美国交通部 NHTSA 提议无人驾驶汽车可选装青色标志灯：联邦公报10月26日刊出拟议规则，意见期至11月25日
华盛顿——美国交通部（DOT）下属国家公路交通安全管理局（NHTSA）提议修订联邦机动车安全标准第108号（FMVSS No. 108），允许配备自动驾驶系统（ADS）的车辆选装青色标志灯，用灯光向其他道路使用者表明车辆正由自动驾驶系统驾驶。该拟议规则制定通知10月26日正式刊登于《联邦公报》（91 FR 67243，文件号 FR Doc. 2026-21794，案卷号 NHTSA-2026-1519，规则号 RIN 2127-AM70），公众意见须在2026年11月25日前提交。
NHTSA 说明，这不是强制要求：该局表示，目前信息不足以认定所有自动驾驶车辆都必须装这种灯，因此采用「装了就要达标」的口径——厂家自愿安装的青色标志灯必须符合统一规格，没有自动驾驶功能的车辆则禁止安装此类标志灯。该局称，统一规格可以避免各厂家推出互不一致的灯光造成驾驶人、行人与骑行者混淆与分心，并为厂家提供明确的合规依据。
按拟议规格，青色以 SAE J578 定义的蓝绿色为准，与行业标准 SAE J3134 一致；车辆前方、每一侧与后方各装一至两盏，全车最少四盏、最多八盏，从每个方向都至少能看到一盏；最低安装高度为离地15英寸；点亮时保持常亮、不闪烁，是否允许闪烁用作信号，该局另行征求意见。拟议文本还提到，Mercedes-Benz 曾向 NHTSA 提出标志灯建议，并于2023年至2025年在加州用五辆车做了两年的道路验证，收集其他道路使用者与装灯车辆互动的数据。
同一通知还提出其他几项修订：整体式大灯的测试电压改为按灯上标注的功率执行；取消垂直排列大灯时低光束须在高光束之上的要求；对没有手动驾驶操纵装置的自动驾驶车辆，将转向灯、危险警告灯与远近光切换的手动操纵要求、以及部分仪表指示灯要求，限定只适用于带手动操纵装置的车辆。NHTSA 表示，这些修改意在删去对无方向盘、无踏板车辆没有实际安全作用的要求、减轻不必要的负担，意见可通过 regulations.gov 按案卷号提交。
NHTSA Proposes Optional Cyan Marker Lamps for Driverless Vehicles: Federal Register Rule Published October 26, Comments Due November 25
WASHINGTON — The National Highway Traffic Safety Administration (NHTSA), part of the U.S. Department of Transportation (DOT), is proposing to amend Federal Motor Vehicle Safety Standard No. 108 to allow vehicles equipped with an Automated Driving System (ADS) to carry optional cyan marker lamps indicating that the vehicle is being driven by the automated system. The notice of proposed rulemaking was published in the Federal Register on October 26 (91 FR 67243, FR Doc. 2026-21794, Docket No. NHTSA-2026-1519, RIN 2127-AM70), and comments are due no later than November 25, 2026.
NHTSA stresses that the lamps would not be mandatory. The agency says it lacks sufficient information to conclude there is a safety need to require the lamps on all ADS-equipped vehicles, so it is proposing an 'if equipped' standard: any cyan marker lamp a manufacturer chooses to install must meet the proposed specifications, and installing such lamps on vehicles without ADS functionality would be prohibited. Standardizing the lamps, the agency says, would keep differing designs from confusing or distracting drivers, pedestrians and cyclists, and would give manufacturers regulatory certainty.
Under the proposal, the color would be cyan, the blue-green defined in SAE J578, consistent with industry standard SAE J3134. A vehicle would carry one or two lamps on the front, on each side and on the rear — a minimum of four and a maximum of eight in total, with at least one visible from every direction — mounted at least 15 inches above the ground and steady-burning when activated; NHTSA is separately seeking comment on whether flashing should be allowed for signaling. The notice notes that Mercedes-Benz presented marker-lamp recommendations to NHTSA and conducted a two-year on-road validation in California from 2023 to 2025 using five vehicles.
The same notice proposes several other changes: testing integral-beam headlamps at the voltage marked on the lamp, removing the requirement that lower beams sit above upper beams in vertical headlamp arrangements, and limiting manual-control requirements for turn signals, hazard warnings and beam switching — along with certain telltale requirements — to vehicles with manually operated driving controls. NHTSA says the changes are intended to remove requirements that serve no safety purpose in vehicles without a steering wheel or pedals. Comments may be submitted through regulations.gov under the docket number.
