When turning left in Sweden, accurately judging the speed and distance of oncoming traffic is paramount for safety and for passing your theory exam. This guide breaks down the decision-making process, focusing on how to anticipate hazards and maintain appropriate safety margins, directly aligning with Trafikverket's emphasis on driver awareness.

Making a left turn across oncoming traffic is one of the most common yet critical maneuvers a driver undertakes. In Sweden, as in many countries, this action demands a keen understanding of traffic flow, priority rules, and, crucially, the ability to accurately judge gaps in oncoming traffic. This skill is not only fundamental to safe driving but is also a significant focus of the Swedish driving theory examination, overseen by Trafikverket. Mastering how to assess oncoming vehicle speed and distance is essential to ensure a safe margin, preventing accidents and building confidence on the road.
The Swedish theory test places a strong emphasis on hazard anticipation and making informed decisions, especially in complex situations like left turns. Understanding when it is safe to proceed, when to yield, and how to correctly interpret the behaviour of other road users is paramount. This article will delve into the specific rules and best practices for judging gaps when turning left in Sweden, providing you with the knowledge needed to navigate these situations safely and confidently, and to excel in your theory test.
Turning left in Sweden requires a comprehensive assessment of the traffic environment. Unlike a right turn, a left turn necessitates crossing the path of oncoming vehicles, making it inherently more dangerous if not executed with proper care and foresight. Swedish traffic regulations, as interpreted by authorities like Trafikverket, prioritise safety above all else, meaning drivers must be proactive in anticipating potential hazards and ensuring they do not impede or endanger other road users. This involves a detailed understanding of how to evaluate the speed, distance, and potential trajectory of approaching vehicles.
The complexity is further amplified by varying road conditions and traffic densities. Urban environments, with their multitude of intersections, pedestrian crossings, and cyclist paths, present unique challenges compared to the higher speeds and longer sightlines encountered on rural roads, known locally as 'landsväg'. In all scenarios, the fundamental principle remains: a left turn should only be initiated when it is absolutely clear that it can be completed without causing any danger or unnecessary delay to other traffic.
A core principle governing left turns in Sweden is the 'svängningsregeln', or turning rule. This rule dictates that when you intend to turn left, you must give way to all oncoming traffic. Furthermore, you must also yield to pedestrians who are crossing the road you intend to turn into, as they are considered traffic users on the 'körbana' (roadway) you are about to enter. This means that even if you have a green light in some signalized intersections, you are still obligated to ensure your turn can be made safely and without hindering pedestrians.
The svängningsregeln also has implications for your positioning while waiting to turn. You must not obstruct oncoming traffic by driving too far forward into the intersection while waiting for a safe gap. This is crucial for maintaining the flow of traffic and preventing potential collisions. The intent is to allow you to complete your maneuver efficiently once a safe opportunity arises, without becoming an obstacle.
Judging a gap in oncoming traffic is a dynamic process that involves assessing multiple factors simultaneously. It's not simply about looking for a large empty space; it's about predicting the behaviour and speed of approaching vehicles and ensuring you have sufficient time to complete your turn. This requires a good understanding of how speed relates to distance and time. For instance, a vehicle that appears far away might be travelling at a high speed, closing the distance much faster than a slower-moving vehicle.
Swedish driving instruction and Trafikverket's guidelines emphasize the importance of 'uppsikt' (observation) and 'avsökning' (scanning). This means actively looking for traffic in all relevant directions, not just the most obvious ones. When preparing for a left turn, this includes looking left, right, straight ahead, and crucially, behind you, to be aware of any traffic that might be overtaking or approaching rapidly.
Several factors influence your ability to judge a safe gap for a left turn:
To ensure safety and comply with Swedish traffic law when making a left turn, a strategic approach is necessary. This involves not only observing but also acting decisively and correctly based on your observations. The Swedish theory exam frequently tests these decision-making processes, often presenting scenarios where precise timing and adherence to rules are critical.
In urban settings, left turns can be particularly challenging due to the high density of traffic, including cars, buses, trams, cyclists, and pedestrians. You must maintain a heightened awareness of your surroundings at all times. When planning a left turn, signal your intention early, and position your vehicle appropriately within your lane. Before entering the intersection, scan for oncoming traffic, pedestrians on cycle paths or sidewalks you will cross, and any signage that might affect your manoeuvre.
When you are at the intersection itself, your scanning pattern should be thorough. A common recommended sequence when approaching and entering an intersection to go straight or turn is to first look left (where traffic is often closest and most immediate), then straight ahead (to check for pedestrians or cyclists on the other side), then right (being prepared to yield if necessary), and finally, a concluding look to the left before proceeding. When turning left, this 'look left, look ahead, look right, look left again' approach is fundamental.
On rural roads, traffic generally moves at higher speeds, and visibility can sometimes be better, but the consequences of a misjudged gap are often more severe. The principle of yielding to oncoming traffic remains paramount. A common pitfall on rural roads is the temptation to rush a left turn when traffic appears sparse. However, it is essential to remember that vehicles can cover long distances quickly.
A significant hazard on rural roads when turning left is the risk of being hit from behind by a faster-approaching vehicle, especially if you have to stop to wait for a gap. To mitigate this, try to adjust your speed before entering the intersection so that you can glide through the turn without stopping, if possible. If you must stop, ensure your wheels are not turned to the left, as this would position your vehicle into the oncoming lane if you were struck from behind.
In situations where a direct left turn across oncoming traffic is particularly hazardous, Swedish roads may be designed with what is known as a 'spansk sväng' (Spanish turn). This is a safety feature where, instead of making a direct left turn, drivers are directed to turn right into a small side road or slip lane and then cross the oncoming traffic lanes from that position. This allows the driver to cross traffic one direction at a time, from a safer vantage point, and often with less conflict.
It is crucial to recognise signs indicating a 'spansk sväng' and to follow the designated route. These are often implemented after curves or crests of hills where visibility for a direct left turn is limited. The purpose is to significantly reduce the risk of accidents by eliminating the need to judge a single, large gap across two lanes of opposing traffic.
The Swedish driving theory exam is designed to test not just your knowledge of rules but your ability to apply them in practical, safe driving scenarios. When it comes to left turns, several common mistakes and exam traps exist:
Mastering the art of judging gaps for left turns is a cornerstone of safe driving in Sweden. It requires a combination of understanding the 'svängningsregeln', diligent observation, accurate assessment of oncoming traffic, and the patience to wait for a truly safe opportunity. By internalizing these principles and practising them conscientiously, you not only enhance your safety on the road but also equip yourself to successfully navigate the challenges presented in the Trafikverket theory examination. Remember, a safe left turn is one that is completed without compromising the safety of yourself or any other road user.
