In the past several years, the Federal Roads Office (ASTRA) has identified nearly 950 high-accident zones on Switzerland’s road network. What is being done to improve safety there?
In 2025, 4,149 people were killed or seriously injured in 2025 while driving in Switzerland, according to ASTRA.
While an accident can happen anywhere, some roads record more incidents than others, and are therefore deemed more dangrous for motorists.
This interactive map shows where in Switzerland most accidents occur, and what type.
ASTRA has identified these three sections as among most dangerous on the national road network, with a particularly high number of accidents occurring there:
- Wangen-Brüttisellen (Zurich)
- Gubrist Gateway (Zurich
- Egerkingen Junction (Solothurn)
Additional lanes for better traffic management
The Wangen exit off the A1 motorway in particular is deemed one the riskiest spots, with numerous rear-end collisions occurring there.
Therefore, from 2028 onwards, emergency stopping shoulders will be transformed into traffic lanes.
This means that an additional lane will be created to absorb traffic and help it flow more easily.

Which Swiss cantons have the most traffic accidents?
According to the Federal Statistical Office (FSO), Zurich tops the charts in this regard, with 3,553 accidents.
Next are:
- Bern (2.547)
- Vaud (1.660)
- Geneva (1.230)

- Lucerne (1.017)
- St. Gallen (980)
- Ticino (676)

On the positive side, however, Switzerland’s roads are considered “exceptionally safe” and well-maintained, with the lowest fatality rates in European comparison, according to the road safety report by the European Commission.
