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

The automatic anti-locking device, or ABS, is designed to enhance vehicle safety during braking. It works by preventing the wheels from locking up, which helps maintain steering control even when braking hard. This is particularly important on wet or slippery road surfaces, as it allows the driver to maneuver the vehicle while applying maximum brake pressure.

The correct options highlight two key effects of ABS: first, that it provides optimal braking on wet roads to prevent skidding, and second, that it allows for better steering control during braking. While ABS helps with stability and control, it does not directly prevent aquaplaning, which is a separate phenomenon that occurs when tires ride on water instead of the road surface.

It's essential to recognize that the effectiveness of ABS is contingent upon its proper operation; therefore, the selected combination of answers accurately reflects its role in vehicle safety during adverse driving conditions. Understanding this helps drivers make informed decisions about their driving behaviors and vehicle maintenance in accordance with German traffic regulations.
