Spanish Road Signs Explained in English (2026 Guide)

Spanish road signs are grouped into families by their function. The official catalogue, annexed to Royal Decree 465/2025, sets the shape, colour, design and meaning of each sign. Its vertical sign section groups the signs into families such as danger, priority, prohibition, obligation, end of restriction, lanes, services and direction.

The families you will meet most often are these:

• Danger warnings (señales de peligro): warn you of a hazard ahead. They are generally triangular with a red border.
• Priority (señales de prioridad): tell you who has right of way at a junction, for example the give-way and stop signs.
• Prohibition (señales de prohibición): forbid a manoeuvre or a type of traffic. They are generally round with a red border.
• Obligation (señales de obligación): tell you what you must do, such as a minimum speed or a compulsory direction. They are generally round and blue.
• Information (señales de indicación): give directions, place names and services. They are generally rectangular or square and blue or green.

The shape and colour tell you the family before you read the pictogram, so learning the families first makes every new sign easier to decode.

When you meet a sign for the first time, ask three questions. What is its shape? What colour is the border or background? Does the pictogram show an action you must take, an action you must avoid, or a place ahead? Answering those three questions identifies the family for most signs and gives you a solid starting point for working out the meaning. The exact wording and pictogram are then confirmed in the catalogue, which is the reference for any dispute.

In Spain, the shape and colour of a sign are fixed by the national catalogue rather than chosen locally. Article 134 of the RGC, as amended in 2025, requires the catalogue to specify the shape, colour, design and meaning of each sign. This is why a sign in Madrid looks the same as one in Galicia.

Colour can also change for a reason. According to the 2025 amendment, danger and regulatory signs placed for roadworks or maintenance use a yellow background, and circumstantial signs for other causes use orange. Lane signs for works switch to yellow with black symbols.

As a general rule, a red border usually means danger or prohibition, and a blue circle usually means an obligation. When you are unsure of a sign's exact design, check the catalogue annexed to the BOE text rather than relying on memory.

Under Article 133 of the RGC, the Spanish order of precedence for traffic signals runs from highest to lowest in the following way. Signals and orders from traffic agents rank first. Temporary signs and barriers come second. Traffic lights come third, vertical signs fourth, and road markings last. If two signals conflict, the higher-ranked one prevails. If they are the same type, the more restrictive one applies.

The ranking is in this order:

1. Orders and signals from traffic agents (agentes de la autoridad encargados de la vigilancia del tráfico).
2. Temporary signs, barriers and beacons that change the normal use of a road.
3. Traffic lights (semáforos).
4. Vertical traffic signs (señales verticales de circulación).
5. Road markings (marcas viales).

In practice, a police officer directing traffic overrides a green light, and a traffic light overrides a permanent sign that seems to say something different. Article 132 also requires users to obey signals that impose an obligation or prohibition.

Consider a worked example. Roadworks put up a temporary sign that asks you to slow down, while a permanent sign further back shows a higher limit. The temporary sign ranks higher in the order of precedence, so the lower restriction it sets is the one that applies. The rule of thumb is simple: the closer a signal sits to the actual situation, and the more it describes what is happening now, the more weight it carries.

Traffic lights (semáforos) rank above vertical signs in Spain, so a light that conflicts with a permanent sign is the signal you must follow. Road markings (marcas viales) are painted on the road surface and rank last, which means a sign or a light always overrides a painted line that appears to say otherwise.

Road markings still matter. Continuous lines generally restrict overtaking or crossing into another lane, while broken lines are usually more permissive. Because the rules for each marking are set in the catalogue, check its exact meaning in the official text if you are unsure.

A practical point: when a marking and a vertical sign seem to disagree, follow the sign, because the sign ranks higher under the RGC.

Markings also appear in several forms: lines along the lane, arrows on the surface, symbols and words painted at junctions, and markings on kerbs. Each type has its own meaning in the catalogue, so a single painted shape should never be read in isolation. Look at the markings together with the signs and lights around them, and remember that the signals above always have the final say.

Temporary signs (señales circunstanciales) are used for roadworks, accidents, events and other situations that change how a road is normally used. Under Article 133 they rank second, above traffic lights and permanent vertical signs, because they describe conditions that are happening now.

Orders from traffic agents rank first of all. A traffic agent may use gestures, a whistle or a torch, and these override every other signal on the road.

Article 131 of the RGC defines signage as the set of signals, agent orders and markings that warn, inform or regulate road users. Together with Article 133, this means temporary and agent signals are the ones to watch first on any road where conditions have changed.

Royal Decree 465/2025, dated 10 June 2025 and published in the BOE on 17 June 2025, amended the RGC on traffic signalling. It put the official catalogue of vertical signs and road markings into a single document annexed to the regulation, and it rewrote the signalling title of the RGC. It entered into force on 1 July 2025.

The decree sets out a few practical rules that drivers should know:

• Existing signs may stay in place until they are renewed.
• Suppressed signs had to be removed within one year, so by 1 July 2026.
• The catalogue, not local practice, sets the shape, colour, design and meaning of each sign.
• Secondary commentary reports new signs, including signs for personal mobility vehicles. Check the BOE annex for the full list.

If you learned your signs before 2025, it is worth checking the current catalogue, because some signs look or are described differently now.

For drivers, the practical effect is that a sign you see on the road may be an older design still awaiting renewal, or a newer one that has replaced it. Both are valid for the period set by the decree, but only the catalogue defines the official meaning. If a study guide and the catalogue disagree, the catalogue wins.

The P-21b is a danger warning sign that the official catalogue names «Personas con dificultades motrices», meaning people with mobility difficulties. It warns that you are approaching a place frequently used by people with mobility or sensory difficulties, so you should be prepared to slow down and watch for pedestrians.

The P-21b is often confused with a sign about older people. The catalogue name refers to mobility or sensory difficulties, not age, so use the catalogue wording when you describe the sign.

Like every danger warning, it does not itself impose a speed limit. It tells you to take extra care until you have passed the hazard.

The key lesson from the P-21b is about reading the catalogue wording rather than the picture alone. Two signs can look similar at a glance, and a wrong description can lead you to misremember what the sign is for. When you revise, note the official name and the family, and the meaning will follow from them.

Start with the five families and the order of precedence, because these two ideas let you work out most signs even when you do not recognise the pictogram at once. Then learn the common signs in each family, paying attention to their shape and colour.

Practise with questions that ask you to apply the precedence rule, for example when a traffic agent contradicts a traffic light, or when a temporary sign conflicts with a permanent one. Working through realistic examples is more useful than memorising pictures alone.

Revisit the catalogue after any major reform, because the RD 465/2025 changes mean some older study material may describe signs differently.

A simple method works well. Make a short list of each family, write one line on its shape and colour, and add the two or three signs you find hardest. Review that list for ten minutes a few times a week rather than cramming it in one session. Spotting the family first, then applying the precedence rule, is the habit that makes sign questions easier, whatever the exact wording.

• Learn the families by shape and colour before learning individual signs.
• Remember the five-step precedence order in Article 133 of the RGC.
• Treat traffic agents and temporary signs as the highest priority.
• Check the official catalogue wording before relying on memory.
