The red cross means no stopping, not even to pick up or set down passengers. The sign is used to indicate a 24-hour clearway (usually on a rural road) or may be incorporated into other signs with the words? No stopping? (e.g.? no stopping except local buses? Sign at bus stops). On a 24-hour clearway, the prohibition of stopping applies only to the main carriageway. You may stop in a lay-by unless there are signs to say otherwise. A 24-hour clearway does not have any special road markings, but there should be smaller repeater signs at approximately one-mile intervals.
In areas of street lighting (except on motorways), a speed limit of 30mph applies unless another speed limit is specifically signed.
