Clearway

The traffic lanes of the sea can be clearways for thousands of miles.

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. the “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.

A clearway may be provided to extend the takeoff distance available (TODA) beyond the end of the hard surface which defines the declarable length of the available takeoff run (TORA).
