Lesson content overview
Turning at intersections and navigating roundabouts are fundamental driving skills crucial for safety and maintaining smooth traffic flow. This comprehensive lesson, part of your Comprehensive Swiss Driving Theory Course for Category B License, details the correct procedures, legal obligations, and best practices for these common maneuvers. Understanding these techniques is vital for preventing collisions and successfully passing your Swiss driving examination.
Every turn and roundabout negotiation involves careful observation, precise vehicle control, and clear communication with other road users. Misjudgments or errors in these situations are frequent causes of accidents. This chapter will equip you with the knowledge to execute turns and navigate roundabouts safely and confidently, building upon your understanding of basic road markings, signaling, and priority rules.
Safe and lawful execution of turns at intersections and roundabouts relies on several interconnected principles. These principles ensure predictability, minimize conflict points, and protect all road users.
Right-of-way (often referred to as 'priority' in Swiss regulations) is the legal privilege that determines which vehicle proceeds first at an intersection. Correctly identifying and adhering to right-of-way rules is fundamental to preventing collisions.
Traffic on a priority road has precedence over traffic entering from side roads. Priority roads are typically marked by specific signs, ensuring a smoother flow of traffic. Drivers on a priority road do not need to stop or yield unless indicated by a traffic light or a stop sign.
A yield sign (Geben Sie Acht / Cédez le passage) requires drivers to give way to traffic on the intersecting road, which is typically a priority road. This means you must slow down and be prepared to stop if necessary, allowing vehicles on the priority road to pass before you proceed.
A stop sign (Stopp / Stop) is the highest form of yield requirement. It mandates that drivers must come to a complete stop before the stop line, even if there is no immediate traffic. Only after ensuring the intersection is clear can you proceed safely.
In Switzerland, if an intersection is not controlled by traffic lights, signs, or road markings, the default rule of right-hand priority applies. This means you must yield to any vehicle approaching from your right. This rule is crucial in residential areas or smaller roads where signs may be absent.
Always double-check for signs and road markings first. Only when none are present does right-hand priority apply. Never assume priority; always be prepared to yield.
When approaching any intersection, your first step is to identify the priority rules in effect. This might involve:
Once priority is established, you can plan your turn, ensuring you yield to any traffic that has the right-of-way before proceeding. For example, when turning left across the path of oncoming traffic, you generally must yield to those vehicles unless a specific left-turn signal gives you priority.
Signaling is a fundamental aspect of safe driving, informing other road users of your intended actions. Proper use of turn indicators is a legal requirement and a critical safety measure.
Vehicle lights used to clearly communicate an intended left or right turn to other road users, including drivers, cyclists, and pedestrians.
Never use hazard lights to signal a turn. Hazard lights are for indicating a stationary hazard or emergency, not for turning.
Lane discipline is crucial for orderly traffic flow and preventing conflicts, especially at intersections. Selecting the correct lane for your intended turn is a key step in safe maneuver execution.
Many intersections feature dedicated lanes specifically marked for turning left or right. These lanes are typically indicated by arrows painted on the road surface and often separated by solid or dashed lines.
Some lanes may be used for both straight-through traffic and turning traffic (e.g., a lane marked with a straight arrow and a right-turn arrow).
Always check road signs and markings overhead or on the road surface well in advance to ensure you are in the correct lane for your intended direction. Changing lanes at the last minute or after crossing the stop line is dangerous and often illegal.
Beyond choosing the correct lane, precise vehicle positioning within that lane is essential for executing a turn safely and smoothly. This ensures you have enough room for the turn's trajectory without encroaching on other lanes or road users.
When preparing for a right turn, especially from a lane that also continues straight, position your vehicle closer to the right edge of your lane.
For a left turn, your positioning depends on whether you are in a dedicated left-turn lane or a mixed lane.
Speed adaptation is a critical skill for navigating turns safely. Entering a turn at an inappropriate speed can lead to loss of control, skidding, or an inability to stop for hazards.
A common mistake is assuming that a turn can be made at the posted speed limit. The speed limit is the maximum allowed under ideal conditions, not the recommended speed for all maneuvers, especially turns. Always adjust your speed to what is safe for the specific turn and conditions.
Roundabouts are designed to improve traffic flow and reduce the severity of collisions compared to traditional intersections. However, they require specific navigation skills, particularly regarding yielding and lane discipline.
The most fundamental rule for entering a roundabout in Switzerland is to yield to vehicles already circulating inside it.
In multi-lane roundabouts, selecting the correct lane before entry and maintaining lane discipline inside is crucial for safe and efficient navigation.
Signaling your exit from a roundabout is mandatory and vital for communicating your intentions to following drivers and pedestrians waiting to cross.
Failing to signal your exit from a roundabout can confuse other drivers, especially those waiting to enter, and can lead to unnecessary braking or collisions.
