Barrier System. A device installed on the concession racing kart track which defines the
boundaries of the track and/or run-off areas and whose primary purpose is to contain the vehicles
within pre-determined boundaries.
Concession Go-kart. A motorized vehicle with four wheels that is driver controlled with respect
to acceleration, speed, braking and steering. This vehicle operates within the containment system
of a defined track and is intended to simulate competitive motor sports for members of the
general public for a fee. A concession go-kart has a maximum capacity of two persons and no
cargo capacity.
Concession Racing Kart. A motorized vehicle with four non-aligned wheels in contact with the
ground, two of which control the steering while the other two transmit the power. A concession
racing kart is a vehicle, with or without bodywork, controlled by the driver with respect to
acceleration, speed, braking and steering. Concession racing karts are classified by speed and
are driven and/or raced on tracks. Speeds for Class One and Class Two concession racing karts
shall not exceed 35 mph and 55 mph respectively. Speed qualification of concession racing karts
shall be based upon speed measured on a flat and level track surface.

of karts and managing all track operations.
Discussion. Specifically excludes similar devices that are intended for use in an amusement
facility setting (concession go-karts), race schools or sanctioned racing (racing karts), devices
such as electronically or rail guarded amusement rides and bumper cars or other similar
amusement devices that operate under circumstances where there is no defined direction of
travel.
Driver. The person who manipulates and controls the direction of travel, braking and speed of
a concession racing kart.
In order to drive a Class One concession racing kart, the driver shall have either attended a
class and taken and passed a practical test to establish his or her competency or be 18 years of
age or older and hold a valid internationally recognized drivers’ license.
In order to drive a Class Two concession racing kart, the driver shall either hold an applicable
valid competition license from a recognized motor sport sanctioning body, have taken part in a
minimum of six competition events in a Class One concession racing kart or have attended a
class and taken and passed a practical test.
In all cases the driver (and his or her parent/legal guardian if the driver is 18 years old) shall
sign a full release and waiver of liability and acknowledgement that he or she are taking part in
competitive motor sports and understands the risk of possible injury and/or death.
Fun Kart. A motorized vehicle with four wheels, sold commercially as consumer goods and
intended for private personal recreational use by the consumers for off-road use on suitable
terrain, as recommended by the manufacturer.
Lapping Session. Any laps driven at a concession racing kart facility in either a race or practice
session.
Pit. A defined area for the purpose of drivers getting in and out of the vehicles at the beginning,
during or end of any lapping session and where refueling of concession racing karts may take
place.
Race Kart. A motorized vehicle with four wheels designed for use in either Sanctioned Racing
on tracks, streets, or other areas of competition or in a Racing School facility. Racing Karts are
