Switzerland Driving Rules 2026: Speed, Alcohol, Lights

Swiss driving rules: a quick orientation

Switzerland has some of the strictest road rules in Europe and some of the highest fines. The headline numbers are familiar to anyone who has driven in Germany or Austria: speed limits 50/80/100/120 km/h, alcohol limit 0.5 g/L, daytime running lights required. The cultural difference is in enforcement. Swiss police stop cars frequently for routine checks, automated cameras are everywhere on motorways and city limits, and fines are calibrated to be felt: a flat CHF 600 for the cheapest drunk-driving conviction is the price of a serious deterrent.

For the visitor, four things matter: pay the vignette before joining a motorway, keep dipped headlights on at all times, respect the speed limits literally, and do not drive after drinking. Everything else is conventional European traffic law.

Speed limits

Many city districts and most school zones display 30 km/h limits. Switzerland enforces these strictly: a camera-issued ticket for 12 km/h over the 30 in a residential street typically costs CHF 120.

Variable speed signs reduce the limit dynamically in tunnels, bad weather and heavy traffic. The legal limit is whatever the matrix sign currently shows. Speed cameras in tunnels usually enforce the displayed limit; in the Gotthard tunnel the 80 km/h cap is enforced by section control (Streckenkontrolle) along the full 17 km.

Section control

Switzerland uses section-control speed cameras on the busiest tunnel approaches and on some motorway sections. The system measures average speed over a distance rather than instantaneous speed. Slowing for the first camera and accelerating between cameras does not work. Section controls are signposted before the section starts (white sign with two cameras and the distance in km).

Daytime running lights

Dipped headlights or DRL must be on whenever the car is moving, day or night, regardless of weather. The rule applies to motorcycles, cars and trucks. The fine for driving without lights during the day is around CHF 40, often issued on the spot at a routine check.

Modern cars do this automatically. Older cars and rental cars that do not should have the parking-light or low-beam switch flipped before joining any public road.

Alcohol and drugs

The standard limit is 0.5 g/L blood alcohol. For specific groups the limit is effectively zero (0.1 g/L, which is below the threshold from food fermentation):

• New drivers: first 3 years of licence
• Professional drivers: truck, bus, taxi, driving instructors
• Learner drivers
• Drivers carrying passengers under 16 (recommended, not always mandatory)

Fines escalate steeply:

Driving under the influence of drugs follows the same procedure with saliva testing on the roadside.

Mandatory equipment

The Swiss list is short:

• Warning triangle: must be carried inside the car, accessible without opening the boot. Place 50 m behind a broken-down car on rural roads, 100 m on motorways.
• Vehicle documents: licence, registration (Fahrzeugausweis), insurance proof (green card no longer required for EU/EEA drivers since 2021 but still recommended for non-EU visitors).
• Spare tyre or repair kit: required for vehicles registered in Switzerland, recommended for visitors.

What is NOT legally required in Switzerland but is in neighbouring countries:

• High-visibility vest (recommended; mandatory in France, Italy and Austria)
• First-aid kit (recommended; mandatory in Germany and Austria)
• Spare bulbs (recommended)
• Snow chains (only required where the sign is posted)

The pragmatic approach is to carry the full Austrian / German / Italian kit because you will probably drive into one of those countries on the same trip.

Winter driving

Winter tyres are not legally mandated. The legal test is whether your vehicle is “in a condition appropriate to the road conditions”. A summer tyre on snow fails that test, exposing you to liability for any accident and possibly criminal charges for negligence.

In practice, every Swiss resident switches to M+S or 3PMSF marked tyres from November to April. Visitors driving in winter should do the same or rent a car that is already winter-equipped. Major rental agencies (Hertz, Avis, Europcar, Sixt) include winter tyres on Swiss-based rentals as standard from November.

Snow chains are mandatory on roads where the round blue chain sign is displayed. Typical locations: alpine pass approaches in heavy snow, the A13 around the San Bernardino tunnel approach, the A2 south portal of the Gotthard in extreme conditions, and many cantonal roads in the Grisons, Valais and Bern Oberland.

