Learn: reading an FIA road book

1. The road book: What an FIA road book is: one road book per Stage, colour on white, English only, paper (A5) or digital; a line is three boxes (distance, diagram, description); the road book prevails over the NAV-GPS except for speed limits.
2. Distances: Total and partial distances (decimal comma, two decimals), the arrow and green box when the next box is less than 300 m away, MODIF and NEW NOTE, and the tripmaster.
3. The diagram (tulip): Reading the tulip: the route to follow is blue including the arrow, off track is a dashed blue line, other tracks are black, sandy areas yellow, important information red.
4. Headings (CAP): Headings are given only where necessary, as a number without degree sign, highlighted; A = average heading of the next diagram box, C = calculated.
5. Dangers: Three danger levels, ! !! !!!, always red and the same size; !!! is always a WPS with a red frame around the line. The FIA attaches no speed limit to danger levels.
6. Waypoints: Waypoint types (WPM, WPE, WPN, WPS, WPC, WPP, WPV) with their opening and validation radii, how they are marked in the road book, penalties, and how many you may miss per Stage.
7. Speed zones and controls: Speed control zones from DZ to FZ (30, 50 or 90 km/h) and when penalties apply, passage controls (CP), neutralisation and transfer zones, and the control signs on the ground.
8. The full lexicon: All 163 symbols of the FIA road book lexicon, searchable.
9. Abbreviations: The official English road book abbreviations (kpL, HP, TJS, Qᵀ, -V, ET…), their meaning, and the waypoint and control codes used in the regulations.
10. The official examples: The two FIA example road book pages (Examples I and II), read line by line.
11. Motorbikes (FIM) and cars (FIA): What differs between the FIM motorbike rules and the FIA car rules, limited to what could be verified.
12. Navigator’s advice: Navigation practice, marked as advice and not rules: keep the trip honest, read ahead, what to do when lost, and personal notes.
