Road signs, markings and signals
Sign families
- Warning signs: red-bordered triangles (e.g. blind crest, sheep, single-lane bridge "Einbreið brú").
- Regulatory: red circles (speed, no entry "Innkeyrsla bönnuð"), blue circles (mandatory direction).
- Information: blue rectangles.
- Yield (give way) is an inverted triangle; Stop is an octagon.
- Supplementary plates give distance or apply the sign to a specific vehicle type.
- Markings: white edge and centre lines; yellow markings indicate temporary roadworks and override white.
Signals
- Flashing amber at a crossing = proceed only if no pedestrian.
- Solid red = stop behind the line.
- Green arrow gives protected movement.
- A police officer's signals override lights and signs.
Worked example
You approach a junction with a give-way sign and, below it, a plate showing a lorry symbol. The plate means the sign applies to lorries; you still follow the ordinary right-hand rule if no other sign applies to you. Many candidates misread the plate as "lorries have priority".
Traps
Icelandic text signs are part of the sign, not decoration; treating a warning triangle as a prohibition; ignoring temporary yellow markings in roadworks; assuming a flashing amber means stop.
