- 1/30At driving in built-up areas
In Swiss cities and built-up areas, trucks and buses must not exceed 50 km/h.
If approaching traffic lights in urban zones
Urban limits require 50 km/h max, slowing further if traffic density is high.
To ensure pedestrian safety in city centres
City driving requires keeping to the 50 km/h limit for safety.
At night in residential streets
Night-time driving in built-up areas must remain at 50 km/h or lower.
If turning in urban intersections
In tight urban turns, commercial vehicles should slow to below 50 km/h.
At operating trucks on motorways
Trucks and buses on Swiss motorways may not exceed 80 km/h.
To comply with expressway rules
On expressways, trucks and buses are limited to 80 km/h.
If overtaking on a motorway
Overtaking manoeuvres for commercial vehicles must stay within 80 km/h.
At joining expressway traffic
Entry lanes must be used to reach, but not exceed, 80 km/h.
To maintain control on downhill motorway slopes
Steep motorway descents require speeds within the 80 km/h limit.
If entering a school zone
School zones require trucks and buses to slow to 30 km/h.
At driving through industrial estates
Industrial areas often have limits between 30 to 50 km/h.
To protect workers in loading zones
Active loading zones require slowing to 30 km/h or less.
If crossing pedestrian-heavy industrial areas
Heavy vehicle traffic must keep to 30 to 50 km/h limits in these areas.
At approaching school crossings
School crossings require trucks and buses to limit speed to 30 km/h.
To drive safely in rain
Wet roads require lowering speed below 50 km/h in cities and 80 km/h on highways.
At driving in fog with under 50 m visibility
Poor visibility requires trucks and buses to stay at 50 km/h or lower.
If snow or ice present
Hazardous surfaces may require slowing well below 50 km/h in urban and 80 km/h on highways.
To control a heavy load on bends
Stability issues may require going under 50/80 km/h legal limits.
At carrying an unstable or top-heavy load
Load shift risks require reducing speed below 50 km/h in cities and 80 km/h on highways.
If crosswinds affect control
On open motorways, lower speed from the 80 km/h limit for safety.
To meet braking distance needs in wet weather
Longer stopping distances require reducing from 50/80 km/h posted limits.
At descending with full load
Downhill braking with full loads should stay under 80 km/h motorway limit.
If approaching sharp curves on rural roads
Curves require slowing below the rural or motorway 80 km/h limit.
At overtaking cyclists in urban areas
Passing cyclists in built-up areas must be within 50 km/h limit.
To avoid spray in wet weather
Wet roads require trucks to drop below the 80 km/h highway limit.
If near temporary work sites
Work zones often require speeds between 30 to 50 km/h.
To adjust for reduced tyre grip
Poor tyre grip demands reducing from 50/80 km/h posted limits.
At entering narrow village streets
Tight rural settlements require speeds between 30 to 50 km/h.
If unsure of the local limit
Default limits are 50 km/h in built-up areas and 80 km/h outside unless posted.
