Topic 6
Traffic signs & road installations
Shape and colour give the meaning away before you have read the picture.
In short
Topic 6 turns memorising signs into a system. Warning signs are triangular with a red border. Regulatory signs are round: they order or forbid. Informative signs are rectangular and mostly blue. On top of those come the small plates underneath, which restrict or extend everything above them, and the markings and installations on the road itself — beacons, cones, barriers.
In roadworks
Yellow markings override white ones. Where roadworks reorder the lanes, the old white line has no meaning at all, however clearly it can still be seen.
What this topic teaches you
The first step is the classification, because it is what makes recognition at speed possible at all. A triangle with a red border is always a warning: something is coming, prepare for it, but nothing is forbidden. A round sign is binding — red-bordered it forbids, filled blue it prescribes. Rectangular and blue means information or direction. Anyone who separates those three forms reliably has answered half the test question before reading the symbol.
The second step is the small plates, and they are the most common reason for wrong answers. A white rectangle under the sign can limit its effect to certain vehicle types, times, days or distances — or extend it explicitly. A no-stopping sign with „werktags 7–19 Uhr“ underneath is not one on a Sunday morning, and a plate reading Anlieger frei changes who is meant in the first place.
The third step is everything painted on the road rather than standing beside it: solid and broken lines, hatched areas, stop lines, bicycle symbols, lane arrows. Markings are traffic signs, not suggestions. Add the installations from roadworks — beacons, warning lamps, barriers — which tell you where traffic is being led right now, even where the old markings are still visible.
- Triangle warns, circle orders, rectangle informs
- Small plates change the meaning completely
- Markings are binding, not decorative
- Yellow beats white in roadworks
What it looks like in Düsseldorf
Düsseldorf is a city of small plates. Around Pempelfort, Derendorf and Flingern almost every no-stopping sign carries a resident-parking plate with times; on the Königsallee and in the Altstadt plates govern delivery windows; on the main axes they separate bus lanes that taxis or cyclists may sometimes use. Reading only the big sign means reading half of it.
The second Düsseldorf peculiarity is cycle traffic on the carriageway. A Radfahrstreifen with a solid line is off limits to cars; a Schutzstreifen with a broken line may be crossed in exceptional cases but never used for parking. The difference is a single type of line — and in daily driving it is the difference between driving correctly and a cyclist having to swerve.
What the test does with it
The theory test shows you signs singly and in combination. Singly it asks about meaning; in combination it is nearly always about the small plate, or about where a sign starts applying and where it stops. A stretch-based prohibition ends at the next junction unless something says otherwise — one of those rules you have to understand properly once and then never get wrong again.
The practical test asks nothing and assumes everything. A missed give-way sign, a Radfahrstreifen driven over or a lane marking ignored are ordinary sources of error. The examiner also expects you to react to a sign before you reach it, not after.

- Reading the small plate first
- Where a sign starts and where it ends
- Not driving or parking on a Radfahrstreifen
Common questions
How do I tell whether a sign warns or forbids?
By its shape. Triangular signs with a red border warn of a hazard and forbid nothing. Round signs are binding: red-bordered they forbid, filled blue they prescribe. Rectangular, mostly blue signs give information.
How far does a traffic sign apply?
Unless something says otherwise, a stretch-based prohibition applies until the next junction or side road. A small plate can state the length, mark the end explicitly, or restrict the effect to certain times and vehicle types.
May I drive on a Schutzstreifen for cyclists?
Only in exceptional cases and only where no cyclist is endangered — a Schutzstreifen is marked with a broken line. A Radfahrstreifen with a solid line may not be driven on, stopped on or parked on at all.
Do I really have to learn every sign by heart?
No, you have to learn the system. Anyone who reliably assigns shape and colour and knows how the small plates work can work out a sign they rarely see. The rest comes with driving, because you pass every important sign in Düsseldorf several times per lesson.
