TITLE: FMVSS INTERPRETATION
TEXT: This is in reply to your letter of April 26, 1972, inquiring whether you are required to use "laminated safety glass" in the forward-facing window of a pickup cap. You indicate that this window is below the roof line of the cab of the pickup, immediately behind its rear window.
Under Federal Motor Vehicle Safety Standard No. 205, "Glaring Materials", (49 CFR 571.205, copy enclosed) windows in campers, pickup caps, pickup canopies, and pickup covers must be manufactured of safety glazing material specified in the standard, Forward-facing windows such as the one you describe must be manufactured of either AS1, AS2, AS3, AS4, or AS5 glazing materials, as those materials are described in the American National Standards Institute Test E26.1-1966. Materials other than "laminated safety glazing" may be used to meet each of these "AS" categories, and we refer you to ANS Test 226.1 for specific requirements.
