Trials Rules

GENERAL SAFETY & EVENT RULES

  1. GENERAL RULES
    1. This list should be read in conjunction with the technical rules. In the event of a conflict, the technical rules will prevail.
    2. Events run by Challenge South West are normally for individual vehicles (unless otherwise stated), each of which may carry one driver and one crewperson providing they are accommodated in securely fixed seats and wearing approved seatbelts or harnesses. All drivers must have current UK driving licences.
    3. The driver and crewman entered for an event may swap/share the driving and navigating roles providing both have full driving licences.
    4. All vehicles entered must comply with the technical rules of the Club as regards construction and equipment.
    5. Horns will be used to notify of an emergency. On hearing horns competitors should attempt to assist/locate the problem and notify a marshal.
    6. Vehicles do not have to be Taxed & MOT’d etc but may still enter and compete if they are fully road legal.
    7. Vehicles must carry a first aid kit and fire extinguisher (of the type specified in Technical Regulations no 3)
    8. All items must be securely stowed within a vehicle.
    9. A blanket speed limit of 15mph covers all sites and any vehicle exceeding this may be disqualified from the competition.
    10. Terra Tagging events are not set out as winch challenge events and winches are not required. Should they be used for vehicle recovery in the event that a recovery marshal vehicle is not available the following rules apply:
      • Any winch must pass scrutineering to be used even for self-recovery purposes
      • Wire Cable is no longer permitted for use at any CSW events.
      • Winch sails must be used with all winch lines when crossing a track and should be positioned on the line in the centre of the track.
    11. The use of gloves is compulsory when handling all winch/recovery equipment.
    12. There must be no damage or removal of any object within the competition area (i.e. trees, fences, gates, walls etc.).
    13. Tree strops (not choked!) must be used at all times to prevent damage when using a tree as an anchor point. Competitors must not attempt to use an anchor point already being used by another competitor.
    14. ‘Clear for winching’ must be called out clearly prior to every winching operation if there are spectators present. Competitors must ensure that winch cables are never crossed.
    15. In the event of a breakdown, repairs must be carried out on a suitable ground sheet or preferably a proper oil absorbent mat. Never spill fuel or oil or drop litter. In the event of any spillage prevent it from spreading and inform a marshal.
    16. All competitors will obey the organisers / marshals instructions. Their decision in all matters is final. Event organisers may also include any site specific rules as appropriate to the site or conditions.
    17. Intentional outside assistance (spotting or physical help) which may contribute to a team gaining points is not is permitted while competing. Any team found breaking this rule may be subject to disciplinary action or automatic disqualification.
    18. If you feel at any time that the severity of the terrain is beyond your capability you must stop. You will not be forced into a situation you consider to be potentially dangerous and assistance will be provided if required.
    19. The person entering the event as driver shall remain as the driver throughout the event. If the crew is found driving the vehicle while competing, that team will be disqualified from the event. s) No additional passengers (other than 1 crew member) allowed in or on a vehicle travelling between sections, stages or punches unless otherwise stated.
    20. Your punch card is very important. You must take care of it at all times, as if the card is detached from the attaching cord without authority then all punches scored to that point are lost. If the card is becoming unusable, you can approach a marshal to ask for a replacement and in this situation the old card will be removed for you and a new one fitted, all punches on the old card being retained.
  2. WARNINGS & PENALTIES
    1. In the event of an infringement of these rules, if possible there will be one verbal warning given before a penalty is charged. If a penalty is charged every effort will be made to advise the competitor at that time. Remember that the rules are there for the protection of yourself and others.
    2. The organisers or marshals may award penalties to, or disqualify, a competitor without first providing a warning if the act carried out was deemed by the organiser or marshal to be severe or dangerous enough to warrant such a penalty or disqualification. Any and all decisions of this nature shall be notified to the event organiser as soon as practicable. Disqualification decisions should be notified to the event organiser and confirmed immediately. For other penalties, competitors have the right to appeal to the event organiser in the case of extenuating circumstances or other excuse and his or her decision on such an appeal will be final. All decisions shall become final in any case on completion of the event.
    3. We strongly recommend new members seek advice before carrying out modifications but as a minimum we recommend getting their vehicle checked by a club scrutineer prior to an event.
    4. Breaches of safety standards will be noted and if not resolvable on the day may prevent you from competing. Continued breaches of safety standards after being notified WILL prevent you from competing and may result in disciplinary action and lead to membership cancellation with no refund.
    5. Competitors are not allowed to smoke while competing.
    6. We reserve the right to carry out random Alcohol testing in the mornings on two day events. This will be for both drivers and navigators. Any competitor failing a morning after test will not be allowed to compete until they can pass a retest. The organiser’s also reserve the right to do spot tests at any point during a competition. Should any competitor exercise their right to refuse a random alcohol test the organizer reserves the right to disallow that competitor from continuing with the competition and this may also lead to disqualification from the competition.

