HERE
Notwithstanding anything contained in these
specifications, the machine examiner, scrutineer and/or Club Committee shall
have the right to exclude ANY vehicle from competition at any time, if in
his/her/their opinion, the vehicle is not track worthy or could become a danger
to other competitors.
Likewise, a driver who is not considered fit for any
reason to drive a vehicle, shall be disqualified from driving by the steward
and/or clerk of the course.
Notwithstanding any design detail contained in these
specifications, or approvals given, the Club Committee and members accept no
responsibility for the safe operation of any vehicle or component manufactured
under these rules.
Each member of the Club accepts that it is a condition of
membership that they indemnify all other members of the Club against any injury
or damage to their own or others property which may occur during race meetings.
This indemnity applies even if the above described injury
or damage is caused by failure of equipment, (which has or has not been approved
by the Club Committee or passed at scrutineering), or unsafe driving habits of
other competitors.
It must be emphasized that the specifications lay down
standards and dimensions to be achieved in the manufacture of a racecar and
approvals that must be gained prior to use of such racecar. This in no way
places the responsibility of any matter covered in the Specification upon
members of the Club.

competitor whilst competing.
NASR
has developed and adopted a Drug and Alcohol Policy applicable to all speedway
participants commencing with the 2006/07 season (from 1st of July 2006).
The
policy outlines set procedures, including testing techniques for both drugs and
alcohol, as well as chain of evidence requirements and relevant offences and
penalties.
The
policy is based on saliva testing for drugs and was written in consultation with
the South Australian Police Department and relevant testing authorities.
Competitors,
Mechanics and Officials will be selected at random at race meetings across the
country by an independent testing agency.
It
is the responsibility of each competitor and their associated support crew to
ensure they comply with the current regulations.

website.
