Question 1Czech Framework

In normal conditions, what is the general maximum speed for a Category B passenger car inside a built-up area in the Czech Republic?

  1. 30 km/h
  2. 50 km/h Correct answer.
  3. 70 km/h
  4. 90 km/h

Explanation

The general built-up-area limit for a passenger car is 50 km/h unless a sign sets a different limit. The limit is a maximum, so weather, visibility, traffic, and road condition may require a lower speed.

Question 2Czech Framework

Outside a built-up area, what is the general maximum speed for a Category B passenger car on an ordinary road unless signs say otherwise?

  1. 50 km/h
  2. 70 km/h
  3. 90 km/h Correct answer.
  4. 130 km/h

Explanation

For a Category B passenger car on an ordinary road outside a built-up area, the general maximum speed is 90 km/h. Higher limits apply only on roads designated for motor vehicles or motorways, and lower posted limits override the general rule.

Question 3Czech Framework

What is the general maximum speed for a Category B car on a road for motor vehicles outside a built-up area unless signs set a different limit?

  1. 80 km/h
  2. 90 km/h
  3. 110 km/h Correct answer.
  4. 130 km/h

Explanation

A road for motor vehicles is a higher-standard road but is not the same as a motorway. For a Category B car outside a built-up area, the general maximum is 110 km/h unless signs impose another limit.

Question 4Czech Framework

On a motorway passing through a built-up area, what general maximum speed applies to a Category B car unless traffic signs set another limit?

  1. 50 km/h
  2. 80 km/h Correct answer.
  3. 110 km/h
  4. 130 km/h

Explanation

Motorways and roads for motor vehicles inside a built-up area have a lower general limit than outside. For Category B driving, the general maximum is 80 km/h unless signs say otherwise.

Question 5Czech Framework

What is the role of the Ministry of Transport in the Czech theory test question set?

  1. It issues the official wording of test questions Correct answer.
  2. It lets each driving school invent official questions
  3. It requires questions to be chosen by vehicle dealers
  4. It has no role in the question set

Explanation

The Ministry of Transport states that it issues the wording of the official questions for the theory examination. Driving schools prepare candidates, but they do not create the official state question wording.

Question 6Czech Framework

Why is it risky to rely only on unofficial online question copies when studying for the Czech theory test?

  1. The Ministry issues official questions and eTesty is the official portal, so unofficial copies may be outdated or inaccurate Correct answer.
  2. Unofficial copies always give extra legal priority
  3. The official test contains no road rules
  4. The test is scored only on spelling

Explanation

The Ministry of Transport is the official source for test question wording, and eTesty is the official practice portal. Unofficial material can be useful only if it is accurate and current, but it should not replace official sources.

Question 7Priority Signs

At an uncontrolled intersection with no signs, signals, or police officer, which general priority rule applies?

  1. The larger vehicle always goes first
  2. The vehicle from the right has priority Correct answer.
  3. The fastest vehicle goes first
  4. The vehicle on the wider road always goes first

Explanation

When no higher control applies, Czech traffic rules use priority from the right. A driver must slow and be ready to yield to vehicles approaching from the right.

Question 8Priority Signs

Which control has the highest authority at an intersection?

  1. A police officer directing traffic Correct answer.
  2. A traffic light
  3. A priority sign
  4. The priority-from-the-right rule

Explanation

A police officer's traffic directions override lights, signs, road markings, and general priority rules. Drivers must follow the officer's signals even if another control would normally give a different instruction.

Question 9Priority Signs

What must a driver do at a STOP sign?

  1. Slow down and continue if the road looks clear
  2. Stop only if another vehicle is already in the intersection
  3. Come to a complete stop at the required place and then yield as required Correct answer.
  4. Flash headlights and proceed carefully

Explanation

A STOP sign requires a full stop at the stop line or, if there is no line, at a place with a sufficient view. After stopping, the driver must still yield according to the priority rule shown by the sign or situation.

Question 10Priority Signs

When a driver turns left at an intersection, what must the driver normally do about oncoming traffic?

  1. Yield to oncoming vehicles and trams that would be crossed Correct answer.
  2. Always turn before oncoming vehicles because turning left has priority
  3. Stop only if a horn is sounded
  4. Yield only to buses, not to cars

Explanation

A driver turning left normally crosses the path of oncoming traffic and must yield to it. This includes trams where the turning movement crosses the tram's path.

Question 11Priority Signs

What is the basic rule before changing lanes?

