What is the primary pedagogical purpose of the Swiss mandatory 8-hour Road Safety Awareness Course (Verkehrskundekurs / VKU)?

1. To replace the basic theory examination with an instructor-led final test
2. To teach students how to repair combustion engines and rebuild carburetors
3. To conduct a mock practical examination on public roads
4. To develop traffic sense (Verkehrssinn), train sensory perception, teach hazard anticipation and defensive driving strategies, and understand physical and human risk factors before taking the practical test
