What speed should drivers maintain when approaching a pedestrian or bicycle crossing?

The correct answer is that drivers should maintain a speed that allows them to stop at any time when approaching a pedestrian or bicycle crossing. This is crucial for ensuring the safety of pedestrians and cyclists who may be using the crossing. By driving at a speed that provides ample reaction time, drivers are better prepared to respond to unexpected situations, such as a pedestrian stepping onto the crossing or a cyclist merging into the lane.

In situations where a driver feels unsure about the crossing or the movements of pedestrians and cyclists, it's important to exercise caution and adjust speed accordingly. This proactive approach not only helps in preventing accidents but also demonstrates a responsible attitude towards road safety.

Maintaining a safe speed helps to create a predictable environment for all road users, promoting better awareness and reducing the risk of collisions. Therefore, the emphasis is on the requirement to be able to stop readily, rather than adhering to arbitrary speed limits that do not take the dynamic situation of crossings into account.
