mentioned.
[Material Testing Certificate to be carried in original at main event.]
Beding Strength & Stiffness criteria must be satisfied for material other
than steel too.
(Check Calculations)
All rigid parts of the vehicle must have minimum 8 inch clearance from
the ground. Measurement of the clearance with all parts (pedal, chain,

mounted to the wheel/wheel hub or parts which can rotate shall not be
taken into consideration.
All the drivers’ body parts, which are not in direct contact with the vehicle,
must have at least 3 inches clearance from the frame in all static &
dynamic conditions.
Both the drivers must maintain the 3 inch clearance comfortably between
each other in all static & dynamic conditions.
The frame should be capable to protect the drivers from the ingress of
debris etc during running on different tracks.
There must be individual seats for both the drivers. Use of cushions or
pads directly mounted on the frame will not be considered as seat.
The frame must be capable of keeping the occupants safe at the time of
