This category includes a variety of events, including Trials, Competitive Safaris and Team Recovery Competitions, all of which take place over difficult terrain and call for specialist vehicles, normally with four-wheel drive.
While each event has its own rules, they are all based on the ability of the specialist vehicle to encounter and overcome various obstacles.
Cross Country Trials are for four-wheel drive and other vehicles designed to cope with really rough terrain. However, some trials also include classes for road-taxed vehicles, with sections laid out so as not to cause undue damage.
Some types of event, such as Competitive Safaris and Hillrallies, are run against the clock, calling for driving skills and vehicle preparation similar to those found in Special Stage Rallies.
