AUTO CYCLE UNION HANDBOOK 2009 TRIALS
Trials
The National Sporting Code of the ACU and these Standing Regulations shall apply to all Trials
together with the Supplementary Regulations and any Final Instructions issued for individual
events.
Description
A Trial is a test of riding skill and balance over a variety of observed natural obstacles with
riders incurring penalties for footing or for failing to fulfil other conditions.
INFORMATION REGARDING AUTHORISATION AND LAND USE
Most events depend on goodwill from landowners, local authorities, nearby residents and other users
of the countryside. For the continuance of orderly motorcycle sport, a Code, formulated by LARA has
been adopted by the ACU. The Code for events with no speed element is reproduced below and will
supplement the Standing Regulations. It is to be noted that where necessary disciplinary action will be
taken if the Code is not fulfilled.
1 Any competitive event that is routed along, or across, footpaths or bridleways must be
endorsed in advance by the Highways Authority for the area, unless the route of the event is
on a highway of higher status.
2 The Organiser is responsible for obtaining authority from the landowners over whose the
event passes, unless the route of the event is on a highway of higher [EC1]status.
3 Where the event requires use of public highway, [EC2]organisers must ensure that the Motor
Vehicles (Competitions and Trials) Regulations 1969 are strictly adhered to. Events requiring
authorisation must obtain this through the RAC Motor Sports Association, Authorisation
Dept.
4 The Organiser is responsible for ensuring the event meets all requirements of the Road Traffic
Act 1988 and the Statutory Instruments made thereunder.
5 The regulations, final instructions of an event should display the following sign: – “This event
is routed along and/or across public rights of way. Competitors must exercise caution and
reduce their speed accordingly near other path users. Be especially careful near horses. Slow
down, stop and switch off your engine if necessary”.
6 The Organiser should appoint an officer responsible for event liaison. The Liaison Officer
should, if appointed submit his name and address to the local Highway Authority, the Parish
Council, the Police and landowners over whose land the event passes. The Liaison Officer will
thoroughly investigate any complaints and try to resolve any problems arising from the event.
7 Wherever possible the Liaison Officer should maintain good relations with other path users in
the area such as horse-riders, walkers, cyclists, recreational motoring groups and orienteers.
The Liaison Officer should notify these groups in advance of an event where they are known
to him.
8 All competitors must follow the Country Code.
9 Ensure that all aspects of the ACU Environmental Code are adhered to.
10 Supplementary regulations should include either a map reference or a postcode relating to the
venue in order to assist the Emergency services.

The Start and Finish of each Observed Section or Sub-Section will be clearly defined, with the Section
Begins and Section Ends identified as such.
Sections and Sub-Sections shall be numbered or lettered and ridden in the correct sequence unless
otherwise instructed by the organisers.
A rider failing in a Sub-Section must restart in a forward direction from the Sub-Section in which he
has failed.
To qualify as a finisher and be eligible for an award, the competitor must have attempted at least 75%
of the sections.
TSR 19 PUNCHCARDS
If punchcards are used, the onus of looking after these rests entirely on the rider and only the
rider/passenger may present the punchcard to the observer. Any disagreement over the score
punched, or errors must be reported to the Secretary of the Meeting immediately upon completion of
the event. The Observer must be informed that this action is being taken as any error not verified by
the Observer shall not be accepted. Refusing to have the card punched, deliberately disfiguring or
losing the punch card will result in disqualification for which no protest will be accepted. Deliberately
disfiguring a punchcard, or refusing to allow it to be punched, will result in disqualification.

An Observer is an assistant to the Clerk of the Course appointed to judge a competitor’s performance
in an Observed Section. No protest or appeal can be accepted against a judgement of performance
made by an Observer, however, a protest may be accepted against any breach, or misinterpretation of
the Regulations.
A mistake made by an Observer may be corrected by the Observer with the approval of the Clerk of
the Course.
TSR 21 INSTRUCTION TO RIDERS

such a meeting.
TSR 22 METHOD OF MARKING
A machine will be deemed to be in an Observed Section or Sub-Section when the front wheel spindle
has passed the ‘Section Begins’ Card and until the front wheel spindle has passed the ‘Section Ends’
Card. Marks will be lost as follows:

10 For missing a section or failing to have punch card marked.
Graded Hills.Where a Section is to be termed a ‘Graded Hill’ a notice to that effect must be displayed
at the Section Begins, and the following shall apply: – Numbered boards must be placed at defined
places along the Section, in order that a rider’s performance may be determined. Marks will be lost in
a decreasing manner from 5 to 0 depending on the distance a rider can traverse the Section without
failure. The front wheel spindle is the part of the machine to be used in assessing the distance traversed.

ground or the rider benefits from any part of his body leaning on an obstacle (tree, wall etc.), without
stopping the progress of the machine.
Footing outside the lateral limits of a Section does not constitute a failure but should simply be classed
as footing

both of the rider’s feet are on the ground at the same side of, or behind the machine.
e) A rider is requested to leave the section by the observer for “unnecessary delay”.
f) A machine does not stay within the intended limits of the section and within each marker.
g) If any wheel of the machine crosses any boundary tape or marker whether the wheel be on the
ground or airborne before the front wheel spindle passes the “Section ends” sign.
h) The rider is held responsible for displacing a flag, marker or support etc.
i) Travelling in a forward direction against the direction of the Section.
j) The machine or rider receives outside assistance.
k) A rider or person having an interest in a rider’s performance, who in any way alters the
severity of a section without the authority of an official.
For all trials other than those for which Championship Regulations apply the organiser may, with the
agreement of the Permit Issuing Authority, apply a time limit to each section. The time allowed must
be the same for each and every Section and the penalty for a rider not completing the Section within
that time would be failure. If a time limit is to be applied to the Sections then this must be clearly
stated in the Supplementary Regulations.
