The standard locations shall be
as follows:
A. Formula and Sports Racing Cars–In proximity to the right-hand
member of the roll bar, but in a location so that it cannot be operated
accidentally. It can be mounted on a bracket welded to the
inside of the upright member or mounted so that the operating lever
or knob is outside of the body panel immediately in-board of the
upright member. This is the standard location on Formula cars built
to the Constructor’s Association requirements for Formula 1.
B. Closed Sports Racing Cars, Production Cars, Improved Touring and
GT Cars–In front of the windshield on either the cowl or on top of
the fender, but close enough to the windshield to be accessible
if the car is overturned. Alternatively, it may be mounted below
the center of the rear window or on a bracket welded, clamped
or bolted to the roll cage or dash, easily accessible through the
open window. (Drilling of holes in roll cage to attach the bracket is
prohibited.)
C. Open Production, GT, and Improved Touring Cars–May exercise a
choice among the above locations.
