该条款规定了美国公路运输中特定危险品的特殊标牌要求。核心内容包括：(a) 运输7类放射性物质（公路路线控制量）的机动车，必须使用符合§172.527规定的方形背景RADIOACTIVE警告标牌；(b) 符合§173.315(m)规定的护士罐车（nurse tank），若因阀门、配件等阻碍导致无法正确放置和显示标牌，则装有这些部件的一端可豁免挂牌。此规定旨在平衡安全警示与实际操作可行性。
- (a) Each motor vehicle used to transport a package of highway route controlled quantity Class 7 (radioactive) materials (see § 173.403 of this subchapter) must have the required RADIOACTIVE warning placard placed on a square background as described in § 172.527.
- (b) A nurse tank, meeting the provisions of § 173.315(m) of this subchapter, is not required to be placarded on an end containing valves, fittings, regulators or gauges when those appurtenances prevent the markings and placard from being properly placed and visible.
