One-way street Switzerland: rules, priority & theory exam

Short answer — what applies on a one-way street?

For one-way streets in Switzerland (Einbahnstrasse), the theory exam mainly tests situational judgement: Do you recognise the permitted direction, the entry, the exit and possible bikes against the flow? This short answer is for skimming – the sections below cover basic rules, priority at junctions and typical traps.

• Only in the permitted direction: You may drive a one-way street only in the indicated direction. The other end typically shows “no entry” (Einfahrt verboten).
• No free U-turns: Reversing on a one-way street is generally not allowed – exam-wise exceptions mainly cover parking or coupling a trailer, not a shortcut against the flow.
• Priority still applies: A one-way does not automatically cancel junction and signal rules. Keep reading right-before-left and signals.
• Bikes are often a special case: Oncoming cyclists only when the one-way is released for them – otherwise the same direction duty applies.
• Right-hand traffic (RHT): All examples assume Swiss right-hand traffic – no left-hand-traffic framing.

What is a one-way street in the theory exam?

In the exam, “one-way street” is rarely a word game – it is a situation picture: recognisable one-way signing, vehicles only in one direction, often narrow in town, sometimes with released bike oncoming traffic. You read direction + entry/exit + junction, not only the keyword “one-way”.

Exam-wise the picture language is often enough: arrow direction, “no entry” at the other end, a vehicle entering the wrong way, or a bike coming towards you because (or although) the release is signed. Anyone who only sees “one lane” and forgets the direction duty misses the real question.

This deep-dive owns the one-way street itself. Stopping/parking and the full priority system stay in the linked articles – here you train direction, entering and typical one-way traps.

One-way vs ordinary street / oncoming traffic

• Ordinary street with oncoming traffic: Meeting is expected; you stay right, share space and treat oncoming traffic as normal.
• One-way street: Motor traffic basically flows in one direction only. The street is treated like the right half of a road open in both directions – exam-wise: think “one direction”, not “two carriageways against each other”.
• One-way with limited oncoming traffic: When cyclists are expressly released, it remains a one-way for cars – but you expect bikes against the car-arrow direction.

Mnemonic: one-way does not mean “no more rules”, it means “direction duty + other rules still apply”. Speed, distance and signals remain part of the picture.

Situation pictures — what the exam watches for

Exam-wise, scan in two seconds:

1. Direction: Which way is allowed? Is there “no entry” at the other end?
2. Entry / exit: May you enter here at all? How do you position for turning?
3. Junction / side road: Right-before-left or signals – the one-way does not erase that.
4. Bike: Is oncoming cycle traffic released? Then expect bikes early.

Signals and markings in words: Swiss traffic signs.

Driving on a one-way street — the basic rules

The exam core for driving on a one-way street: only in the indicated direction. Driving against the one-way or turning round fails the direction duty – whether or not “anyone is coming”. Train situation questions this way – without invented CHF fines and without sign artwork.

Use a checklist: (1) Is the permitted direction clear? (2) Am I at the correct end? (3) Am I planning a manoeuvre against the flow (U-turn, reversing through the one-way)? If yes–correct–no, you stay in the safe frame.

Entering and leaving

• Entering: Only where the one-way starts in arrow direction or entry is allowed. At the closed end, “no entry” applies – entering there is the classic disregard trap.
• Leaving / turning: Think indicators and lane choice. For a left turn you may often position further left on a one-way than on an ordinary two-way street – because no oncoming traffic “owns” the left side. Read the picture and markings.
• Obstacles / islands: At traffic islands and obstacles and past a moving tram you may pass left or right on a one-way – exam-wise: space and sight, not “always left” as a reflex.
• No U-turn as a shortcut: Drive the one-way, then turn and return against the flow – exam-wise wrong, even if you “did not see” the end signal.

Overtaking is another topic and often tricky on narrow one-ways – short link: Overtaking in Switzerland.

Stopping and parking only where allowed

On a one-way street: stop and park only where signing and markings allow it. Reversing is generally prohibited on one-ways – exam-wise exceptions mainly cover parking, coupling trailers and similar short manoeuvres, not “reversing along the one-way”.

Details on no-stopping, parking and markings do not belong in this deep-dive – they live in their own article: Stopping and parking in Switzerland. Here the bridge is enough: direction duty first, then parking logic.

Priority and junctions on a one-way street

Important boundary: the one-way mainly regulates direction of travel. It does not replace the priority system. That is why this article stays slim on right-before-left, roundabouts, pedestrians and tram – and deliberately links the overview. You should gain one-way depth without cannibalising the Vortritt article.

