On Sep. 1, 2009, NHTSA published a proposal to require automatic reversal systems on express-up windows. As proposed, the requirements would apply to passenger cars, MPVs, and trucks with a GVWR of 4,536 kilograms or less starting 24 months following publication of the final rule (i.e., 2013MY).
Comments on the proposal are due November 2, 2009.
