Which of these actions is not necessary when approaching a pedestrian crossing?

When approaching a pedestrian crossing, actions like checking for pedestrians, slowing down, and yielding the right of way are essential for ensuring safety. By checking for pedestrians, you confirm that the crossing is clear or that there are individuals intending to cross, allowing you to react appropriately. Slowing down as you approach gives you the necessary time to observe the situation, enhancing your ability to respond if pedestrians are present. Yielding the right of way to pedestrians is not only a legal obligation but also a critical safety measure to prevent accidents.

The action of speeding up to cross quickly, however, is contrary to safe driving practices. It ignores the potential presence of pedestrians and increases the risk of accidents, compromising the safety of everyone involved. Thus, this action is deemed unnecessary and unsafe when approaching a pedestrian crossing.
