Moderate speed where visibility is restricted

Where the view ahead is restricted, drivers must moderate speed so that they do not create danger and can react safely to an obstacle or other unexpected event. In practice, they must be able to stop within the distance that can be seen to be clear. The choice must also reflect the driver's physical and mental condition and the load, which can affect stability and stopping distance. It does not depend on the time available to reach the destination or merely on being outside a built-up area; actual conditions are what matter.
