This is a hazard warning sign, indicating that you are approaching an area where stones may be thrown onto the road. In Iceland, this hazard can be exacerbated by weather conditions, darkness, or poor road surfaces. You must reduce your speed early, improve your observation, and approach with extra care to maintain vehicle stability and safety.
This 'Stone Throwing' sign (112) requires early speed reduction and heightened awareness to navigate potential hazards safely. Mastering its interpretation is crucial for your Icelandic theory test revision and understanding traffic sign explanations.
Stone Throwing 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 stone throwing 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.
