No real problem I think: being responsible for isn't the same as carrying it at all time, no?

14.3 TIME CARDS
14.3.1 Each crew is responsible for:
- Its time card.
- Submitting the time card at the controls and for the accuracy of the entries.
- Any entries made on the time card.
14.3.2 The appropriate marshal is the only person allowed to make entries on the time card, except for
the sections marked “for competitor’s use”.
14.3.3 In case of the absence of a stamp or signature from any control, the absence of a time entry at a
time control, or the failure to hand in the time card at each control, the crew concerned will be considered to
have retired at that control. This information will be pronounced by the clerk of the course at the end of a
section.
14.3.4 Any divergence between the times entered on the crew's time card and those entered on the official
documents of the rally will form the subject of an inquiry by the clerk of the course.
