1At an intersection without traffic lights, priority signs, or police officers, which vehicle has the right-of-way under the Luxembourg Code de la Route?

A.The vehicle traveling on the wider road

B.The vehicle traveling at higher speed

C.The vehicle that arrived at the intersection first

D.The vehicle approaching from the right

Explanation: Under the Luxembourg Code de la Route, the fundamental default priority rule at unsignalized and unsigned intersections is priority to the right (priorité à droite). Every driver must yield the right-of-way to vehicles approaching from their right side.

2Under what circumstance does a vehicle approaching from the right NOT have priority under Luxembourg traffic regulations?

A.When the vehicle on the right is a small passenger car

B.When the vehicle on the right is emerging from a dirt track, private driveway, or car park

C.When the vehicle on the right is turning right instead of going straight

D.When the vehicle on the right is driving below the posted speed limit

Explanation: Priority to the right does not apply to vehicles entering a public road from a non-public property, private path, dirt road (chemin de terre), or car park. Drivers exiting such locations must yield to all traffic already circulating on the public roadway.

3What is the legal obligation when approaching traffic sign B,1 (an inverted white triangle with a red border)?

A.You must come to a complete standstill in all circumstances before entering the intersection

B.You have priority over oncoming traffic but must yield to vehicles on the right

C.You must give way to traffic on the intersecting road, stopping only if necessary

D.You must accelerate to merge ahead of crossing traffic

Explanation: Sign B,1 ('Cédez le passage' / Give Way) requires drivers to yield the right-of-way to vehicles traveling on the crossing or intersecting roadway. A complete stop is only required if traffic on the priority road prevents you from proceeding safely.

4What must a driver do when facing sign B,2a (octagonal red sign with white 'STOP' lettering)?

A.Slow down to walking pace and proceed if the intersection is clear

B.Give way only to vehicles approaching from the right side

C.Stop only if another vehicle is approaching within 50 meters

D.Bring the vehicle to a complete stop at the stop line, or at the edge of the roadway if there is no line, and yield to all crossing traffic

Explanation: Sign B,2a (STOP) imposes a mandatory obligation to bring the vehicle to a full and complete standstill at the stop line (or at the intersection boundary if no line is marked) and yield the right-of-way to all traffic on the intersecting road.

5What is the meaning of road sign B,3 (a yellow square inside a white diamond)?

A.Priority road: you have right-of-way at subsequent intersections until an end-of-priority sign appears

B.Priority to the right resumes at the next intersection

C.Caution: dangerous intersection with traffic coming from the left

D.Single-lane road ahead: priority over oncoming traffic

Explanation: Sign B,3 ('Route à priorité') designates a priority road. Drivers on this road maintain right-of-way at successive intersections until sign B,4 (end of the priority road) or a contradictory sign is encountered.

6When driving past sign B,4 (a yellow square in a white diamond crossed by diagonal black stripes), what rule governs subsequent intersections?

A.You automatically have priority at the next three intersections

B.The priority road ends, and default priority to the right applies at subsequent intersections unless signed otherwise

C.All cross-traffic must yield to you until you enter a built-up area

D.You must stop before entering any following intersection

Explanation: Sign B,4 indicates the end of the priority road status. From this point onwards, standard intersection rules resume, meaning general priority to the right applies unless other priority signs are posted.

7When entering a roundabout (intersection à sens giratoire) indicated by sign D,3 and sign B,1, who has priority?

A.Vehicles entering the roundabout have priority over circulating vehicles

B.The vehicle traveling at higher speed has priority

C.Vehicles already circulating inside the roundabout have priority over entering vehicles

D.Entering traffic always has priority to the right

Explanation: Sign D,3 ('Intersection à sens giratoire obligatoire') marks a roundabout. When the entry also carries sign B,1 (Give Way), drivers entering must yield to traffic already circulating in the ring. Without a B,1 at the entry, the general priority-to-the-right rule of Article 136 would apply instead.

8What is the correct use of direction indicators when navigating a standard single-lane roundabout in Luxembourg?

A.Signal left before entering, keep signaling left in the roundabout, and never signal when exiting

B.Signal right before entering the roundabout even if taking the third exit

C.Keep the hazard warning lights flashing continuously while circulating

D.Do not signal when entering, and activate the right indicator immediately after passing the exit prior to the one you intend to take

Explanation: When you are not leaving at the first exit, you do not signal on entry; in Luxembourg your lane position, not a left indicator, shows that you are continuing around. You must switch on the right indicator after passing the exit before the one you intend to take, so waiting drivers know you are leaving.

9What does the zipper merge principle (principe de la tirette) require when a traffic lane is ending due to roadworks or an obstruction in slow-moving traffic?

A.Drivers in the ending lane must immediately stop and wait until the continuing lane is completely empty

B.Drivers in the ending lane must proceed to the very point of lane reduction, and drivers in the continuing lane must alternately allow one vehicle to merge

C.Drivers in the continuing lane have absolute right-of-way and are forbidden from letting merging vehicles in

D.Drivers must race to overtake as many cars as possible before changing lanes

Explanation: Under the Luxembourg Code de la Route, the zipper merge (principe de la tirette) is mandatory during heavy traffic. Drivers in the ending lane must use the lane up to the point of constriction, where drivers in the open lane must yield alternately (1:1 ratio) to let them merge smoothly.

