该法规规定了美国境内卡车及牵引车驾驶室车窗的构造标准。核心要求包括：除装甲运钞车外，每辆卡车/牵引车在驾驶室两侧至少各有一个车窗；每个车窗最小面积需达1290平方厘米（约33x45厘米矩形）；角弧半径不超过152毫米；长方形长轴与车辆停放平面夹角不超过45度。若驾驶室设计为折叠门或无门窗开口，则相应位置无需安装车窗。此规定直接影响跨境陆运车辆的合规准入与查验风险。
Each truck and truck tractor (except trucks engaged in armored car service) shall have at least one window on each side of the driver's compartment. Each window must have a minimum area of 1,290 cm 2 (200 in 2 ) formed by a rectangle 33 cm by 45 cm (13 inches by 17 3/4 inches). The maximum radius of the corner arcs shall not exceed 152 mm (6 inches). The long axis of the rectangle shall not make an angle of more than 45 degrees with the surface on which the unladen vehicle stands. If the cab is designed with a folding door or doors or with clear openings where doors or windows are customarily located, no windows shall be required in those locations.