  1. Signal only after the lane change has started
  2. Change lanes if your vehicle is faster
  3. Give way to vehicles in the lane you want to enter and signal your intention Correct answer.
  4. Use the horn instead of the turn signal

Explanation

Before a lane change, the driver must check that the movement can be made safely, signal, and yield to vehicles already using the target lane. The signal warns others but does not give priority.

Question 12Priority Signs

What is prohibited for a driver while driving?

  1. Using a hands-free navigation instruction
  2. Holding a phone or similar device in the hand Correct answer.
  3. Listening to normal traffic radio
  4. Wearing prescription glasses

Explanation

A driver must not hold a phone or similar communication or recording device while driving. Hands-free use does not remove the duty to pay full attention to driving.

Question 13Priority Signs

What must a driver do when approaching a pedestrian crossing where a pedestrian is already crossing?

  1. Speed up to clear the crossing first
  2. Sound the horn and continue
  3. Allow the pedestrian to cross safely Correct answer.
  4. Drive around the pedestrian on the crossing

Explanation

Drivers must not endanger pedestrians on a crossing and must allow them to cross safely. Speed must be reduced early enough to stop if necessary.

Question 14Priority Signs

When must seat belts be used in a passenger car?

  1. Only on motorways
  2. Only by the driver
  3. By occupants where a seat belt is fitted and use is required Correct answer.
  4. Only outside built-up areas

Explanation

Seat belts are required for occupants in seats equipped with belts, subject to narrow legal exceptions. The rule is not limited to the driver, to motorways, or to rural roads.

Question 15Priority Signs

What should a driver do when an emergency vehicle approaches using blue warning lights and a siren?

  1. Ignore it unless it is directly behind
  2. Create a clear path and, if necessary, stop safely Correct answer.
  3. Follow it closely to pass traffic
  4. Stop immediately in any lane without checking mirrors

Explanation

Drivers must allow emergency vehicles using warning signals to pass. The correct response is controlled and predictable: make space, avoid blocking the route, and stop safely if needed.

Question 16Priority Signs

When traffic is forming a queue on a motorway with two or more lanes in one direction, how should drivers create the emergency corridor?

  1. All vehicles move to the left edge
  2. All vehicles move to the right edge
  3. Vehicles in the left lane move left and vehicles in the other lanes move right Correct answer.
  4. Only trucks move aside

Explanation

The rescue corridor is formed between the leftmost lane and the lane immediately to its right. Drivers in the left lane move left; drivers in all other lanes move right.

Question 17Priority Signs

When passing a cyclist on a road, what is the key legal and safety requirement?

  1. Pass as closely as possible to avoid crossing the centre line
  2. Keep a safe lateral distance, generally at least 1.5 metres Correct answer.
  3. Use the horn continuously while passing
  4. Pass only if the cyclist waves you through

Explanation

Czech law requires a safe side distance when passing a cyclist, with the commonly tested standard of at least 1.5 metres. The pass must also be safe for oncoming traffic and road conditions.

Question 18Priority Signs

When may a driver enter a railway crossing?

  1. Whenever the barriers are still raised
  2. Only when it is safe and the driver can clear the crossing completely Correct answer.
  3. When the vehicle ahead has just entered it
  4. If the red lights are flashing but no train is visible

Explanation

A driver must enter a railway crossing only when it is safe and there is enough space to leave it completely. Red lights, bells, moving barriers, or a blocked exit all mean the driver must not proceed.

Question 19Priority Signs

What does a solid white lane line generally mean?

  1. It may be crossed freely
  2. It separates lanes but crossing is generally prohibited except where allowed by law Correct answer.
  3. It marks only a parking place
  4. It cancels all traffic signs

Explanation

A solid lane line indicates a boundary that drivers generally must not cross. Exceptions are limited and must be safe and legally permitted, such as avoiding an obstacle in some circumstances.

Question 20Priority Signs

When must a driver use direction indicators?

  1. Only when another vehicle is visible
  2. Only during a driving test
  3. Before changing direction or lane when the signal can warn others Correct answer.
  4. Only at night

Explanation

Direction indicators are required before turning, changing lanes, moving off, leaving the road edge, or making similar movements where other road users need warning. The signal must be timely and must not mislead.

Question 21Priority Signs

A bus at a stop in a built-up area signals that it is leaving the stop. What must nearby drivers do?

