Italian road signs — a guide to reading them
Last updated: · ✓ Checked against its sources
The classification below comes from the Italian highway code. The signs’ appearance, names and meanings were checked against the Ministry’s own published exam question bank and its sign images. Last verified: 29 August 2026. A large part of the theory exam is recognising these signs — get the shape and colour first and half the work is done.
There is a simple method for Italian road signs: read the shape and colour first, then the picture inside. The shape and colour alone tell you what kind of sign it is — a warning, an instruction, or just information.
The three categories
Italian law divides vertical signs (segnali verticali) into three categories — pericolo, prescrizione and indicazione. The small panel underneath a sign is none of the three; it is a separate thing called a pannello integrativo, and it has its own section below.
1. Segnali di pericolo (danger warnings)
Shape: an equilateral triangle with one vertex pointing up. Red border, white background, black symbol inside.
Something dangerous is ahead — slow down, pay attention. These are warnings, not orders.
⚠️ One exception to remember: where roadworks (cantiere) are in progress, the same danger signs are mounted on a yellow background, and the official question bank asks about this directly. A danger sign’s background can be white or yellow — the shape is the reliable marker.
Examples: dangerous bend (curva pericolosa), a rise in the road (dosso), a dip in the road (cunetta), pedestrian crossing ahead (attraversamento pedonale), roadworks (lavori in corso), level crossing ahead (passaggio a livello), slippery road (strada sdrucciolevole).
⚠️ Do not confuse dosso and cunetta — the exam sets questions specifically to catch this.
- Dosso — the road rises and then falls. The black symbol bulges upward. In the Ministry’s question bank the statement that this sign warns of “a rise, followed by a descent” is marked true, and the statement that it means cunetta is marked false. The same bank marks visibility as limited there, stopping and parking as prohibited, and overtaking as prohibited on the rising stretch of a two-lane, two-way road.
- Cunetta — the opposite: the road dips. The symbol sags downward. In rain, water, mud and debris collect there.
2. Segnali di prescrizione (prohibition, obligation and priority)
Shape: usually circular. Prohibitions have a red border; compulsory instructions are a white symbol on a blue background. The STOP and give-way signs have their own shapes, set out below.
⚠️ The reliable marker of a prohibition is the red border, not the colour inside. Divieto di sosta and divieto di fermata are both prohibition signs, and both are blue inside, with a red border and red bars.
Prohibitions (divieto) — examples:
| Sign | What it means |
|---|---|
| Divieto di transito | No vehicle may enter, from either direction — white disc, thick red border, nothing inside |
| Senso vietato | No entry from this direction (the wrong end of a one-way street) — solid red disc, white horizontal bar across the middle |
| Divieto di sorpasso | No overtaking |
| Limite massimo di velocità | Speed limit — white disc, red border, black number inside |
| Divieto di sosta | No parking — blue disc, red border, one red diagonal bar |
| Divieto di fermata | No stopping at all, not even briefly — blue disc, red border, two red bars crossing in an X |
⚠️ The first two are the ones most often confused, so here they are separately. Both are round, both have red in them, and they are not the same thing:
- Divieto di transito — white and empty inside, just the red border. No vehicle may enter this road from any direction, and the sign is posted at both ends of it. Pedestrians may pass — but not bicycles, because a bicycle is a vehicle.
- Senso vietato — solid red inside with a white bar across the middle. You may not enter from this direction, but the road is not closed: traffic comes the other way, because it is one-way.
An easy way to hold it: white inside means the road itself is closed; red inside means only your direction is closed.
⚠️ Sosta and fermata are different too, and not knowing the difference costs money.
- Sosta means leaving the vehicle. Fermata means a brief halt — dropping someone off, picking something up. Where fermata is prohibited, sosta is prohibited too; not the other way round.
- Divieto di sosta (one diagonal bar) — according to the official question bank, on urban roads this applies from 08.00 to 20.00, unless a panel underneath says otherwise.
- Divieto di fermata (two bars crossing) — this applies 24 hours a day, day and night, inside built-up areas as well. Not even a minute’s halt.
(The official names of these two signs are divieto di transito and senso vietato, and those are the names the exam uses.)
