RULES AND REGULATIONS
MCC events cater for a range of vehicles and classes and are operated within professional sporting guidelines.
Our events are run in accordance with the Standing Supplementary Regulations (SSRs.) Each event also has its own Additional Supplementary Regulations (ASRs), which can be found with the details for each event.
Our rules and regulations are quite long, but don't let that put you off. Once you understand how your class operates it's fairly straight forward.
Here's a quick guide:1. Make sure that you have entered the event in the correct class for your vehicle.
2. Read and comply with the ASRs for the event.
3. Make sure your vehicle has the correct tyres. There is a list of permitted tyres in section 4 of the SSRs.
4. The rules for motorcycle tyres are defined in the SSRs with additional rules here.
5. Make sure that your vehicle is fully road legal.
6. Follow the instructions in the event route book, available online before the event starts.
7. Comply with the instructions of club officials.
Cars must be two-wheel drive, non-commercial and fitted with road tyres from a prescribed list. Most motorcycles and sidecars are required to be fitted with trials tyres front and rear, though there are exceptions to this for certain classes.
Good vehicle choices are hotly debated by club members – some will recommend the thrill of bouncing up slippery hills using horsepower whilst others will advocate lightweight vehicles with superior tractability and manoeuvrability. Increased ground clearance and protection for exposed parts are popular modifications for competitors driving our classic trial sections.
Vehicle classes are intended to serve as a handicap system for drivers and riders of vehicles deemed to have an advantage over a typical road going vehicle. Drivers of front-wheel powered cars can expect no handicap, whilst drivers of rear-wheel drive ‘trials special’ cars with rear-mounted engines can expect to compete under the full weight of class eight.

Additional information for car classes
A production car, which includes production saloons and production sports cars, is any car that is or has been on sale in a catalogue as a completed, road going vehicle, and is or was available through normal retail dealer outlets. A production car, or variants or copies thereof must not at any time have been available as a kit car. The MCC reserves the right to reclassify any make or model of car, although meeting the above criteria, into a non-production or modified class. Four-wheel drive vehicles are not permitted. Any two-wheel drive vehicle from a range that includes a fourwheel drive variant on UK general catalogue sale may compete provided either (a) the vehicle construction is of purely monocoque design, i.e. there is no chassis or (b) the vehicle has a wheelbase of less than 2225 mm.
Class Oa) Any vehicle is eligible (subject to acceptance by the Clerk of the Course and complies with item d below).
b) Run on a modified course of a less damaging nature.
c) Vehicles and entrants must comply with the SSR. d) For practical reasons, the number of entries in this class may be limited.
Classic Road Trial (Class R)a) A test of hill climbing ability, navigation, and timing.
b) Run on a route with non-damaging surfaces, the majority on sealed surfaces.
c) Open to any road legal motorcycle or two-wheel drive motor car, subject to the Clerk of the Course’s decision on eligibility/desirability of any vehicle.

f) Motorcycles to comply with ACU regulations.
g) Cars to comply with Motorsport UK regulations.
h) With the exceptions of the above, vehicles and entrants must comply with the SSR. 3.4
Navigation The club uses a written roadbook method of navigation which usually necessitates a passenger (car drivers) or a roadbook holder (motorcyclists). GPS is welcome as an aide-memoire, but given that our routes vary from year-to-year (and power supplies can fail) this should not be relied upon as a primary method of navigation.A typical instruction might read: In 0.3 miles at X L DP Sutcombe. In 1.1 miles L at X DP Holsworthy (QQ). Which translated, is understood to instruct: In 0.3 miles at the cross-roads, turn left onto the road where a direction post reads ‘Sutcombe’. At the cross-roads in a further 1.1 miles, turn left onto the road where a direction post reads ‘Holsworthy’, and proceed very quietly. Small (c.5-inch), square direction signs are used at some junctions in rural locations to assist with navigation. These will usually read ‘L’, R’, ‘SO’ or ‘QQ’ as required. Roadbooks are printed in A4 size and are made available to competitors up to two weeks before. They also contain important information concerning restarts, observed tests and essential final instructions required to keep competitors safe and organised.
