THE WELSH XTREM 2020
- The object of the event is for a single vehicle to locate various marker Points, the location of which will be indicated on the day. Each punch will be identified by a number to verify it is the desired objective. The punch will be attached to a fixed point on the objective either by cable or direct fixing. The control card (attached by the scrutineer to a consistent point on all vehicles) must be marked with the pin punch in the correct box on the control card as proof that the objective has been visited. The vehicle must negotiate close enough to the point to collect the punch mark without detaching either pin punch or control card.
- There may be random Alcohol Breath tests done during the course of competition time and anyone who is believed to be over a unsafe Drink Drive Limit will be held back until safe to drive or help. The use of any prohibited/banned substances is strictly not allowed at any time and will lead to immediate disqualification from the event with a possible future ban from competing at this event and others of a similar nature.
- There may also be special tasks which are worth extra points. These are generally along the lines of non-driving puzzles or may include driving a short course through numbered gates in reverse gear or against the clock.

We will also uphold this rule for other organisers events for the benefit of safety and reputation of our sport.
- If you feel at any time that the severity of a section is beyond your capability you must stop. You will not be forced into a situation you consider to be potentially dangerous. All sections, punches and other parts of the event are voluntary. You should not attempt them if you feel it is outside you or your vehicles capability.
- Pets are permitted in the main event control and the camping area only. They are NOT permitted onto the site(s) or areas where the competitors are actually competing. For example; if the campsite is in a field and they are competing in a wood, then pets are NOT permitted into ANY PART of that wood. You are responsible for the safe handling and safety of your pets. The organisers and/or sponsors and/or competitors take no responsibility for the actions of your pets or any damage (immediate or otherwise) that they may cause.
