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