  1. Always pass before the bus moves
  2. Allow the bus to leave if this can be done without sudden danger Correct answer.
  3. Stop for five minutes
  4. Sound the horn to tell the bus to wait

Explanation

Drivers must enable a bus leaving a stop in a built-up area to rejoin traffic when it signals. The bus driver must also act carefully; the rule is meant to keep public transport moving without creating sudden danger.

Question 22Priority Signs

What is the correct rule for daytime vehicle lighting in the Czech Republic?

  1. Lights are needed only at night
  2. A motor vehicle must use appropriate lights while driving, including daytime running lights or dipped beams where allowed Correct answer.
  3. Only front fog lights are required in daylight
  4. Lights are prohibited in daylight because they dazzle others

Explanation

Czech road rules require motor vehicles to be lit while driving; daytime running lamps or dipped headlights are commonly used depending on vehicle equipment and conditions. In reduced visibility, dipped headlights and other required lights must be used appropriately.

Question 23Priority Signs

What is prohibited on a motorway except in an emergency or where expressly allowed?

  1. Using direction indicators
  2. Stopping, reversing, or turning around Correct answer.
  3. Keeping a safe following distance
  4. Using dipped headlights

Explanation

Motorways are designed for continuous high-speed traffic, so stopping, reversing, and turning around are prohibited except in genuine emergencies or controlled situations. Drivers must continue to a suitable exit or safe stopping place.

Question 24Priority Signs

When overtaking, what must the driver be sure of before moving out?

  1. That the vehicle being overtaken is below the speed limit
  2. That no vehicle behind has started overtaking and the pass can be completed safely Correct answer.
  3. That the driver can exceed any speed limit if needed
  4. That oncoming drivers will brake if necessary

Explanation

Before overtaking, the driver must check mirrors and blind spots, make sure no one behind is already overtaking, and confirm that there is enough clear distance to complete the pass safely. Overtaking does not suspend speed limits or the duty to avoid danger.

Question 25Priority Signs

Which statement about pedestrian crossings is correct?

  1. You may overtake immediately before a crossing if your lane is clear
  2. You must approach so you can stop for pedestrians and must not endanger them Correct answer.
  3. Pedestrians on a crossing must always yield to cars
  4. A horn signal gives you priority over pedestrians

Explanation

Pedestrian crossings require special caution because pedestrians may already be crossing or about to cross. Drivers must reduce speed as needed and must not endanger pedestrians on or near the crossing.

Question 26Priority Signs

On a multi-lane road outside a built-up area, which lane should a driver normally use?

  1. The left lane, because it is safest
  2. Any lane at random
  3. The right lane, using other lanes mainly for overtaking, turning, or avoiding obstacles Correct answer.
  4. The lane with the smoothest pavement regardless of traffic

Explanation

Outside built-up areas, drivers should generally keep to the right lane and use other lanes for lawful purposes such as overtaking. This keeps faster and passing traffic predictable.

Question 27Priority Signs

What is the correct approach to a yellow traffic light shown after green?

  1. Always accelerate through it
  2. Stop if it can be done safely; continue only if stopping would be unsafe Correct answer.
  3. Ignore it because only red has meaning
  4. Reverse behind the stop line

Explanation

A yellow light warns that red is coming and generally requires stopping. If the vehicle is so close that safe stopping is not possible, the driver may continue through carefully.

Question 28Priority Signs

When entering a roundabout, what decides whether you must yield?

  1. Only the size of your vehicle
  2. The signs and markings at the entry, commonly Give Way signs Correct answer.
  3. The fact that every entering vehicle always has priority
  4. The colour of the vehicle already on the roundabout

Explanation

Roundabout priority is controlled by the signs and markings at the entry. In practice, Czech roundabouts commonly have Give Way signs for entering traffic, but the driver must read the actual controls.

Question 29Priority Signs

What is a driver's duty when approaching children near a road or school area?

  1. Assume children will always follow the rules
  2. Increase attention, reduce speed if needed, and be ready for sudden movement Correct answer.
  3. Drive closer to the centre line and maintain speed
  4. Use the horn continuously so children move away

Explanation

Children are vulnerable and may act unpredictably, so the driver must use extra caution. A safe speed and readiness to stop are more important than relying on children to judge traffic correctly.

Question 30Priority Signs

You are driving behind a vehicle that stops before a pedestrian crossing and blocks your view of the crossing. What is the safest and legally correct response?

  1. Overtake quickly before pedestrians step out
  2. Slow or stop and do not pass unless you are sure it is permitted and safe Correct answer.
  3. Sound the horn and drive around
  4. Move into the opposite lane because the stopped vehicle has given up priority

Explanation

A stopped vehicle before a crossing may be yielding to a pedestrian hidden from your view. Overtaking near a crossing is a serious hazard, so you must approach cautiously and be prepared to stop.

