In which of the following situations can the ABS of a bus be ineffective when braking?

Explanation

Correct answer: When driving on uneven road surfaces.

The ABS system works by preventing the wheels from locking during braking. On an uneven surface, the wheels may temporarily lose contact with the road, which the system's sensors can misinterpret as a skid. As a result, the ABS, in its effort to restore traction, will unnecessarily reduce the braking force, which in effect can increase the vehicle's stopping distance.
