This warning sign, code 155 and often called 'Riders', alerts you to potential hazards ahead on the road. In Iceland, this sign is crucial because it prepares you for conditions that could include poor visibility, loose surfaces, ice, or strong winds. When you see this sign, it's essential to reduce your speed early, improve your observation, and approach the area with extra care to ensure a safe journey.
This hazard warning sign signals upcoming danger requiring early speed reduction and heightened observation on Icelandic roads. Recognizing and interpreting this sign correctly is crucial for adapting to potential hazards and passing your theory test.
Riders is a hazard warning sign placed far enough in advance to let drivers adapt before reaching the danger. It does not by itself create a fixed manoeuvre, but it clearly signals that the road or traffic situation ahead needs earlier braking, steadier steering, and better lane discipline than an ordinary section of road. In practice, the right response is to finish major braking before the hazard, keep a smooth line through it, and avoid sudden reactions that could destabilise the vehicle. The warning is particularly important in Iceland because weather, darkness, snow, wind, and changing surfaces can make a familiar hazard much more severe.
This warning sign tells drivers that riders is ahead and that they need to reduce speed early, improve observation, and approach with extra care. On Icelandic roads that can mean preparing for poor visibility, loose gravel, ice, strong wind, narrow margins, or limited room to recover if something goes wrong.

The Riders sign (155) is a general warning that there is a hazard ahead. It doesn't specify the exact danger, but it indicates that you need to be more vigilant and prepared for conditions that might require slower speeds, careful steering, or a different road position. In Iceland, this often relates to unpredictable weather, road surfaces, or narrow sections.
Upon seeing the Riders sign (155), you should begin to reduce your speed well before you reach the hazard. It's also vital to increase your observation, looking further ahead for any developing risks, and ensure you maintain a stable position on the road, leaving a good safety margin.
A common trap is assuming the hazard is minor just because the road looks clear or quiet. Learners might also fail to brake early enough or make sudden movements within the hazard zone. The theory exam tests your understanding that this sign requires proactive preparation, not a last-minute reaction.
No, the Riders sign (155) is a warning sign, not a stop sign. It requires you to adjust your speed and approach with caution, but not necessarily to stop unless the situation ahead actually demands it. The key is to be prepared to stop or react appropriately if necessary.
Yes, you should avoid ignoring the warning and continuing at an unsafe speed. Harsh braking or abrupt steering inputs within the hazard area can destabilise your vehicle, especially on potentially slippery or uneven Icelandic roads. Taking an unstable line or assuming the road is safe because it appears quiet are also behaviours to avoid.