Question 31Priority Signs

A tram is approaching from behind in a tram lane while you intend to turn across that lane. What should you do?

  1. Turn first because cars always have priority over trams
  2. Yield if your turn would cross or obstruct the tram's path Correct answer.
  3. Stop on the tram track and wait for a gap
  4. Signal left and force the tram to slow

Explanation

When a driver's manoeuvre crosses a tram's path, the driver must account for the tram's priority and stopping distance. You must not obstruct the tram lane or force the tram into emergency braking.

Question 32Priority Signs

In dense slow traffic, what is the zipper merging principle used for where a lane is ending?

  1. All vehicles in the continuing lane must stop completely
  2. Drivers use both lanes up to the merge point and then alternate one by one Correct answer.
  3. Vehicles in the ending lane must reverse to the back of the queue
  4. The largest vehicles always merge first

Explanation

The zipper principle keeps capacity available and reduces disorder at lane closures. Drivers in both lanes should proceed to the merge area and then alternate with mutual cooperation.

Question 33Priority Signs

You are on a priority road, but a police officer signals you to stop and lets side-road traffic proceed. What must you do?

  1. Continue because the priority-road sign controls the situation
  2. Stop and obey the police officer's signal Correct answer.
  3. Flash headlights and proceed slowly
  4. Follow the vehicle ahead even if the officer signals stop

Explanation

Police traffic directions override priority signs and traffic lights. Even on a priority road, the driver must obey the officer's signal.

Question 34Priority Signs

A driver wants to pass a slow vehicle just before the crest of a hill on a two-way road. Why is this usually unsafe and prohibited?

  1. The engine may use more fuel uphill
  2. The driver cannot see enough clear road to complete the overtake safely Correct answer.
  3. The slow vehicle always has priority forever
  4. Overtaking is allowed only downhill

Explanation

Before overtaking, the driver must be able to see that the opposing lane is clear for the whole manoeuvre. A crest can hide oncoming traffic, making the overtake dangerous even if no vehicle is currently visible.

Question 35Priority Signs

You have a green light but the intersection is blocked by traffic ahead. What should you do?

  1. Enter anyway because green gives absolute priority
  2. Wait before the intersection until there is space to clear it Correct answer.
  3. Stop in the middle and use hazard lights
  4. Drive onto the pedestrian crossing to wait

Explanation

A green signal permits movement only if the driver can proceed safely and lawfully. Entering a blocked intersection can obstruct cross traffic and pedestrians when the signals change.

Question 36Priority Signs

When is it especially important to reduce speed below the posted limit?

  1. Only when a police car is visible
  2. When road, traffic, weather, visibility, vehicle, or driver conditions make the posted speed unsafe Correct answer.
  3. Only after a collision has already happened
  4. Only on roads without centre lines

Explanation

The posted limit is a maximum, not a target. Czech safe-speed rules require the driver to adapt speed so the vehicle remains controllable and can be stopped within the visible, safe distance.

Question 37Priority Signs

A driver is approaching a level crossing and traffic beyond the crossing is backed up. What is the correct action?

  1. Enter the crossing because the barriers are open
  2. Wait before the crossing until there is enough space beyond it Correct answer.
  3. Stop on the tracks and leave the engine running
  4. Follow the vehicle ahead closely to avoid a gap

Explanation

A driver must not enter a railway crossing unless able to clear it completely. Open barriers do not make it safe to stop on the tracks because a train warning can begin while the vehicle is trapped.

Question 38Priority Signs

What is the safest general following-distance habit in normal traffic?

  1. Keep enough distance to stop safely if the vehicle ahead brakes suddenly Correct answer.
  2. Drive as close as possible so no one merges in
  3. Watch only the brake lights of the vehicle ahead
  4. Use a fixed one-metre gap at all speeds

Explanation

A safe following distance changes with speed, road surface, visibility, reaction time, and vehicle condition. The gap must be large enough to allow controlled stopping if traffic ahead brakes unexpectedly.

Question 39Priority Signs

Why should you look far ahead as well as at the vehicle directly in front?

  1. It lets you ignore speed limits
  2. It helps you detect developing hazards early and drive smoothly Correct answer.
  3. It replaces mirror checks
  4. It is needed only on motorways

Explanation

Looking well ahead gives more time to notice brake lights, pedestrians, merging vehicles, traffic lights, and road changes. Early detection supports smoother braking and fewer emergency manoeuvres.

