A "road book" is a detailed guide used primarily in motorsport events, such as rally racing. It provides essential information about the route, including distances, directions, and specific instructions for drivers. The road book helps participants navigate the course safely and efficiently, ensuring they follow the correct path during the competition. Typically, a road book includes maps, notes on road conditions, and points of interest along the way. It is crucial for teams, including drivers and co-drivers, to study the road book thoroughly before the event to prepare for any challenges they may encounter during the race.
