Navigating Iceland's single-lane bridges and tunnels requires understanding specific priority rules. This guide clarifies the 'car closer to the bridge has right of way' principle and the correct usage of passing places in tunnels. Mastering these concepts is vital for safe driving and for passing the Icelandic driving theory exam, ensuring you can confidently handle these challenging road situations.

Article content overview
Iceland's unique landscape presents drivers with specific road conditions, most notably numerous single-lane bridges, or 'Einbreið brú', and tunnels. These stretches of road, often found on the Ring Road and rural routes alike, require a clear understanding of priority rules to ensure safety and smooth traffic flow. Mastering these protocols is not only crucial for everyday driving in Iceland but also a key component of the Icelandic driving theory exam, assessed by Samgöngustofa. This article will guide you through the essential rules for single-lane bridges and tunnels, ensuring you can navigate them with confidence.
Single-lane bridges are a common feature across Iceland, and understanding the fundamental rule of right-of-way is paramount. The general principle for navigating an 'Einbreið brú' is straightforward: the vehicle that is closest to the bridge typically has the priority to cross first. This means if you are approaching a single-lane bridge and another vehicle is already on it or closer to it than you are, you must yield and wait for them to clear the bridge completely. This rule is designed to prevent head-on collisions and to manage traffic efficiently on these narrow crossings.
However, simply knowing the rule is not enough; practical application requires judgment and communication. While the closest vehicle has the right-of-way, it is always wise to slow down as you approach these bridges. Observe the other driver's intentions and speed. If you are both very close and unsure who has priority, a brief pause to assess the situation is far safer than rushing. In Iceland, drivers are generally courteous, but relying on courtesy alone is not a substitute for understanding and applying the official priority rules. Always be prepared to stop and wait if there is any doubt about who should proceed. The speed limit across these bridges is typically 50 km/h, so ensure you reduce your speed well in advance of your approach.
Iceland features several single-lane tunnels, particularly in the Westfjords and other mountainous regions, which often incorporate designated passing places, known as 'Mætingarstaður'. These are areas where drivers can pull over to allow oncoming traffic to pass safely. These passing places are typically marked with a sign, often a blue sign with a white 'P' for parking or 'M' for Mætingarstaður, or sometimes simply a clearly designated wider section of the tunnel. The Icelandic Transport Authority (Samgöngustofa) emphasizes proper etiquette and understanding of priority within these tunnels.
The general rule in single-lane tunnels with passing places is that the driver on the side where the passing places are located must yield to oncoming traffic. This means if you are driving in a tunnel and see a passing place on your right, and an oncoming vehicle is approaching, you should pull into the passing place to let them go by. If passing places are on both sides, the vehicle that arrives first at the designated passing area has priority. It is essential to be attentive to signage and the layout of the tunnel. If you are unsure, always err on the side of caution and prepare to stop.
A notable example of a modern, significant tunnel is the Vaðlaheiðargöng near Akureyri. This is a privately owned, tolled tunnel, and drivers must be aware of the payment system. While its length and design present similar considerations to other tunnels, the primary distinction for drivers is the toll requirement, which must be paid online within 24 hours of transit. The Icelandic Transport Authority ensures that all tunnels adhere to strict safety requirements, and monitoring systems are in place to detect and respond to any hazardous conditions swiftly, including closing the tunnel if necessary for emergency services.
On any narrow road, including single-lane bridges and tunnels, using your headlights is not just about visibility; it's a vital form of communication. In Iceland, it is mandatory to have your headlights on at all times when driving. This ensures that you are visible to other road users, especially in conditions of low light, fog, or when approaching blind corners or single-lane structures. When approaching a single-lane bridge or tunnel, keeping your headlights on clearly signals your presence and intent to other drivers, contributing to safer navigation.
Remember that in Iceland, headlights must be on at all times, regardless of the weather or time of day. This is a fundamental rule that aids visibility and communication on all roads, especially the narrow ones.
The Icelandic driving theory exam, administered by Samgöngustofa, often tests candidates on their understanding of these unique road infrastructure rules. Common exam questions might present scenarios where two vehicles approach a single-lane bridge or tunnel simultaneously, asking the applicant to identify who has priority. Learners often make mistakes by assuming a vehicle must always yield if it's on the right, forgetting that proximity to the bridge or the specific rules for passing places in tunnels are the determining factors.
Pay close attention to the wording of exam questions. They might describe a situation with a single-lane bridge and ask about the priority, or they might describe a tunnel with marked passing places and ask for the correct action. Understanding the terminology, such as 'Einbreið brú' and 'Mætingarstaður', is also beneficial. The exam aims to ensure you can apply these rules safely and effectively in real-world Icelandic driving conditions, preventing dangerous situations.
Never assume oncoming traffic will stop or yield. Always proceed with caution and be prepared to stop if necessary, especially when navigating single-lane bridges and tunnels. Your own safe driving practices are the ultimate guarantee of safety.
To succeed in your Icelandic driving theory test regarding single-lane infrastructure, focus on these core points:
By internalizing these rules and practicing how they apply in various scenarios, you will be well-prepared for both your theory exam and for confident, safe driving on Iceland's diverse roads.
Iceland's single-lane bridges ('Einbreið brú') require drivers to yield to the vehicle closest to the bridge, with a recommended speed of 50 km/h. Single-lane tunnels with passing places ('Mætingarstaður') obligate drivers on the side with designated passing areas to yield to oncoming traffic. The Vaðlaheiðargöng tunnel near Akureyri operates under standard tunnel rules but requires online toll payment. Headlights must be on at all times in Iceland for safety and communication, especially on narrow roads and bridges. These rules are commonly tested in the Samgöngustofa theory exam, where exam questions often present simultaneous approach scenarios requiring application of the proximity-based priority rule.
