7:8 WINDSHIELD, WINDOWS
Windshields and/or windows on all cars, when called for
under Class Requirements, must be of safety glass, Plexiglas,
Lexan, or other shatterproof material, minimum 1/8-inch thick.
Windshields may not be attached with self-locking fastener
buttons. In all Camping World Drag Racing Series and Lucas Oil
Drag Racing Series vehicles, windshields and/or windows must
be clear, without tinting or coloring, except factory-tinted safety
glass. In all other applications, windshield/window tint must
meet the applicable state requirements. Windshield/window
must be in good condition and free from cracks. Competition
number decals are permitted on any window, windshield or
backlite, except as noted in Class Requirements.
Tape of any kind prohibited on any windshield or window. The use of
any temporary or permanent shielding, including paint, that
obstructs the driver’s vision (e.g., blinders, staging aids) and that
is attached to the helmet, window or windshield is prohibited.
Permitted shielding not to exceed 4 inches by 8 inches is
permitted at this time provided that (a) it has a permanent
attachment to the vehicle, such that it requires tools for removal,
and (b) that the shielding is deemed safe by the driver in the
driver’s judgment and so long as the driver can demonstrate
to technical inspectors that the purpose of the modification
is to reduce distraction in the driver’s field of vision. By using
such a shield, the driver acknowledges and agrees that the
driver deems such modification safe in the driver’s judgment
consistent with the driver’s obligations in Section 1, Participant
Agreements and Administrative and Procedural Rules, set forth
above, and that the shield does not impair or interfere with the
safe operation of the driver’s vehicle. Tape, tie straps, binder
clips, hook-and-loop fasteners, glue, etc. are prohibited for
attachment purposes. Vehicle-mounted shielding is allowed to
pivot as long as it remains permanently attached. See General
Regulation 10:7.
