Yellow marker boards are used for a mumber of things:
1. There is a yellow warning board about 100m before the red finish board.
2. There is a yellow warning board about 100m before the blue radio/medical board (this can be in the middle of a stage). This is to indicate the location of radio or medical people.
3. A start control will have a yellow board to mark the start of the control zone.
Basically, the yellow board is a warning board for some other type of board.
