Concern over electronic signals leads Calif. to reverse mandate for reflective vehicle windows

Calif. nixes rule mandating reflective car windows

SACRAMENTO, Calif. — California air regulators are reversing a mandate that would have required sun-reflecting glass to be installed on all new vehicles sold in the state.

The California Air Resources Board adopted the rules last year to reduce the amount of air conditioning vehicles use, and therefore cut their fuel consumption. But critics complained the new windshields might block cell phone signals in remote areas.

Law enforcement officials also expressed concern that the windows would interfere with the electronic signals from ankle bracelets worn by paroled felons.

The board reversed the rules Thursday. They had been scheduled to go into effect in 2012.