Adhering to the specific articles of the Swiss Traffic Regulations (Verkehrsregelverordnung, RVV) is not just good practice but a legal obligation for all drivers.
According to relevant RVV regulations, drivers must give a clear indication with the vehicle’s turn signals before commencing a turn. This applies to all road types and is crucial for allowing other road users to anticipate your actions. Failure to signal or signaling prematurely can result in legal penalties.
The RVV mandates that vehicles on a priority road always have the right-of-way. Approaching vehicles without priority must yield, stopping if necessary, to prevent collisions. This rule underpins the safe operation of countless intersections across Switzerland.
A specific RVV article governs conduct at roundabouts, stating that vehicles entering a roundabout must give way to traffic already circulating inside it, unless otherwise indicated by specific markings or signals. This regulation is fundamental to the smooth and safe operation of roundabouts.
For multi-lane roundabouts, the RVV stipulates that drivers must stay within their chosen lane while traveling inside the roundabout and generally must not change lanes before exiting. This rule promotes predictable vehicle paths and prevents side-swipe accidents.
When making a turn at an intersection, the RVV requires vehicles to begin the turn from the lane designated for that specific direction, unless lane markings permit a shared lane. This prevents cutting across lanes and ensures correct alignment.
Even if the posted speed limit is higher, the RVV requires drivers to reduce speed to a level that allows for the safe execution of a turn. This legal requirement accounts for the dynamic forces acting on a vehicle during a turn, which can lead to loss of control if speed is not adequately managed.
Even experienced drivers can sometimes make errors when turning or navigating roundabouts. Being aware of these common pitfalls can help you avoid them.

Safe turning requires flexibility. You must adapt your approach based on environmental factors, traffic density, and the presence of vulnerable road users.
Reduced Visibility (Fog, Heavy Rain, Snow):
Nighttime Driving:
Wet or Slippery Roads (Rain, Ice, Snow):
Heavy Traffic:
Vulnerable Road Users Present (Pedestrians, Cyclists):
Vehicle Load (Heavy Trailer or Load):
Let's look at a few common driving situations to reinforce the application of these rules.
You are at an urban intersection, signaling a left turn. The traffic light is green, but there is oncoming traffic approaching and a pedestrian waiting to cross the road you intend to enter.
You are approaching a double-lane roundabout and intend to take the third exit. There's a car already circulating in the inner lane of the roundabout.
You are at a rural T-junction without any signs or traffic lights, intending to turn right onto the main road. A vehicle is approaching from your right on the main road.
Mastering turns and roundabout navigation is a cornerstone of safe driving. Here’s a concise summary of the key takeaways:
This lesson covers the essential procedures for turning at intersections and navigating roundabouts under Swiss traffic law. Learners must understand that right-of-way is determined by signs, markings, lights, or right-hand priority as a default. Correct signaling (early activation and exit signaling for roundabouts) and proper lane selection before reaching the intersection are critical for safety and exam success. Roundabout navigation requires yielding to circulating traffic, selecting the correct entry lane based on your intended exit, maintaining lane discipline throughout, and signaling your exit. Speed adaptation is mandatory regardless of posted limits, with additional caution required in adverse weather or heavy-load conditions.
A short set of high-value points that capture the most important learning from this lesson.
Right-of-way at Swiss intersections is determined by traffic signs, road markings, traffic lights, or default right-hand priority when nothing else applies.
Turn indicators must be activated early (30m urban, 50-100m high-speed), remain on throughout the maneuver, and signal right before your roundabout exit.
Lane selection must be made well before the intersection; turning from the wrong lane or changing lanes inside a roundabout creates serious collision risks.
Approaching vehicles must always yield to circulating traffic already inside a roundabout, and lane discipline must be maintained until after exiting.
Speed must be reduced before any turn regardless of posted limits, with further reduction needed for wet, icy, or heavy-load conditions.
Explore all units and lessons included in this driving theory course.
In uncontrolled intersections without signs or lights, right-hand priority applies: yield to vehicles approaching from your right.
For multi-lane roundabouts: use outer lane for first or second exit, inner lane for third exit or beyond.
Position right turns closer to the right edge of the lane; position left turns toward the center line or center of a dedicated left-turn lane.
Never change lanes inside a roundabout; once you enter in your chosen lane, stay in it until your exit.
The speed limit is the maximum under ideal conditions, not the safe speed for executing turns or navigating roundabouts.
Late signaling: activating turn indicators too close to the intersection leaves other road users insufficient time to react.
Turning from the wrong lane: attempting turns from lanes marked only for straight-through traffic causes conflicts and is illegal.
Failing to yield to circulating traffic: entering a roundabout without checking for vehicles already inside creates high-risk collision situations.
Lane changing inside roundabouts: switching between inner and outer lanes while circulating is prohibited and extremely dangerous.
Not signaling the exit: forgetting to activate the right indicator before your exit from a roundabout confuses following drivers and pedestrians.
