Driving in Adverse Conditions

Driving in adverse conditions means being

Switzerland’s weather can change quickly, especially in alpine regions. Adjusting speed, visibility, and reaction time is essential for safety.

In foggy weather, drivers must

Fog significantly reduces visibility. Turn on fog lights and drive slowly, leaving more space from the vehicle ahead.

When snow is falling, you should

Snowy roads can be slippery. Leave extra space to brake gently and avoid losing control.

During heavy rain, hydroplaning occurs when

Water buildup can cause skidding. Slow down and avoid sudden turns or braking on wet surfaces.

Winter tyres in Switzerland are

While not mandatory, winter tyres are essential in snowy regions. They greatly improve grip and reduce accident risk.

Black ice forms when

Especially common in Swiss mountain valleys. Drive slowly and avoid sharp maneuvers if ice is suspected.

On steep alpine roads in snow, you must

Engine braking helps control speed. Harsh braking on snow can cause skidding or loss of control.

Headlights during adverse conditions should be

In fog, snow, or heavy rain, visibility is reduced. Lights help you see and be seen by others.

In strong wind, your vehicle may

Keep a firm grip on the steering wheel. Reduce speed and watch for sudden gusts, especially on bridges or open highways.

In rain or snow, braking distance

Wet or icy roads reduce tyre grip. Always brake early and gently, never suddenly.

When driving through deep snow, you should

Stopping may cause your car to get stuck. Use lower gears and avoid abrupt steering.

Tunnel entrances in winter may have

Cold air near tunnels can freeze moisture. Slow down when entering or exiting tunnels in freezing weather.

When it rains after a dry spell

Oil and dirt mix with water, making roads dangerous. Reduce speed and be alert in these conditions.

If your car starts to skid, you should

Avoid braking hard. Ease off the accelerator and regain control by steering into the slide.

On narrow mountain roads during storms, be aware of

Adverse conditions can trigger landslides or rockfalls. Drive cautiously and observe warning signs.

In hail conditions, the safest response is to

Hail can damage your car and impair vision. Pull over in a sheltered area until it passes.

Windshield wipers must be

Effective wipers improve visibility in rain and snow. Replace them regularly, especially before winter.

Adverse conditions increase fatigue, so

Driving in stress-inducing weather is tiring. Rest regularly to stay focused and alert.

ABS and ESP systems are helpful because

Most Swiss cars have these safety features. They help maintain control, but cannot replace cautious driving.

When vision is reduced, always

Lane markings are guides in poor visibility. Keep safe spacing and follow road edges where needed.

Driving in thick snow without snow chains may

In some regions, snow chains are required. Signs will indicate chain zones—follow them for safety and legal compliance.

During snowfall, always clear

Driving with snow-covered windows is illegal and dangerous. Ensure full visibility before moving.

In dense fog, if visibility is under 50m

Swiss road law requires speed reduction based on visibility. Use fog lights and increase caution.

Road salt in winter may cause

Freshly salted roads can be unpredictable. Drive slowly and wash your vehicle often to avoid salt corrosion.

Steep downhill roads in snow require

Brakes can overheat on long descents. Use gears to control speed gradually and safely.