Compulsory instructions (obbligo) — examples:
| Sign | What it means |
|---|---|
| Direzione obbligatoria | You must go in the direction shown (arrow) — blue disc, white arrow |
| Rotatoria | Roundabout ahead, travel in the direction of the arrows — blue disc, three white arrows |
| Pista ciclabile | Cycle path — bicycles use this |
| Percorso pedonale | A route reserved for pedestrians |
| Catene per neve obbligatorie | You may not proceed without chains or winter tyres |
Two notes on that table, because both are examined:
- The first sign’s official name is direzione obbligatoria, and that is the name used throughout the Ministry’s bank of 7,139 questions — it is the name you will meet in the exam.
- The chains sign covers chains and winter tyres alike. According to the official question bank, this sign is satisfied by chains or winter tyres (pneumatici invernali) — either one.
Priority (precedenza) — different shapes:
| Sign | Shape | What it means |
|---|---|---|
| Fermarsi e dare precedenza (STOP) | Octagon, red, white “STOP” | You must come to a complete stop, then look and proceed |
| Dare precedenza | Inverted triangle, red border, white inside | Give way, stopping if necessary |
| Diritto di precedenza | Yellow diamond, white border | You have priority on this road |
| Intersezione con diritto di precedenza | Triangle, red border, black cross inside — the vertical bar is thick, the horizontal one thin | A junction ahead where you have priority |
The STOP sign’s official name is fermarsi e dare precedenza, and that is the name the exam uses.
3. Segnali di indicazione (information and direction)
Shape: usually rectangular.
The colour tells you what kind of road it is — and that is exactly what the exam asks:
- Green background → autostrada (motorway).
- Blue background → strade extraurbane (ordinary roads outside built-up areas).
Examples: parking (parcheggio — blue, white “P”), hospital (ospedale), limited traffic zone (ZTL — Zona a Traffico Limitato, restricting vehicles in town centres), dead end (strada senza uscita).
⚠️ The blue circular ROTATORIA sign is not in this group — it is a segnale di obbligo. The Ministry’s question bank marks it as obbligo, and it is in the obbligo table above. (There is also a separate triangular danger sign for a roundabout, CIRCOLAZIONE ROTATORIA. One subject, three different signs — and which is which is the question.)
Pannello integrativo — the small panel under a sign
Shape: a small rectangle mounted below the main sign. It makes the main sign’s meaning more specific — how far ahead the hazard starts, how far the rule runs, which vehicles it applies to, at what times.
The same panel means different things depending on the sign above it, and that is the exam question:
- “150 m” under a danger sign → the hazard starts 150 metres from the sign.
- “150 m” under a prohibition or obligation sign → the rule starts 150 metres ahead.
- “150 m” under a direction sign → the place is 150 metres further on.
⚠️ “Segnali complementari” does not mean this panel. In the law, segnali complementari are something else entirely — the delineatori placed to mark the edge of the road and its curves, posts and reflectors. The Ministry’s question bank keeps them in two separate chapters as well: segnali complementari in one, pannelli integrativi in another.
Why this is worth memorising
Theory questions often show a picture of a sign and ask what it means or when it applies. Even more often they ask which category it belongs to — pericolo, prescrizione or indicazione. Recognising the shape and colour first gets you half the answer before you have interpreted the picture at all.
Where the information on this page comes from
The classification of the signs comes straight from the law — which sign belongs to which category is written in the highway code itself.
The signs’ appearance and meaning were checked against the Ministry’s own published exam question bank and its sign images. That is an official publication, and the exam you will sit is drawn from that bank — but it is an answer key, not a statement of law. So the descriptions above are “how the exam shows the sign”, not “how the law says to draw it”.
This list is a selection of the most common and most important signs, not a complete one. For the complete set, use the official quiz question bank or your autoscuola’s materials.

Sources
Classification — from the law itself. The three categories of vertical sign are in art. 39 of the Codice della Strada, and the definition of segnali complementari in art. 42. Both were checked against two independent legal sources:
The regulation — DPR 495/1992. The triangular shape of danger signs is in art. 84; the definition of the panel underneath in art. 83; the official names of prohibition signs in art. 116; the names of obligation signs and the classification of rotatoria in art. 122; the STOP sign’s name in art. 107.
Appearance and meaning — the Ministry’s own question bank. Every sign’s image, name and meaning above was checked against the images and answer key of the official question bank published on the Portale dell’Automobilista.
