While driving, you use your vehicle’s adaptive cruise control (ACC) system. What must you anticipate in these weather conditions?

In snowy or adverse weather conditions, the functionality of adaptive cruise control (ACC) may be compromised. This is because sensors can be affected by snow or ice, making it difficult for the system to accurately measure speed and distance. Therefore, it is essential for drivers to take personal control over their speed and distance from other vehicles.

In such situations, trusting the ACC alone can be risky, as it might not respond correctly to changes in road conditions or vehicle behavior. This is why both points in your answer are crucial: the inability of ACC to function properly and the need for personal control to ensure safety while driving. The inclusion of these considerations aligns with German traffic regulations that emphasize driver responsibility, especially in poor weather conditions.
