The Concise Oxford Dictionary gives the following definition of 'interrupt':
1 act so as to break the continuous progress of (an action, speech, a person speaking, etc.) ...3 break the continuity of.
An interruption can only occur if a journey has already commenced and can best be seen as a distinct break in that particular journey.
Delegates should collect the following information before establishing whether or not an interruption to the member's journey has occurred:
- a map of the journey taken, including where it was intended to finish
- how long the interruption was for
- how long the complete journey would usually take
- the reason for the interruption, particularly if factors outside the control of the client contributed to the interruption.
On the basis of this information, a judgement should be made whether an interruption has occurred or whether the deviation is better characterised as part of the overall journey.
Note that a journey should not be considered to be 'interrupted' if the client is unable to continue the intended journey because of travel factors outside his or her control (e.g. a blocked road, mechanical breakdown, etc.) and changes to a different mode of travel.
