Step 1. The big picture
In one sentence…
The LCM licence relies on general rules and signs applied to vehicles for people with reduced mobility: priority, position on the road and correct reading of signs. The exam tests your ability to apply that order of priority to a slow and especially vulnerable vehicle.
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 yourself prudently without entering zones reserved for pedestrians or other road users.
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.
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.
2.6Signing and circulation in LCM
In the LCM licence you must link signs to low-speed circulation and to prudent use of roads where your vehicle can be especially vulnerable.
- Pay attention to signs that regulate coexistence with pedestrians and to those that limit access to, or use of, certain roads.
- Interpret each sign thinking about how it affects a slow, exposed vehicle, not only its general meaning.
- Reading the signing well in advance gives you margin to correct smoothly, which is key when your speed and protection are lower.
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, lane or coexistence with pedestrians, not just the isolated image.
- 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.Read the signing thinking about a slow, vulnerable vehicle.
- 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 how vulnerable the vehicle is.
Step 5. Quick check
Four real exam questions on what you have just read.
Under Annex VI of Spain’s Driver Regulations, after failing an LCM licence test twice, what general minimum interval is specified between the second and third attempts?
Step 6. Frequently asked questions about rules and road signs
- To take a practical test for the LCM licence, which documents may an applicant be required to present for identification, as applicable?
- ID card, passport, residence card, or driving licence, as applicable. Annex VI of the General Driver Regulations allows applicants to be required to present a national identity card, passport, residence card or driving licence, as applicable, for practical tests. A photocopy of a family record book or a payment receipt does not replace the required identification document.See full question
- Speed limits when driving a vehicle for persons with reduced mobility:
- Must be respected and also adapted to traffic conditions. Speed limits must be respected and, in addition, speed must be adapted to the specific road and traffic conditions.See full question
- If the vehicle or required systems for the the LCM licence test do not function properly:
- The test does not start or is interrupted without losing the attempt. If they do not function properly or do not meet the required conditions, the test does not start or is interrupted without loss of the attempt.See full question
- If you are driving a vehicle for people with reduced mobility and you approach a yield sign, you must:
- Yield to whoever has priority. Give way to vehicles with priority, slowing down and stopping if necessary. A give-way sign does not require a stop in every case, unlike STOP. Driving a vehicle for people with reduced mobility does not remove this obligation.See full question
- If you are driving a vehicle for people with reduced mobility and a traffic officer is directing traffic, you must:
- Obey the officer's instructions. When traffic officers are directing traffic, their instructions take precedence over fixed signs.See full question

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.
- LCMDriver safety
In LCM, driver safety depends on visibility, stability, adapted speed and prudent reading of the surroundings, because it is an especially exposed vehicle. The exam insists that low speed does not remove the risk and that being seen is an active responsibility.
- LCMVulnerable road users
In LCM two realities coincide: the driver themselves is very vulnerable, and they also share the road with pedestrians and other vulnerable users who require extra care. The exam wants you to understand that formal priority does not remove the risk and that visibility is everyone's responsibility.
- LCMVehicle and manoeuvres
The vehicle and manoeuvres topic in LCM requires knowing the basic controls, stability control, correctly occupying space and manoeuvring at low speed with full safety. The exam tests your ability to check beforehand, observe fully and use the available space prudently.
