Roadbook

A roadbook is a detailed navigational guide used in rally racing and off-road motorsport events that provides drivers and co-drivers with precise route instructions.

Typically presented in a scroll format that advances as competitors progress, roadbooks contain critical information including distances, directional changes, hazards, and landmarks. They often use standardized symbols and "tulip diagrams" (simple arrow-based illustrations) to indicate turns and route features.

In events like the Dakar Rally, the roadbook serves as the primary navigation tool, requiring co-drivers to interpret these instructions while moving at high speeds across challenging terrain. Modern competitions may use digital roadbooks, though many traditional rallies still rely on paper versions.
