Speed Limits and Control

When driving within urban areas such as towns and cities

The general urban limit for built-up areas unless otherwise posted. Look for signs indicating zones with stricter limits such as residential or school zones.

On roads passing through residential or school zones

These are Tempo 30 zones meant to protect children and pedestrians. Speed bumps, narrowed roads, and signs reinforce compliance.

On rural roads outside built-up areas

Applies to all vehicles unless indicated otherwise. Be especially cautious of agricultural vehicles, wildlife, and cyclists.

On expressways and semi-motorways in Switzerland

Applies to roads with controlled access but fewer features than full motorways. Check for variations at entrances or curves.

On Swiss motorways autobahns

This is the top legal speed in Switzerland. Always adjust based on weather, traffic, or vehicle load.

In areas with road construction or maintenance

Speed is often reduced to 60 or 80 km/h depending on roadwork. Fines are doubled for violations in these zones.

During adverse weather conditions such as snow or fog

Drivers are legally obligated to reduce speed based on conditions. Using fog lights and keeping a safe following distance is essential.

On roads with electronic speed signs or variable message boards

Speed limits change dynamically due to congestion, accidents, or weather. These limits are legally enforceable.

When towing a trailer on Swiss roads

This is the maximum allowed on motorways for vehicles with trailers. On other roads, it can be even lower.

For new drivers probationary license holders

While limits remain the same, new drivers must drive with extra care. Violations may affect the probationary period.

In areas marked as Zone 20 or Meeting Zones

These are shared zones where vehicles must yield to pedestrians at all times. Designed to encourage calm and safe driving behavior.

When approaching a sharp curve or mountain pass descent

Use engine braking and keep a lower gear. Sharp curves on alpine roads are often unsignposted—anticipate them.

On steep downhill slopes marked with “Dangerous Descent” signs

Continuous braking can cause brake failure. Shift to lower gear to use engine braking for better control.

When approaching tunnels on Swiss highways

Tunnel speed limits are strictly monitored. Keep safe spacing and use headlights. Avoid stopping or overtaking inside the tunnel.

In fog with visibility less than 50 meters

Use dipped headlights or fog lights. Avoid overtaking and increase the following distance.

When descending a snowy or icy slope in winter

Avoid sharp steering or hard braking. Use winter tires or snow chains if required.

On roads with fixed speed cameras or radar control

Switzerland enforces strict speed laws. Even 1–5 km/h over the limit can result in a fine or license suspension.

When entering a tunnel where speed and spacing cameras are active

Maintain both consistent speed and a minimum gap e.g. 50 meters. Alerts are usually displayed before entering.

On narrow alpine roads with limited visibility and sharp bends

Use horn at blind curves, be prepared to yield, and drive as far right as safely possible.

In urban zones where bicycles and pedestrians mix with cars

Expect unpredictable movements, especially from children and older pedestrians. Cyclists may share lanes with vehicles.

When road signs display a speed limit enclosed in a red circle

This is a regulatory sign, not an advisory one. Exceeding it is a traffic offense subject to fines and points.

When leaving a higher speed zone and entering a marked 50 km/h zone

Begin slowing down before reaching the posted speed limit sign, not after. Enforcement may begin immediately at the sign.

If no speed limit is posted in a parking area or private road

Drive at walking speed approx. 5–10 km/h and yield to all pedestrians and cyclists.

When approaching speed bumps or raised pedestrian crossings

Typically located in residential zones or near schools. Failure to slow down may damage your suspension and endanger people.

On roads near schools, hospitals, or playgrounds

Even without specific signage, reduced speed is expected due to high pedestrian activity and potential for sudden crossings.