TECHNICAL RULES & REGULATIONS

All Competitors MUST carefully read these rules and regulations and make sure their vehicle complies with the requirements. In the event of any queries please contact a CSW official for advice. Breaches of safety standards will be noted and if not resolvable on the day may prevent you from competing.

It must be noted that these regulations are not exhaustive and although CSW are not affiliated to the MSA many of the regulations are the same and often refer back to the MSA Blue Book. A copy of this book may be viewed online at www.msauk.org. We recommend before making any alterations to any vehicle that you also check the Technical Regulations specific to Cross Country Events in the current MSA Blue Book. These regulations shall be deemed to be correct in the event of any conflict between these rules and the MSA Blue Book.

  1. SCRUTINEERING
    1. Driver and crewperson of all competing and recovery vehicles must present their vehicle (in a clean condition) to the scrutineer for inspection prior to the start of an event. After such time the scrutineer may inspect any late arrivals as/when time allows!
    2. Vehicles do not need to be taxed or MOT’d. Road legal vehicles will still be allowed but there will be no separate classes or prizes.
    3. All vehicles must be presented for scrutineering in a clean condition including tyres with a minimum tread to be road legal.
    4. All drivers must hold a current UK Driving Licence unless otherwise stated in the Supplementary Regulation of the event.
    5. Competitors will be immediately advised if their vehicle fails scrutineering, and be advised of all reasons for failure. Competitors will be given every opportunity to rectify any defects prior to commencing the event. Should a vehicle be prevented from competing due to failing scrutineering, no refund of any entry fees will be made.
    6. Should any vehicle be presented with what is considered by the event scrutineer to be a safety critical defect, or indeed be lacking any item of safety critical equipment, then it will not be allowed to complete in that event.
    7. Should any vehicle be presented at any three consecutive events with the same minor defect(s), then the vehicle shall not be allowed to compete in that event.
    8. All decisions to prevent any vehicle from competing shall be ratified as soon as practicable by a second member of the CSW committee, at which point the decision will become final.
    9. Any club member so wishing can request that their vehicle be assessed by a club scrutineer to give an indication of the vehicles compliance with club rules and regulations. Such requests will be granted at the discretion of the club.
  2. RECOVERY EQUIPMENT
    All vehicles must have the following minimum recovery equipment
    1. Suitable recovery/tow points (identified in a contrasting colour) to the front and rear of the vehicles. Standard factory fitted towing/lashing points will not be deemed as sufficient. Unless of forged construction (e.g. tow ball) all recovery points shall be of closed loop construction that cannot be pulled straight. We strongly recommend as a minimum 19mm/3/4” solid bar welded internally as well as externally to a substantial mounting point.
    2. One long recovery strap / rope at least 4.5 meters in length looped at each end.
    3. Winches if fitted and presented for self-recovery use must comply with the following regulations:

  10. SILENCING
    1. All vehicles should conform to a maximum permitted noise level. The current requirement is a maximum permitted sound level of 108dB with the engine running at 3/4 maximum speed, the sound level meter at a height of 0.5 metres above the ground (± 0.1 metre) located at 45° to and 0.5 metres distant from the exhaust. Continuous noise testing may take place during events and competitors will be advised of excessive noise. WARNING: Temporary silencers, bypass pipes and the inclusion of temporary parts to achieve silencing requirements are prohibited. Officials may refuse to carry out noise checks on vehicles utilising temporary parts in exhaust systems.
  11. FUEL SYSTEMS
    1. All fuel lines passing through the driver/passenger compartment shall be protected and, if non-metallic, be formed of internally or externally metal braided hydraulic pressure hose.
    2. Tank fillers and caps must not protrude beyond the bodywork. These must have an efficient locking action to reduce the risk of accidental opening during an accident and ensure closing after refuelling.
    3. All engines must be equipped with a positive method of throttle closing by means of external spring/springs so that in the event of failure of any part of the throttle linkage the throttle(s) are sprung closed. Vehicles which are fitted with electronic throttle control as standard original manufacturer’s equipment are exempt from this requirement.
    4. The use of fuel additives and octane boosters and aviation fuel is prohibited.