Right-before-left and signals — short

If you meet a junction or side road on a one-way, signals and general priority rules come first – typically right-before-left, unless signed otherwise. Classic misunderstanding: “I am on the one-way, so I always have priority.” Exam-wise wrong – read signing and right-before-left first.

When entering the one-way from a side road: who has priority? Read signals and right-before-left – one-way direction only says where traffic flows, not automatically who goes first. Signs: Swiss traffic signs; lights: Traffic lights in Switzerland; system: Right of way in Switzerland.

Do not rewrite the full priority system here

Right-before-left, roundabouts, zebra crossings, mountain roads, tram – those stay in the system and special articles. This deep-dive owns direction, entering, bikes against the one-way and one-way traps. Other special places only as links, e.g. Zebra crossings in Switzerland or Mountain road priority.

Bikes and cycles on a one-way street

Exam-wise and Switzerland-specific: bikes may ride against the one-way only when expressly released – typically via “one-way street with oncoming cycle traffic” (or a comparable release with symbol/wording). Without that release, cyclists have the same direction duty as motor vehicles.

• As a car driver: With released bike oncoming traffic, expect cyclists early – especially when entering, leaving and turning left. Think speed and lateral space; the street often “looks” like an ordinary one-way but is two-way for bikes.
• As a cyclist: Against the one-way only with clear release. No “shortcut against the arrow” just because the street looks empty.
• No automatic free-for-all: A cycle release does not mean motorcycles or cars may drive against the one-way.

Other special priority places (e.g. roundabouts) stay linked without expanding here: Roundabouts in Switzerland.

Note: Exam prep follows typical syllabus logic (SVG/ASTRA framing), not legal advice and not a substitute for official information.

Typical theory-exam traps

No copyrighted exam dumps – only exam-style rule explanations for one-way streets in Switzerland. Use the list as a training check: read each trap aloud with the picture in mind (direction, entry, bike, junction), then you decide more calmly under time pressure.

1. “May I enter at the no-entry end if the street is empty?” – No. The direction duty applies regardless of momentary traffic.
2. “Can I U-turn on the one-way and drive back?” – Exam-wise no as a shortcut against the flow. Reversing is generally prohibited; short parking manoeuvres are different from turning against the one-way.
3. “I am on the one-way – do I have priority at every side road?” – No. Signals and right-before-left first (system: right of way).
4. “Bikes are coming towards me – is the one-way invalid?” – Not automatically. Check whether cycle oncoming traffic is released; then expect bikes without driving against the car arrow yourself.
5. “Position fully left for a left turn – allowed?” – Often yes exam-wise, because no oncoming traffic occupies the left side; read markings and the picture, do not blindly stay centre.
6. “Disregarding the one-way – does ‘I missed the signal’ count?” – In exam logic, recognising the direction duty counts. Excuses do not replace the rule; we deliberately do not invent CHF fine amounts here.

How to practise one-way streets & priority online for free

Many errors come from treating “one-way” as a keyword instead of a picture. Goal when practising: stable pattern recognition – not memorising wording. In the simulation, check briefly:

1. Direction clear? – permitted travel direction and any no-entry at the other end
2. Manoeuvre against the flow? – U-turn, reversing, wrong entry
3. Junction / signal? – then general priority logic first
4. Bike release? – expect cycle oncoming traffic or not
5. Parking / stopping? – only where allowed; details in the parking article

Practise like this:

1. Start with the demo and filter situation questions.
2. Practise mixed sets under learn the theory test online free.
3. Move to full simulations via learn driving theory.
4. Light upsell if needed: packs & prices.

FAQ

May you turn round on a one-way street?
Exam-wise no as a free U-turn against the flow. Reversing is generally prohibited; exceptions mainly cover parking and similar short manoeuvres – not driving back against the one-way. Overview: Swiss traffic rules.

Who has priority when entering a one-way street?
One-way direction alone does not decide that. Read signals and right-before-left at the junction. System context: Right of way in Switzerland.

May bikes ride against the one-way?
Only when the one-way is expressly released for oncoming cycle traffic. Without release, the same direction duty applies. As a car, with release, expect oncoming bikes early.

What does the one-way signal mean in words?
It marks a street that may only be driven in the indicated direction. The other end typically shows “no entry”. Limited oncoming traffic (e.g. cyclists) is additionally signed – signal details: Swiss traffic signs.

Ready to solve one-way questions calmly?

Read direction, drive only the permitted way, do not turn against the one-way, check priority at junctions separately, expect oncoming traffic when bikes are released – that is the exam core for one-way streets in Switzerland. Pair with Swiss traffic rules, right of way, stopping & parking and traffic signs, and practise pictures. Stable judgement under time pressure cuts error points.