Question 40Priority Signs

Why should you slow before entering a tunnel?

  1. Tunnel lighting and traffic conditions can change suddenly, and escape space is limited Correct answer.
  2. The law requires stopping before every tunnel
  3. Engines always lose power in tunnels
  4. Headlights are prohibited in tunnels

Explanation

Tunnels can contain queues, incidents, changed lighting, and limited shoulders. Slowing and increasing distance before entry gives more time to react inside the confined space.

Question 41Priority Signs

Why should a driver leave extra space when following a motorcycle?

  1. Motorcycles never brake
  2. A motorcycle can brake or change position quickly and is more vulnerable in a collision Correct answer.
  3. Motorcycles are legally invisible
  4. Cars are required to follow motorcycles at walking speed

Explanation

Motorcycles are narrow, can be hidden in blind spots, and their riders are exposed. Extra space gives time to react if the motorcycle brakes, swerves, or avoids a surface hazard.

Question 42Priority Signs

What is the safest response if a ball rolls into the road ahead?

  1. Assume no one will follow it
  2. Be prepared for a child or other pedestrian to run after it and slow immediately Correct answer.
  3. Drive over it at normal speed
  4. Sound the horn but keep speed

Explanation

A ball in the road is a classic warning that a child may enter the road without looking. The safest response is to slow early, cover the brake, and be ready to stop.

Question 43Priority Signs

What does a red-bordered triangular sign generally indicate?

  1. A warning about a hazard ahead Correct answer.
  2. A motorway service area
  3. A parking permit zone
  4. An end of all restrictions

Explanation

A red-bordered triangle is a warning sign shape in Czech and European road signing. It alerts drivers to hazards such as curves, intersections, crossings, animals, or roadworks-related dangers.

Question 44Priority Signs

What does a circular sign with a red border usually mean?

  1. A prohibition or restriction Correct answer.
  2. A tourist attraction
  3. A recommended route only
  4. A railway station

Explanation

Circular signs with red borders usually impose prohibitions or restrictions, such as no entry for certain vehicles, speed limits, or no overtaking. Drivers must obey the specific symbol or number shown.

Question 45Priority Signs

What does the inverted red-and-white triangle mean?

  1. Stop and wait for a police officer
  2. Give way Correct answer.
  3. Priority road
  4. No parking

Explanation

The inverted triangle is the Give Way sign. It requires the driver to yield to traffic on the road that has priority and to stop if necessary.

Question 46Priority Signs

What does a yellow diamond priority sign mean?

  1. The road is a priority road Correct answer.
  2. All vehicles must stop
  3. The road is closed to cars
  4. Parking is free

Explanation

A yellow diamond indicates a priority road. Traffic on that road has priority over traffic from side roads until the priority road ends or another control changes the situation.

Question 47Priority Signs

What does a blue circular sign with a white arrow usually indicate?

  1. A mandatory direction or movement Correct answer.
  2. A warning only
  3. A cancellation of speed limits
  4. A private road marker

Explanation

Blue circular signs usually give mandatory instructions, such as the required direction of travel or a required side to pass. The driver must follow the displayed instruction unless another higher control directs otherwise.

Question 48Priority Signs

What is the meaning of a red circular sign with a horizontal white bar?

  1. No entry for vehicles from this direction Correct answer.
  2. Priority over oncoming traffic
  3. End of a one-way street
  4. Emergency parking only

Explanation

The red sign with a horizontal white bar is the no-entry sign. It prohibits entering from that direction, even if the road may be used by traffic travelling the other way.

Question 49Priority Signs

What should a driver do at a flashing amber traffic signal?

  1. Treat it as permission to drive without caution
  2. Proceed with increased caution and follow signs and priority rules Correct answer.
  3. Stop for 30 seconds at every approach
  4. Assume all other traffic must yield

Explanation

A flashing amber light warns the driver to proceed cautiously. It does not itself assign priority, so signs, markings, and general priority rules must be applied.

Question 50Priority Signs

What does a solid line next to a broken line between opposing lanes mean for the driver beside the solid line?

  1. The driver may cross because the other side has a broken line
  2. The driver must generally not cross the line from the solid side Correct answer.
  3. The marking applies only to motorcycles
  4. The marking means no speed limits apply

Explanation

When a combined solid and broken centre marking is used, each driver follows the line nearest their vehicle. From the solid side, crossing is generally not allowed.
