has priority?

  1. Whoever reaches the junction centre first
  2. You, because trams must always yield to cars
  3. The tram, because it approaches from your right Correct answer.
  4. You, because you are on the wider road

Explanation

At an unmarked junction the general rule is to yield to traffic approaching from the right, and this applies to trams as well. Trams run on fixed rails and cannot swerve or stop quickly, so the law also gives them priority in these situations. You must slow down and let the tram pass before continuing.

Question 42Traffic rules and right-of-way

What does a flashing red traffic light at a level crossing mean for you?

  1. Proceed with caution at normal speed
  2. Sound the horn and continue
  3. Stop and wait until the flashing stops Correct answer.
  4. Slow down and cross if no train is visible

Explanation

A flashing red signal is an absolute stop instruction, exactly like a steady red light. You must stop before the crossing and stay stopped while the signal flashes, even if you see or hear no train. Proceeding while the signal is active is a serious offence.

Question 43Traffic rules and right-of-way

A traffic controller stands at the junction with his arm raised vertically. What must you do?

  1. Stop, unless you are already too close to stop safely Correct answer.
  2. Continue, because the raised arm applies only to pedestrians
  3. Turn on your hazard lights and drive on
  4. Proceed only if you are turning right

Explanation

A raised arm by a traffic controller means stop for all traffic approaching the junction. The only exception is a driver who is so close that stopping abruptly would be dangerous. The controller's signals override traffic lights and road signs.

Question 44Traffic rules and right-of-way

You are driving on a road with a solid white centre line. A slow tractor ahead is blocking your lane. What is the correct action?

  1. Wait behind the tractor until the line becomes broken Correct answer.
  2. Overtake by driving partly on the shoulder
  3. Flash your headlights until the tractor pulls over
  4. Overtake by crossing the solid line if the road is clear

Explanation

A solid centre line may not be crossed for overtaking, because it marks a stretch where visibility or road layout makes the manoeuvre unsafe. You must stay behind the slow vehicle until the marking permits overtaking. Patience here prevents head-on collisions.

Question 45Traffic rules and right-of-way

At a pedestrian crossing marked with white stripes and no traffic lights, a pedestrian is waiting on the pavement but has not stepped onto the road. What must you do?

  1. Stop completely and switch off the engine
  2. Sound the horn to warn the pedestrian
  3. Slow down and be ready to stop, giving way if the pedestrian starts to cross Correct answer.
  4. Maintain speed because the pedestrian is still on the pavement

Explanation

At an unmarked-by-lights zebra crossing you must approach with care and be prepared to stop for pedestrians. Once a pedestrian shows an intention to cross, you must give way. You are not obliged to switch off the engine, but you must be able to stop safely.

Question 46Traffic rules and right-of-way

You are joining a motorway from an acceleration lane. Who has priority?

  1. The vehicle closest to the lane marking, regardless of direction
  2. Traffic already on the motorway Correct answer.
  3. You, because you are entering from a slip road
  4. You, if you signal before merging

Explanation

Vehicles already on the motorway have priority, and you must adjust your speed in the acceleration lane to merge safely into a gap. You must not force other drivers to brake or change lanes. Signalling shows your intention but does not give you priority.

Question 47Traffic rules and right-of-way

On a two-way road, when may you use your front fog lights?

  1. Only when visibility is seriously reduced by fog, snow or heavy rain Correct answer.
  2. Whenever you drive outside a built-up area
  3. At any time during the night
  4. Only when you are parked

Explanation

Front fog lights are meant for conditions of seriously reduced visibility such as fog, snowfall or heavy rain. Using them in clear conditions can dazzle other drivers and is not permitted. They are not a general night-driving light.

Question 48Traffic rules and right-of-way

What is the maximum permitted blood alcohol level for a driver in Bulgaria?

  1. 0.2 per mille
  2. 0.8 per mille
  3. 0.5 per mille Correct answer.
  4. Zero, with no tolerance at all

Explanation

Bulgarian law sets the general limit for drivers at 0.5 per mille blood alcohol, with stricter rules for novice and professional drivers. Even below this limit, you must not drive if your ability is impaired. Alcohol slows reactions and narrows attention.

Question 49Traffic rules and right-of-way

You are turning left at a junction with a green circular light. Oncoming traffic is approaching. What should you do?

  1. Sound the horn and complete the turn
  2. Wait in the junction and yield to oncoming traffic before completing the turn Correct answer.
  3. Reverse out and take another route
  4. Turn immediately, because green gives you absolute priority

Explanation

A green circular light allows you to proceed, but when turning left across oncoming traffic you must give way to vehicles coming straight towards you. You may move into the junction to wait for a safe gap. Green does not create priority over oncoming vehicles.

Question 50Traffic rules and right-of-way

You are driving on a road with priority (the priority road sign is displayed) and reach a junction where a side road joins from the right. A car is waiting there. Who has priority?

  1. The car, because it is stationary
  2. The waiting car, because it is on your right
  3. You, because you are on the priority road Correct answer.
  4. Whichever vehicle moves first

Explanation

When the priority road sign applies, vehicles on that road have right of way over traffic joining from side roads. The right-hand rule does not apply at such junctions. You should still approach with care in case another driver misjudges the situation.
