Driving and judging dressage is a symbiotic process. Drivers are trying to interpret the requirements of the tests, while judges are trying to estimate the success of the driver's efforts. Both parties need to have roughly similar ideas about the whole purpose of the exercise. The object of this book is to discuss the meaning of the FEI rules for dressage and the problems facing both drivers and judges in meeting the intentions and purposes of the dressage discipline. The author makes the point that, while driven dressage is derived from the ridden discipline, it poses very different problems for both drivers and judges. Pulling even a lightweight carriage in a dressage test requires the horse to use quite different muscles and the driver to use different aids in order to achieve a well-balanced, accurate and lively performance. It is these differences that judges need to understand and appreciate in order to mark all competitors fairly. The book is written in the hope that it will help beginners on both driving and judging dressage.
