The information below is extended from the details of the vehicular class system described in the Technical Regulations. It is a subset of the technical regulations and should be read referring to them, as needed. As we are regulated by the MSA we recommend you also refer to the current Year Book (referred to as the Blue Book) for vehicles and safety equipment, as this will supercede our regulations if required.
The Class for specials and ATVs (All Terrain Vehicles). Vehicles may be extensively modified, but must still conform with the Technical Regulations. Four wheel steering, slewing brakes and open centred (dumper) tyres are permitted in this class, subject to the ASRs for the event.
The amount of modifications allowed in this class are restricted but do include: changing of chassis lengths, change of spring type, change of engine and/or gearbox type. The axle choice is free.
What is not permitted:
- After market differential locking mechanisms
- Four wheel steering
- Slewing brakes
Open centred tyres (subject to prevailing ASRs) are permitted. It is recommended an amount of bodywork be retained to give an impression of the make of the vehicle, this should be easily identifiable by the average spectator. All vehicles must conform to the current technical regulations.
Classes 3, 4 & 5
The standard RTV categories are for road-going vehicles.
The modifications are limited to: Engine conversions; power steering fitment; free choice of wheels and tyres.
The fitting of safety equipment of any type is permitted.
A front screen frame must be in place as should be a mid¬mounted roof frame when competing (this is the absolute minimum). Tyres such as those described in section 9i of the technical regulations. (open centred) are not permitted for use on RTV vehicles. A valid Road Fund Licence must be displayed for that vehicle. Auxiliary lamps and low hang¬ing bodywork (such as sills) may be removed. A FULL width front bumper must be in place.
RTV Wheelbase less than 85″
RTV Wheelbase over 85″ but under 100″
RTV Wheelbase 100″ and over.
Allows any vehicle which does not comply with the listed class specifications above such as a home built hybrid to compete in trials. It will be run over the same sections as the RTV trial. There are no wheelbase classes as found in RTV. The only restriction is that open class competitors should not be able to use fiddle brakes if fitted and will need to run on a road tyre as tyre rule 9i. applies to this category.
Frequently Asked Questions
All vehicles must be equipped with towing points front and rear. The tow ball or point must be bolted using suitable nuts and bolts of adequate size. These must accept a rope loop and be secure without requiring the use of shackles or other such attachments. On Modified vehicles where a tow-ball is used, it must be fitted so as to retain the rope, i.e. it should either be mounted with the ball facing away from the direction of pull, or, where it is mounted close to a chassis member, a trap should be formed to prevent the rope from coming accidentally detached.
Be equipped with a nylon rope of a minimum 25mm diameter. This rope must have a closed loop at each end and be of at least 4.5 metres in length. The use of chain or wire bond is prohibited. Polypropylene or hemp ropes are not advisable. N.B. Marshals may use any equipment approved by the Clerk of the Course
Code of Conduct
- Use only rights of way with known, proven or provable vehicular rights. If challenged, discuss; if not resolved, then leave as requested until the status is rechecked.
- Keep to the defined track. Detour only to pass immovable obstructions. Report any obstructions (including low branches) to the highway authority and ask a committee member to discuss it at the next meeting. Be critical of your own abilities and equipment when assessing an obstruction; it is your right to abate a non-lawful obstruction, but do not commit yourself to a bigger task than you are equipped for.
- If the route is not obvious on the ground ask. Either locally, or check on the maps held at the highway authority offices.
- Travel at a quiet and unobtrusive pace and as slowly as practicable; we recommend a maximum of 12 mph when in a 4x4 and on an Unsurfaced Right of Way (URoW). Ensure your vehicle is fully road-legal.; URoW are subject to the same laws as surfaced roads.
- When travelling in groups, keep to a small number – ideally four or less. Split larger parties up and either use a different route or allow a good interval to elapse before following.
- Do not travel on URoW when they risk being affected beyond a point of natural recovery once the weather improves. If need be, walk some or the entire route first to determine its suitability. Do not use URoW which maybe damaged by the wheel pressure applied by your vehicle.
- Avoid damage to trees, hedgerows and boundaries. Some roads carry vehicular rights but are physically too narrow for 4x4s.
- Do not practice recovery techniques on any URoW. Use a winch only with extreme caution, and use only the correct equipment and techniques.
- Be courteous to other road users – pull over and stop your vehicle for walkers, but pull over, stop your vehicle and switch off the engine for passing horses; the same courtesy should also be shown to walkers with dogs, if the dogs show the least sign of nervousness round vehicles. Thank those who move over for you.
- After consultations with Country Landowners Association and National Farmers Union HQs, “best practice” dictates that gates if they were found to be secured in an open position should be left open, and those which are found shut or swinging should be shut behind you; the landowner might appreciate being told about a gate insecurely propped open if you see them.
- Keep dogs and children under close control. Watch out for injured or trapped animals, and report all suspicious events to the landowner.
- Guard against all risks of fire. Take your litter home and that left by others if you see it, wherever practicable. Plastic bags can suffocate stock if swallowed. Help to keep all water clean. Remember that wildlife faces many threats and UROW are valuable habitats. Take special care in spring and early summer.
- Follow the Country Code, but be aware that it is for your guidance only
