Cross Country Vehicle (CCV) trialing is the next step up from RTV trialing and is open to non-road-legal vehicles, which greatly increases the scope for modification. The terrain covered will be of greater difficulty than that found on an RTV trial, and will usually require more judicious use of speed to get the vehicle across certain obstacles, so increasing the risk of vehicle damage. Whilst no trial is intended to be vehicle-damaging mistakes and accidents are inevitable. A standard-specification vehicle would not be expected to be able to complete a CCV course.
