What is a Road Intersection?

An intersection, also known as a junction, is a critical point in the road network where two or more roads converge, allowing traffic to change direction or continue straight. These areas are designed to facilitate movement between different routes but also represent a significant potential for conflict if drivers do not understand and apply the correct rules.

In Switzerland, intersections vary widely, from simple crossings in residential areas to complex multi-lane junctions in urban centers. Recognizing the type of intersection and its governing rules is the first step towards safe navigation.

Types of Intersections and Priority Rules in Switzerland

Swiss traffic law clearly defines how priority (right-of-way) should be determined at intersections. Understanding these types is vital for your theory exam:

• Uncontrolled Intersections: These intersections lack traffic lights or priority signs. In Switzerland, the general rule is 'priority to the right' (Rechtsvortritt). This means vehicles approaching from your right generally have the right-of-way, unless otherwise indicated by road markings or specific situations like tramways.
• Controlled Intersections: These are regulated by traffic lights, stop signs (Sign 3.01), or yield signs (Sign 3.02). Traffic lights override all other priority rules. If traffic lights are out of order, priority reverts to road signs, and if no signs, then to the 'priority to the right' rule or police direction.
• Intersections with Roundabouts: Roundabouts are special types of intersections. In Switzerland, vehicles already in the roundabout typically have priority over those entering, unless signage indicates otherwise. Always signal your exit from a roundabout.
• Intersections with Road Markings: In some cases, yellow diamond road markings or 'shark's teeth' lines on the road can indicate priority even without signs, often reinforcing the 'priority to the right' rule or indicating a yield situation.

Safe Approach and Navigation at Intersections

Approaching an intersection requires a high level of situational awareness and proactive decision-making. Here are key considerations:

• Observe and Anticipate: Scan the intersection well in advance, looking for signs, lights, other vehicles, pedestrians, and cyclists. Anticipate potential conflicts, especially when visibility is limited.
• Speed Adjustment: Reduce your speed when approaching any intersection, even if you have priority. This gives you more time to react to unexpected situations or errors by other drivers.
• Positioning: Position your vehicle correctly for your intended direction (straight, left, or right turn). Use appropriate lanes and maintain a safe following distance.
• Signaling: Always signal your intentions clearly and in good time, whether turning or changing lanes to prepare for a turn.
• Confirming Priority: Even if you have priority, be prepared to yield if another driver fails to observe the rules. Never assume other drivers will act predictably.

Common Theory Exam Questions and Pitfalls

Theory exam questions often test your understanding of priority rules at various intersections. Be careful with:

• 'Priority to the right' exceptions: Trams, emergency vehicles, and vehicles on a main road (indicated by signs) often have priority over the 'right-to-right' rule.
• Pedestrian crossings: At intersections, pedestrians crossing on a marked crossing (zebra crossing) always have priority in Switzerland, even if you have a green light for turning.
• Situational judgment: Questions might involve complex scenarios with multiple vehicles, requiring you to apply several rules simultaneously.

By diligently learning and practicing these concepts, you will be well-prepared for the intersection-related questions on your Swiss driving theory exam and for safe driving on the road.
