Duties of Marshals’
Marshals are required on the day of the trial to ensure the smooth running of the event. The number needed depends on many things, i.e. the type of trial, the venue, the size of entry, etc.  A marshal's duties are to officiate at each section (or as directed by the Clerk of the Course) and to ensure that each section is clear of vehicles and spectators before a competitor is allowed to attempt the section. A start marshal must also check the competitor and any passenger are wearing a seat belt (minimum lap strap) and not smoking, and that competing drivers do not passenger other drivers in the sections, and where a vehicle is driven by more than one person to make sure they spread out within the group.
