Compass headings, tulip boxes, exclamation marks, cascading distances: the first time you open a rally raid roadbook, it looks like hieroglyphics. Yet learning to read a rally raid roadbook comes quickly, because every box follows the same logic and three pieces of information are enough to hold the track: the distance, the drawing, the heading. Here is the competitor's guide, from the first box to resetting the tripmaster, and what the electronic roadbook changes about the reading.
The grammar of a rally raid roadbook: one box, three columns
A rally raid roadbook is not a map: it is a sequence of boxes (or frames), each describing one precise point of the route, in the order the crew will meet them. Whatever the event, a box is organized in three columns:
- On the left, the distances. The total distance, accumulated since the start of the stage or special, and the partial distance, which separates this box from the previous one.
- In the middle, the drawing. This is the tulip, inherited from the Tulip Rally of the 1950s, which popularized this kind of diagram: a dot marks where you enter the junction or situation, an arrow shows the exit to take.
- On the right, the observations. Danger symbols, abbreviations, terrain notes and, often, the compass heading to follow in degrees.
You read box by box, never ahead: the co-driver (or the rider on a bike) only holds the current box and the next one. The rest of the roadbook waits its turn. That rhythm, distance called, situation recognized, exit confirmed, is what clean navigation sounds like.
Symbols: the legend before the dust
Every organizer attaches a legend page to its roadbook: the key to the symbols and abbreviations used on the event. It is the first thing to read, before the first box, because conventions vary from one event to the next. A few families of symbols show up everywhere:
- Dangers, graded from one to three exclamation marks: one calls for attention, two means slow down firmly, three announces a major hazard (a hole, a step, an off-camber section) to cross at very low speed.
- Terrain: surface changes, sand, rocks, a ford, a steep climb or descent.
- One-off obstacles: a gate, a fence, a narrow passage, a crossing with a road open to traffic.
- Control points: waypoints to validate, starts and ends of speed-limited zones, passage controls.
In the evening at the bivouac, when the rules allow it, crews highlight their roll: one color for dangers, one for headings, one for direction changes. That marking prepares the next day's reading: in the special, the eye has to catch the information in a fraction of a second.
Headings and distances: riding to the tripmaster
The heading (CAP followed by a number on French-speaking events) is a compass direction in degrees: 0 or 360 for north, 90 for east, 180 for south, 270 for west. CAP 120 therefore means: leaving this box, hold a general east-south-east direction until the next instruction. On off-track sections, where no path materializes the line, the heading becomes the primary information: you hold it on the compass or heading repeater, absorbing the detours the terrain imposes.
The distances are read on the tripmaster, the onboard odometer: it displays the total distance and the partial, reset to zero at each box. The routine never changes: the partial approaches the value of the next box, the crew looks for the situation drawn in the tulip, recognizes it, takes the indicated exit, zeroes the partial. The distance sets the rhythm, the drawing confirms the place, the heading validates the exit. When all three agree, you are on the right track; when one of the three does not fit, you slow down and check before committing.
Resetting: correcting the drift before it gets expensive
A tripmaster drifts, inevitably: wheels spin in the sand, the crew goes around an obstacle, tire pressure changes the rolling circumference. Kilometer after kilometer, the gap grows between the displayed distance and the roadbook's, and instructions end up landing next to reality.
The remedy is the reset: at every safe, unmistakable landmark (a marked junction, a village, a bridge, a beacon), you correct the tripmaster's total distance so it matches the box exactly. Good co-drivers reset often, in small touches, rather than letting the gap accumulate. And when real doubt sets in (nothing has matched for several boxes), the rule is to return to the last confirmed point rather than keep improvising: a few minutes lost beat a full off-course excursion.
What the electronic roadbook changes about the reading
On the major events, the tablet has replaced the paper roll: the Dakar switched to a fully digital roadbook in 2023, with scrolling driven from the handlebar or the screen. The structure of the boxes does not change: same distances, same tulips, same headings. What changes is the preparation. The digital roadbook is only handed out minutes before the start of the special, precisely to prevent the night-before work: no more homemade highlighting, the markups (dangers, headings, direction changes) are baked in by the organizer, identical for everyone. Cold reading, with no prior pass over the document, becomes a skill in its own right again.
On the organizer's side, the digital roadbook opens other possibilities (instant distribution, last-minute corrections, identical versions for every crew): we cover that side in our article on the digital roadbook and GPS tracking. On the competitor's side, the navigation app complements the official roadbook without replacing it: the day's route and offline maps preloaded, as the navigation features RaidLine provides to equipped events in white label allow. And while the crew reads its boxes, its tracker reports its position to race control and the public map: that is the subject of our guide to rally raid live tracking.

Roadbook reading is a motor skill, and motor skills are built by repetition. Before your first event:
- Ride to a roadbook in training, even on road liaisons: holding a partial, calling a box, zeroing the odometer, the rhythm is acquired before the race, not during it.
- Learn your event's legend by heart. In the special, it is too late to look up what a symbol means.
- Split the roles in the crew: who calls, who resets, who decides when in doubt. Two people hesitating costs more than one person being wrong.
- Prepare the hardware that carries the reading: roadbook holder, tripmaster, heading repeater, power supply. Our competitor navigation gear checklist goes through every item.
- Plan for dead zones: maps and routes must be loaded before the start, as our article on offline GPS navigation in rally raid explains.
And if you are starting from zero, begin with the big picture: our guide to entering your first rally raid covers entry, budget and preparation, of which navigation is only one chapter.
Frequently asked questions
What is the difference between total and partial distance?
The total distance is the mileage accumulated since the start of the stage or special; the partial distance is what separates a box from the previous one. You ride to the partial, which sets the rhythm of the instructions, and you check the total to reset the tripmaster at landmarks.
What do the exclamation marks in a roadbook mean?
They flag a danger, graded from one to three exclamation marks: one calls for attention, two means slow down firmly, three announces a major hazard to cross at very low speed. The exact definition of each level is in the event roadbook's legend.
How do you reset your tripmaster during the race?
At every unmistakable landmark (a marked junction, a village, a bridge), you correct the total distance shown by the tripmaster so it matches the roadbook box. Resetting often keeps the drift from accumulating and the next instructions from landing in the wrong place.
Does the electronic roadbook replace paper?
On the major events, yes: the Dakar switched to a fully digital roadbook in 2023, handed out minutes before the start of the special. Many amateur raids still run paper rolls. The reading itself does not change: same boxes, same tulips, same headings; what disappears is the night-before preparation.
