Crews are limited to 2 runs through the stages. This is the time that the driver and co-driver will make the pace notes to call out to the driver during the rally.
Remote Service: The stages on Friday are too far away from the Service Park in Cardiff to allow the drivers to return in the middle of the day, so a remote service is used closer to the stages. Remote Service on Friday takes place at Builth Wells Showground.

Time Penalty: If crews are late at a Time Control they are given a time penalty. For early arrival - 1 minute per minute or fraction of a minute early. For late arrival - 10 seconds per minute or fraction of a minute late.
Tulip Diagrams: Schematic diagrams used in the Road Book to indicate which direction the crew should take at junctions. Introduced by the Tulip Rally in the 1950s.
