Timing and Scoring
Timing was to the forward minute except on Special Sections with crews able to nominate their time if early. Scoring was 1 point per minute early or late, except on Special Sections where it was stated as 1 point per unit, and based on the previous year, it is assumed that a unit was a sixth of a minute so that crews lost 6 points per minute, but it may have been quarter minute timing and 4 points per minute. There were a limited number of these Special Sections.
Wrong directions or missing a passage control cost 25 points, except on Special Sections where the penalty was 100 points. Missing a main control (or exceeding late time) cost 150 points.
Exceeding late time by more than 30 minutes at a division end resulted in exclusion. There was no requirement to complete any particular proportion of the course in order to be classified as a finisher.
Other
Starting order was by ballot.
Cars were permitted to be worked on at any time, including in control, except for the impound at restbreaks.
