Road signs explained

Swiss road signs used in the theory exam fall into three groups: regulatory signs (obligations and prohibitions), warning signs, and information signs. Regulatory signs are usually circular. Warning signs are triangular. Information signs are often rectangular. Shape is the first cue on a picture question: it tells you whether the sign orders you to act, warns you of a hazard, or only informs you.

Colour then splits those groups. A red border on a round sign typically marks a prohibition. A blue circular sign typically marks an obligation, such as a mandatory direction. Warning signs combine a triangle with a red border and a white background. Information signs are commonly blue or green rectangles. Colour supports the category; it does not replace reading the symbol.

These are the same categories you meet on Swiss roads. If a question shows several signs at a junction, identify each category first, then read how they apply to the road in the picture. Mixing the groups is a common error: a triangular warning does not itself tell you to stop or to give way.

Stop, give way, no entry, speed limits, no parking and mandatory direction signs appear frequently. Stop requires a complete halt before you continue, even if the road looks empty. Give way — the inverted red-and-white triangle — means other traffic has priority; you slow and wait if needed, but you do not always have to stop when the way is clearly free. No entry is the red disc with a white horizontal bar: you must not enter from that direction.

A speed-limit sign shows a number inside a red circle. It applies until another limit or an end-of-restriction sign. Mandatory direction signs are typically a white arrow on a blue circular background: you must follow that direction. No-parking and stopping restrictions often appear with a plate under the roundel; read the plate together with the sign.

Colours matter under time pressure: red often means prohibition or danger; blue often indicates obligation or information. Do not guess from colour alone. A red triangle that points up is a warning; a red triangle that points down is give way. Mixing those two is a classic exam error, even though both use red.

Our platform includes over 1,200 questions with sign images and clear explanations. Regular practice helps you recognise signs quickly on exam day. Mixed sets work better than one pictogram in isolation, because the exam shows signs in traffic — a give-way triangle by a side road, a speed limit at the start of a built-up area, a blue arrow at a junction.

When you open a question, look at shape first, then colour, then the symbol. That order matches the three categories above and reduces mix-ups between warnings, prohibitions and information. After the shapes feel automatic, run a full simulation so you still read signs correctly with the clock running.
