What is the effect of an automatic anti-locking device (ABS)?

The combination you selected is correct because both options highlight the key benefits of an anti-lock braking system (ABS). Option 1 emphasizes that ABS helps achieve optimal braking on wet roads, which is crucial for maintaining safety as it prevents skidding. Option 2 explains that ABS allows the driver to maintain steering control during braking, which is vital for maneuvering away from obstacles.

However, option 3, which states that aquaplaning is prevented, is not accurate as ABS does not prevent aquaplaning; it only helps manage braking in slippery conditions. Understanding these distinctions is important, especially in accordance with German traffic law, which prioritizes safety and effective vehicle operation under various conditions. Knowing how ABS works can significantly enhance a driver's ability to respond to emergencies on wet roads.