    2. The use of mesh screens instead of a windscreen will not be acceptable and will need to be covered or replaced with a suitable sheet of plastic to afford protection from branches entering the cab. Temporary screens of this type must remain for the entire event and be replaced should they get broken. We will accept a small letterbox sized slot in the plastic to allow minimum vision in event of water or mud covering the screen. We would also advise competitors in such cases to carry sufficient water and cleaning material to maintain clear vision.
  17. SEATING
    1. There must be two securely mounted seats that must not tilt unless it is a production seat fitted with a suitable locking mechanism preventing its independent operation and the top of the seat cushions when not compressed must not be less than 150mm below the top edge of any adjacent body sides or doors.

    3. The maximum time for the driver/passenger to get out of the vehicle should not exceed 5 seconds.
  18. SEAT BELTS
    1. Safety belts must be worn at all times during competition whilst the vehicle is in motion. They must be complete units as fitted by the manufacturer or sourced from a recognised manufacturer and fitted in accordance with the manufacturer’s instructions.
    2. The minimum requirement is a three-point belt comprising one diagonal shoulder strap and one lap strap, with three anchor points on the chassis/body shell or rollover bar of the vehicle on either side and to the rear of the seat.
    3. Four point comprising two shoulder straps and one lap strap with four anchorage points on the chassis/body shell or roll over bar of the vehicle. One either side and two to the rear of the seat. Where fitted the whole harness must be worn and not just the lap belt!
  19. WHEELS, AXLES & TYRES
    1. The vehicle shall have not less than four road wheels and tyres (excluding the spare) which are fitted with tyres that are compatible with the wheels and acceptable to the organiser.
    2. The use of tyre chains is prohibited.
    3. Tyres must conform to current road use regulations. The use of open tread tyres or dumper tyres is prohibited.
    4. Tyre size must not exceed 40” physical diameter when inflated to a minimum of 10psi measured horizontally on level ground.
    5. A spare wheel is not a mandatory requirement but, if carried, must be securely fastened.
    6. Wheel spacers may be used up to a maximum of 30mm in thickness.
    7. Portal axles are now permitted in club events unless otherwise specified in the event regulations.
  20. ROLL-OVER PROTECTION
    1. It is strongly recommended that all vehicles be fitted with MSA specification roll over protection.
    2. No vehicle will be allowed to compete without some form of rollover protection, although a manufacturer’s correctly fitted hardtop or Truck-cab shall be deemed sufficient.
    3. Vehicles with soft or open tops must either:
      • Fit as a minimum a roll hoop to current MSA standards and both Driver and Crewperson must wear crash helmets complying with current CSW regulations on helmets.
      • Fit as a minimum a roll hoop to current MSA standards with the addition of a hard panel above the cab seating area. The hard panel should be of solid flame retardant material and may be made removable but must be permanently and securely fixed for the duration of any event.
    4. THE STRENGTH AND SECURITY OF THE MOUNTINGS OF ROLLOVER PROTECTION ARE OF PARAMOUNT IMPORTANCE. Roll over bar materials should comprise cold drawn seamless carbon steel, minimum yield strength 350N/sq.mm. An alternative material is BS1387 medium weight blue band, minimum dimensions being 44.30mm x 3.2mm. For full details of current MSA specifications please refer to the current MSA Blue Book.
  21. HELMETS
    1. Helmets whilst not currently compulsory for Terra Tag events are strongly recommended (for both driver and navigator). We strongly recommend helmets to the standards specified in the current MSA Blue Book but will however also accept crash helmets that are suitable for use on the road to the following specifications:
      • FIA 8860-2004
      • SNELL SA2005
      • SNELL SA2000
      • SNELL SA2010

      • BS 6658 TYPE A/FR
      • BS 6658 – 85 TYPE A
      • This means that if your helmet is fit to be used on the road on a motorcycle then this WILL be acceptable but this may be withdrawn in the near future.

        For the present we accept helmets to the standard: ECER22-05 but this may be withdrawn in the near future. (TYPE B IS NOT ACCEPTABLE)

        Please protect your helmet from external damage by using a helmet bag or similar, chips within the outer laminate of the helmet may make it unsafe and unusable.

        Regulations as detailed above are the MINIMUM required.

        Version 3 amended April 2016
