In which cases is it imperative to test the brakes?

The correct combination of testing the brakes is indeed important for ensuring safety on the road. According to German traffic regulations, it is imperative to check the brakes when driving a different vehicle because each vehicle may have different brake systems and characteristics. Testing the brakes when a vehicle has not been used for a longer period is crucial as rust or other issues can develop that might affect braking efficiency.

While each oil change is essential for vehicle maintenance, testing the brakes is not a standard requirement during that service. The focus should be on ensuring that your vehicle is safe to drive, especially after changes in use patterns or when switching vehicles. This is in line with ensuring road safety and preventing accidents. Understanding these rules helps maintain a safe driving environment for yourself and others.