10What sanction applies in Luxembourg if a driver fails to respect the mandatory zipper merge principle (principe de la tirette)?

A.A verbal warning without financial penalty

B.Deduction of 6 points from the driving licence

C.An immediate suspension of the driving licence for 6 months

D.A taxed warning (avertissement taxé) of €74

Explanation: Failing to apply the mandatory zipper merge principle when required by the Luxembourg Highway Code constitutes a traffic infraction subject to a €74 taxed warning (avertissement taxé).

About the Luxembourg Driving Theory Test Exam

The SNCA theory test (examen théorique) is the computer-based multiple-choice test that every Luxembourg driving-licence candidate must pass after the mandatory theory lessons. It covers the Luxembourg Code de la Route: priority rules, road signs and markings, speed limits, motorway and tunnel rules, safety equipment, alcohol limits and the 12-point licence. This 100-question bank is independent practice by OpenExamPrep, not the official SNCA question set. It is written in English; the real test can also be taken in Luxembourgish, French, German or Portuguese.

Exam sponsor: Société Nationale de Circulation Automobile (SNCA), Driving Licence Office (Service des permis de conduire), Sandweiler. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Luxembourg Driving Theory Test: Suggested Study Strategy

1Study the Code de la Route populaire, the simplified Highway Code handbook sold by La Sécurité Routière in French, German and English; the SNCA calls knowledge of it the best preparation for the theory and practical tests.

2Use the SNCA's free online demo (20 random questions) to get used to the test screen, but remember the real category B test has 54 questions in 30 minutes.

3Learn the Luxembourg sign codes: B,1 give way, B,2a STOP, B,3/B,4 priority road, D,3 roundabout, C,18/C,19 no parking/no stopping, and E,15/E,16 start/end of motorway.

4Memorise the speed limits, including 110 km/h on motorways in rain and 90 km/h in signed tunnels, and the 20 km/h and 30 km/h zones.

5Master Luxembourg-specific rules: 1.5 m clearance when overtaking cyclists, the zipper merge, the rescue corridor and the 12-metre no-stopping zone around bus stops.

6Know the sanctions that change behaviour: €250 and 4 points for a phone at the wheel, 0.2 g/l for novice drivers, and €30 re-admission if you need to resit the theory test.

Frequently Asked Questions

How many questions are on the Luxembourg driving theory test, and what is the pass mark?

The SNCA states that the category B theory test has 54 multiple-choice questions, with 30 minutes for a first licence (20 minutes if you already hold another licence). The SNCA does not publish the pass rule on its website. Approved driving schools report that you may make no more than 11 faults in total, with limits per section: 3 code, 3 signs and 2 priority in the common core, and 6 each in the category-specific code and signs.

In which languages can I take the SNCA theory test?

Guichet.lu states that the computer test can be taken, at the candidate's choice, in Luxembourgish, French, German, Portuguese or English. At the driving school's request, the SNCA can also hold an oral test by appointment, with a sworn interpreter if needed, on Mondays and Fridays in Sandweiler. This practice bank is in English and is independent of the SNCA.

What are the general speed limits in Luxembourg?

Unless signs show otherwise: 20 km/h in pedestrian zones, residential zones and meeting zones; 30 km/h in Zone 30 areas and cycle streets; 50 km/h in built-up areas; 90 km/h outside built-up areas; and 130 km/h on motorways. The motorway limit falls to 110 km/h in rain or other precipitation, and it is 90 km/h in signed tunnels.

What is the legal alcohol limit for drivers in Luxembourg?

The general limit is 0.5 g/l of blood (0.25 mg/l of exhaled air). A reduced limit of 0.2 g/l (0.1 mg/l of exhaled air) applies to licence candidates, drivers in their probationary period, accompanying persons, drivers under 18, and professional drivers such as taxi, bus and lorry drivers. From 0.5 g/l the sanction is €145 and 2 points; from 1.2 g/l it is a criminal offence.

What is the zipper merge (système tirette) in Luxembourg?

When one lane of a multi-lane road is closed and traffic slows, drivers in the ending lane move over only at the point of the closure. Drivers in the open lane must let them in alternately, one vehicle each. The rule is part of the Code de la Route, and failing to respect it costs a €74 taxed warning.

What are the winter tyre rules in Luxembourg?

Whenever wintry conditions occur (black ice, packed snow, slush, or patches of ice or frost), cars must be fitted with winter or all-season tyres marked M.S, M+S or M&S or bearing the alpine (mountain-and-snowflake) symbol, with four tyres of the same type. The rule has no fixed calendar dates, and breaking it costs €74.

How does the Luxembourg points-based licence (permis à points) work?

Every driver starts with 12 points, and offences cost 2, 4 or 6 points depending on their seriousness. Losing all 12 points suspends the right to drive for 12 months (24 months for a second time within 3 years). Drivers can recover 3 points once every 3 years through a one-day awareness course in Colmar-Berg, and all 12 points are restored after 3 years without a point-losing offence.

What training is mandatory during the probationary period?

After passing the practical test, new drivers hold a licence covering a 24-month training (probationary) period. During that period they must attend a one-day course at the Driver Safety Training Centre (CFC) in Colmar-Berg, which can be taken from the third month after the licence is issued. The certificate of participation leads to the final licence, which is valid for 10 years.
