At speed you register a sign's shape and color before you read anything on it. Shape tells you the message class, and the class tells you what to do. Our traffic signs guide stores 52 entries, and every one belongs to exactly one of four shapes.
What each shape means
Four shapes carry four jobs, with counts computed from the dataset:
- Triangle, 18 entries, warns of a hazard ahead.
- Circle, 16 entries, regulates. A red ring forbids, a blue field commands.
- Rectangle, 16 entries, informs about facilities and road features.
- Diamond, 2 entries, grants priority.
The tool's rendering makes the class visible before you read the name. Prohibition circles get a red border with a diagonal slash. Warning triangles get a red border. Information signs render as a blue board. Priority diamonds render in amber.
The 16 warning triangles
The warning group covers the hazards on ordinary roads. The dataset holds both curve directions and the double curve, both level crossing types, barriered and unbarriered, pedestrian and school crossings, slippery road, loose gravel, steep descent and steep ascent, narrow bridge, side wind, animal crossing, traffic lights ahead, and vehicle entry from a side road.
Each description carries an action. Reduce speed on the curves. Avoid sudden braking on the slippery road. Use a low gear on the descent. Keep distance where vehicles can throw gravel.
Two entries deserve a second look during study. Side Wind marks an area with a danger of strong crosswinds, which matters for high sided vehicles and motorcycles. Animal Crossing tells you wild animals are likely to cross, so the correct response is care and lower speed over a stretch of road, and a single point.
Circles: 11 prohibitions and 5 commands
The prohibitory group holds two kinds of circle. Eleven entries forbid something: stop, yield, no entry, speed limits of 50 and 30, no overtaking, no parking, no stopping, no horn, no trucks, and no motorcycles. Five entries command a direction: straight ahead, left, right, pass on both sides, and a minimum speed of 30.
Note the speed trio. A maximum of 50 and a maximum of 30 sit beside a minimum of 30 in the same group, and exam questions target exactly that symmetry.
The priority group adds two more marked entries, the triangle yield sign and the stop sign, which brings the marked total to 13. The dataset stores its stop entry under the triangle shape and names it Stop (Octagon), because the entry models the sign concept rather than strict geometry. One honest accounting note: yield and stop each appear twice, once in the prohibitory group and once in the priority group, so the 52 entries describe 50 distinct signs.
Rectangles inform, diamonds grant priority
The 16 information entries mark facilities: motorway start and end, dual carriageway, first aid, filling station, hotel, restaurant, parking lot, telephone, breakdown service, repair shop, tunnel, bridge, pedestrian crossing, cycle path, and disabled parking.
The two diamond entries define who goes first. Priority road gives you the right of way at intersections, and its counterpart ends that right. Amber diamond is the fastest read on the board.
How the search behaves
1. Type a word into the search field.
2. The tool matches it as a case insensitive substring against every entry's name and description.
3. Results draw from all four categories at once, so a query for crossing returns the warning triangles, the school crossing, and the information rectangle together.
4. Switching tabs clears the query.
Two worked queries, computed from the dataset. The word crossing returns 7 entries, the five warning triangles that mention a crossing, the information pedestrian crossing, and the Bridge rectangle, whose description reads bridge crossing ahead. The number 30 returns exactly 2 entries, Speed Limit 30 and Min. Speed 30, one maximum and one minimum in the same result set.
One quirk is worth flagging because we verified it in the source. The result count line is written in Turkish in every language, so an English visitor sees a Turkish counter above English results. Names and descriptions localize correctly, only the count line does not.
Limits for exam preparation
The dataset holds 52 entries based on the Turkish catalog, with English, German, Spanish, and Italian translations. National catalogs differ in details, and 52 covers the core set, with no road works signs and no country specific motorway variants. The drawings are schematic shapes rather than photographs of real boards. Use the tool to learn categories and names, then confirm against the official catalog for your country before your exam.
Checklist for study sessions
- [ ] Learn the four shape classes before memorizing single signs.
- [ ] Drill the two maximum speeds against the minimum speed entry in the same group.
- [ ] Search one concept, like crossing, to pull matches from all four categories.
- [ ] Count each run: 16 warnings, 16 circles, 16 rectangles, 4 priority entries.
- [ ] Confirm national variants against your official catalog.
Study the full set in the [traffic signs guide](/en/traffic-signs). If your national exam includes a sign missing from the 52, send its name, group, and what your catalog says, because the dataset grows from what readers are actually tested on.