Chains must go on the driven axle:

• Front-wheel-drive car: chains on front
• Rear-wheel-drive car: chains on rear
• 4WD car: chains on all four (some manufacturers specify rear-only)

Fitting chains is faster on a flat surface in advance than on the side of an icy road; practice once in the driveway before the trip.

Mobile phones and headphones

Holding a phone while driving is prohibited. The fine is CHF 100 on the spot. The phone can be in a cradle attached to the dashboard or windscreen for navigation and music; Bluetooth, Apple CarPlay, Android Auto and similar systems are fine.

Wearing headphones or earbuds while driving is explicitly forbidden by article 30 of the Verkehrsregelnverordnung (VRV). The rationale is hearing emergency vehicles, horns and other traffic. The fine is CHF 60. Hearing aids are obviously permitted; one-ear Bluetooth earpieces sit in a grey zone but police can fine for them.

Right of way and roundabouts

• Right has priority by default at unmarked intersections, including in cities. Look out for cars coming from the right on side streets.
• Yellow diamond sign (Vortrittsstrasse): you are on a priority road; oncoming and side-street cars must yield.
• Yellow diamond with black bar: end of priority road.
• Roundabouts: traffic already in the roundabout has priority. Indicate when you leave the roundabout, not when you enter.
• Trams have absolute priority in all situations. Never block a tram lane.

Overtaking rules

• Pass on the left on multi-lane roads. Right-side passing is prohibited and heavily fined.
• Indicate before pulling out and before returning to the right lane.
• No overtaking at level crossings, pedestrian crossings, intersections without traffic lights, or where the centre line is solid.
• School buses with flashing yellow lights: pass at reduced speed and stay alert for children.

Children and seat-belts

• Seat-belts mandatory for all occupants
• Children under 12 years or under 150 cm tall: car seat appropriate to age and weight, approved to ECE R44 or R129/i-Size
• Child in the front seat: only allowed if no airbag is active or the airbag is deactivated for that seat
• Maximum number of passengers: equal to the number of seat-belts

Roadside checks and fines

Swiss police can stop any vehicle at any time without specifying a reason. Routine roadside checks (Kontrolle) involve: licence and registration check, vehicle equipment check (lights, tyres, mandatory equipment), occasionally a breath test for the driver, and rarely a luggage check.

Fines:

• On-the-spot tickets (Ordnungsbussen): cash or card, fixed-amount, no court process. Examples: no lights CHF 40, mobile phone CHF 100, 11-15 km/h over the urban limit CHF 250.
• Mandate procedure (Strafbefehl): for more serious offences, fines tied to income (day fines, Tagessatze). A high-earning driver doing 30 km/h over the limit on a motorway can face fines in the thousands of CHF.
• Court procedure: serious cases with licence withdrawal, criminal record and possible prison sentences for extreme speeding.

Foreign-registered drivers pay on the spot if police request it. Refusal can lead to vehicle impoundment. Switzerland has reciprocal enforcement agreements with most EU countries, so unpaid tickets are pursued across borders.

Emergency corridor (Rettungsgasse)

Since 2021 Switzerland legally requires drivers to form an emergency corridor (Rettungsgasse / couloir de secours / corsia di soccorso) whenever traffic on a motorway or expressway slows to a standstill. The rule mirrors the German and Austrian systems and applies before emergency services arrive.

• Two-lane motorway: the left lane moves left, the right lane moves right, leaving a gap in the middle.
• Three-lane motorway: the left lane moves left, the middle and right lanes move right, leaving the gap between the leftmost and middle lanes.
• Timing: form the corridor as soon as traffic starts backing up, not after ambulances or police arrive. The whole point is that emergency vehicles reach the front of the queue without weaving.
• Do not use the hard shoulder: it stays reserved for genuine emergency use. Driving on the hard shoulder to bypass congestion is a serious offence (CHF 250 minimum).
• Fines for not forming: CHF 250 for private cars, CHF 500 for HGVs. Repeat offenders may see their licence suspended.

