Dan just sent me this update on rules rewrites. Even if I end up listed as the "author" -- not it! Please all take a moment to thank Dan for his long hours of work helping us get the rules so early in the season. It's the best-ever effort to get us the rules - and I do thank you, Dan.
This is the final rewrite to the two open 2011 rules issues. As before, the bold print indicates a change in the rule from previous releases.
3.A.3 Driver’s Helmet Support
Lateral Movement: The seat, roll cage structure or suitable restraint system, such as a restraint net, swing away bar or similar such device, shall provide restriction to lateral head movement of less than 2 in. per side inclusive of structure deflection, and at a minimum extend to the forward most portion of the helmet see Section 3.B.1.
3.U WINDOWS AND WINDSHIELDS:
All non-stock windows and windshields shall be made of shatter-resistant plastic, such as polycarbonate (Lexan), and shall provide 120 degrees of adequate vision forward. On all open body cars a windshield is recommended, but shall not restrict driver entrance or exit. In all classes where a headrest fairing is permitted, the windshield may sweep around the driver’s head and connect to the fairing on either side (see 3.E Driver’s Compartment rule concerning sharp edges).
All windshield wiper blades and arms shall be removed. On front and rear windows, retaining tabs or straps are required over 175 MPH.
Vehicles with T-Tops or moon roof panels shall have the panels retained with tabs or straps.
All vehicles over 250 MPH shall replace all non-laminated safety glass windows with polycarbonate material. All other glass, such as headlights, must be covered with SAFETY film.
Beginning January 1, 2012 all vehicles in classes where the record exceeds 200 MPH must have all non-laminated safety glass windows replaced with polycarbonate material.
Beginning January 1, 2012 all vehicles with “frameless” side windows, regardless of speed, must have all non-laminated windows constructed of polycarbonate material.
Additional bracing must be installed to prevent window blowout or collapse.
