In the Dakar Rally, the co-driver or navigator is the vehicle's moving guidance system. While the driver controls speed, steering, and traction, the navigator reads the roadbook, checks instruments, watches time, and calls out instructions before hazards arrive. This role matters because teams travel across deserts, rocks, dunes, and tracks where normal maps or road signs are often not enough.
A good navigator helps the team stay fast, safe, and on the correct route.
Key Facts
- Average speed = distance ÷ time
- Time = distance ÷ speed
- If a vehicle travels 18 km in 12 min, its average speed is 90 km/h.
- Roadbook notes connect distance, direction, hazards, and landmarks into a step by step route plan.
- A trip meter measures distance traveled so the navigator can match the vehicle position to each roadbook instruction.
- Clear communication reduces reaction time because the driver can prepare for turns, dunes, rocks, and speed changes before reaching them.
Vocabulary
- Roadbook
- A roadbook is a set of route instructions that lists distances, compass headings, landmarks, hazards, and navigation symbols for a rally stage.
- Co-driver
- A co-driver is the team member who navigates, manages timing, reads the roadbook, and communicates instructions to the driver.
- Trip meter
- A trip meter is an instrument that measures the distance traveled so the navigator can match the vehicle's position to the roadbook.
- Waypoint
- A waypoint is a required location on the route that teams must pass to confirm they are following the correct course.
- Heading
- A heading is the direction of travel measured in degrees, usually from north on a compass or navigation display.
Common Mistakes to Avoid
- Confusing speed with progress along the route is wrong because a fast vehicle can still lose time if it misses a waypoint or takes the wrong track.
- Reading only the next roadbook line is wrong because the navigator must look ahead to prepare the driver for hazards, turns, and terrain changes.
- Ignoring trip meter calibration is wrong because a small distance error can grow into a large position error over many kilometers.
- Giving long or unclear calls is wrong because the driver has only a short time to react while controlling the vehicle over rough terrain.
Practice Questions
- 1 A rally vehicle travels 42 km across desert terrain in 28 min. What is its average speed in km/h?
- 2 A roadbook note says the next waypoint is 15 km away. If the team averages 75 km/h, how many minutes will it take to reach the waypoint?
- 3 A navigator notices that the trip meter distance is 0.6 km greater than the roadbook distance after a long rocky section. Explain how this could affect navigation and what the navigator should do before the next major turn.
