CARO provides a variety of handbooks to support participants, hosts, and judges involved in Rally and Working trials.
This page offers links to the Rally and Working handbooks, along with any updates or clarifications since the last published versions. It also includes downloadable PDFs of all Rally signs. For virtual trials, the Virtual Trial Companion Handbook outlines course setup and recording instructions for both Rally and Working.
The Trial Official’s Handbook, designed for judges and trial hosts, is available under the Host/Judges menu.
Additionally, CARO offers a mobile app with detailed information about each Rally sign and Working exercise. The app can be downloaded from Google Play or the Apple App Store.