The Rettungsgasse is briefly explained on variable message signs when a Level 2 incident is active, but the requirement stands even without a visible reminder.

Mountain driving specifics

Alpine roads have their own etiquette and enforcement patterns that catch out first-time visitors used to flat-country driving.

• Uphill has right of way: on narrow mountain roads (single lane or one-and-a-half lanes), traffic climbing has priority over traffic descending. The descending vehicle must reverse to the nearest passing bay.
• Postal buses (Postauto) always win: yellow long-distance buses have absolute right of way on mountain roads. They signal with a distinctive three-note horn (“Ta-ta-ta”) on blind corners; when you hear it, pull over immediately.
• Use engine braking on descents: brake overheating is the leading cause of accidents on descents like the Sustenpass and Grimsel. Downshift to second or third gear and let the engine hold your speed instead of riding the brake.
• Altitude effects: petrol engines lose roughly 10% power per 1,000 m of elevation. Overtaking at 2,000 m needs more distance than at sea level. Diesel and turbocharged engines are less affected.
• Tunnel etiquette: keep 100 m to the vehicle in front (visible tunnel markers help). Switch off cruise control and full-beam headlights. Ventilation fans and speed limits are enforced by section-control cameras.
• Snow chains obligation zones: signposted with a blue circular chain symbol; obligation applies until an “end” sign or altitude threshold. Rental chains are available at TCS border stations for CHF 30-50 per week.
• Fuel and services: petrol stations above 1,500 m are rare and 20-30% more expensive than valley prices. Refuel before starting a pass ascent.

Winter overnight temperatures on high passes can drop 15 to 20 degrees below the valley figure; even in summer, keep an emergency blanket in the boot for alpine trips.

Rest breaks for professional and long-distance drivers

Switzerland enforces EU-aligned driving-time rules for HGVs and coaches, and the same limits are recommended (though not required) for private drivers who tackle long transits.

• Professional drivers (over 3.5 t or 9+ passengers): maximum 4h 30min continuous driving, then a 45-minute rest. Daily driving limit 9 hours (extendable to 10 hours twice per week). Weekly limit 56 hours; two-weekly 90 hours.
• Split rest option: the 45-minute break can be split into 15 minutes plus 30 minutes, in that order.
• Digital tachograph: mandatory on HGV/coach; Swiss authorities audit against the same rules as the EU. The tachograph card is required to be presented at any roadside check.
• Private car recommendation: TCS and ADAC recommend the same 4h 30min rhythm; motorway rest areas (Raststatte) are spaced every 30-50 km with picnic areas, coffee and toilets.
• Camper van and motorhome: rest breaks are unregulated for private use but heavily encouraged for alpine transits, where reaction times matter more than on flat motorways.
• Weekend and night ban for HGVs: no lorry driving Saturday 22:00 to Sunday 24:00, plus federal holidays, plus every day 22:00 to 05:00. Empty local delivery is exempt.

Alpine transits from Basel to Chiasso take approximately 4 hours in ideal conditions; that is one continuous drive within the 4h 30min limit but leaves no margin for queues. Plan a proper break in Airolo or Bellinzona.

Practical tips

• Buy the vignette before joining a motorway: CHF 40, see Switzerland toll roads.
• Lights on at all times: check before driving away from the hotel.
• Respect the 50 in town and 30 in zones: cameras are everywhere and tolerance is minimal.
• Phone in a cradle: do not touch the screen while moving.
• Snow chains November to April: keep a set in the boot if you are heading into the Alps.
• Random breath tests are normal: do not assume the police need a reason.
• Carry your driving licence: forgetting it costs CHF 20 in fines.
• Cash CHF in small denominations: useful for on-the-spot fines and unmanned parking machines.

Emergency numbers

• 112: general European emergency number
• 117: police
• 118: fire
• 144: ambulance
• 140: TCS roadside assistance (members and pay-as-you-go)
• 1414: REGA helicopter rescue (alpine emergencies)
