Step 1. The big picture

In one sentence…
The LVA licence requires mastering general rules and signs applied to self-propelled special agricultural vehicles and their combinations within the permitted limits. The exam tests your ability to apply the hierarchy of signs to a wide, slow vehicle with wide manoeuvres.
Step 2. The syllabus
2.1Hierarchy of signing
Priority between signs is not arbitrary: you first obey the orders of officers, then temporary signing, then traffic lights, vertical signs and finally road markings.
- If two signs seem to contradict each other, the higher-ranking one prevails. In the exam, many questions are solved by remembering this hierarchy before looking at shape or colour.
- Signs apply from the point where they are placed, unless they state a distance, a section length or an end of prohibition.
- Memorise the full order because it is the basis for deciding when several indications coincide at the same point on the road.
2.2Families of signs
Danger warning signs warn of a risk; regulatory signs impose prohibitions or obligations; information signs guide, confirm or inform about the use of the road.
- Identifying the family by shape and colour tells you straight away whether a sign warns, prohibits, requires or simply informs.
- Regulatory signs directly condition your conduct, so they are the ones you must know best.
- Studying by families avoids learning loose pictures and helps you deduce the meaning of an unfamiliar sign.
2.3Traffic lights and road markings
Traffic lights regulate right of way with priority over an incompatible vertical sign; their lights can be aimed at all users or at a specific lane or manoeuvre.
- Road markings define lanes, excluded zones, pedestrian crossings, continuous or broken lines, and rules on stopping, parking and priority.
- A continuous line must not be crossed; a broken line allows certain manoeuvres only when it is safe to do so.
- Reading the markings well helps you position a wide combination without entering opposite lanes or reserved zones.
2.4Practical reading in the exam and on the road
Do not study signs as loose pictures: link each one to the required conduct, the vehicle's position and the anticipation needed.
- At a junction, a priority sign outweighs the general rule of giving way to the right; at roadworks, temporary signing can override the permanent one.
- When a question mentions a reversible lane, an additional lane or a temporary diversion, pay attention to road delineation devices, arrows and variable message panels.
- For every sign, ask yourself what conduct it requires and how far in advance you must start applying it with a slow vehicle.
2.5Official catalogue and the 2025 update
The official catalogue of signs was updated in 2025; the reform introduces new representations and adapts pictograms and panels to today's mobility.
- To study rigorously, use up-to-date material and be wary of old diagrams that keep withdrawn signs or incomplete meanings.
- If a question sets a new sign against a classic one, the key remains identifying danger, prohibition, obligation or information and applying the correct conduct.
- Whenever in doubt between an old version and a recent one, the official catalogue in force must always prevail.
2.6Signs relevant in LVA
In LVA you must watch especially for access signs, restrictions on dimensions, speed and priority, and the use of the hard shoulder or carriageway according to the type of special vehicle.
- Pay attention to signs restricting passage by width, height or weight, because an agricultural combination can be affected.
- Interpret each sign thinking about a wide, slow vehicle with wide turns, not only its general meaning.
- Reading the signing well in advance gives you margin to plan crossings and turns without surprising the rest of the traffic.
2.7Method for studying signs
Group signs by family and by expected conduct, and revise the ones that are most often confused with each other until you can tell them apart without hesitation.
- Practise with questions that place the sign in a real context of a junction, joining from a track, or a restriction by dimensions.
- When you get a question wrong, note why you confused the meaning and review that family before the next revision.
- Reviewing little and often fixes the catalogue in your memory better than a single long revision the night before the exam.
Step 3. Key points
If you only have a minute before the exam, revise this.
- 1.Recognise the full hierarchy of signing.
- 2.Distinguish danger, regulatory and information signs, markings and road delineation devices.
- 3.Understand the priority of a traffic light over an incompatible vertical sign.
- 4.Link each sign to the required conduct and the section affected.
- 5.Watch for restrictions by dimensions, speed and access.
- 6.Study the updated catalogue and not just old images.
- 7.Practise with questions that place the sign in a real context.
Step 4. Exam traps
Mistakes the DGT uses again and again on this topic.
- Confusing the general priority rule with a vertical sign or a working traffic light.
- Forgetting that temporary roadworks signing can change the usual regime.
- Reading an isolated road marking without linking it to the rest of the signing on the lane or junction.
- Studying with old diagrams instead of the official catalogue in force.
- Interpreting signs without taking into account the width and slowness of the combination.
Step 5. Quick check
Four real exam questions on what you have just read.
On the date of the first practical-test attempt for the LVA licence, the applicant must:
Step 6. Frequently asked questions about traffic rules and signs
- Under the wording of Annex VI.A.2 of the General Driver Regulations, what minimum interval is specified between successive attempts after the third, except for a justified exceptional reduction?
- 15 days. Annex VI. A.2 specifies a minimum of fifteen days between successive attempts after the third. After two unsuccessful attempts, it specifies ten days between the second and third. The intervals run from the date of the unsuccessful test and may exceptionally be reduced for justified urgency. This question concerns the interval expressed in the regulation; the traffic authority determines the actual test date.See full question
- If a traffic officer is directing traffic while you drive an agricultural vehicle requiring an LVA licence, you must:
- Follow the officer's instructions. When traffic officers direct traffic, their instructions take precedence over fixed signs.See full question
- Under the provision in Annex VI.B.1 of the General Driver Regulations, how many correct answers may a knowledge-test question have?
- From one to four correct answers. The annex provides for one to four correct answers. This question concerns the regulatory text and does not assert that all current exams contain multiple-correct-answer questions: transitional provision eleven makes application of those characteristics depend on the date set by ministerial order. Follow each exam’s instructions; this practice bank asks for one correct option.See full question
- If an exam center outside the provincial capital stops meeting the required conditions for the LVA licence:
- The tests move to the capital or another suitable center in the same province. Until the deficiencies are corrected, the tests will be held in the provincial capital or at another suitable center in the same province.See full question
- During the practical tests for the LVA licence, the use of phones or other data-transmission systems:
- Is not allowed, except for the regulatory exceptions. During the practical tests of skills and behavior, the use of phones and systems for capturing, recording, receiving, or transmitting data or information is not allowed, except for the regulatory exceptions.See full question
