畜牧/农业设备和其他缓慢移动的工具 机器，无论是自动推进的还是牵引的，都经常在两个方向之间移动 不连续的操作站点。运输可能涉及移动 在地面速度低于40 km/h（25 km/h）的公共道路（基础设施）上 英里/小时）。本标准提供了一种识别此类慢速移动的方法 与在此类公共道路上行驶的第三方通信的设备 关于此类设备相对于其他车辆的相对速度 公共道路。本标准确立了定义独特识别标志慢行标志的规范 车辆标志（SMV标志），仅用于低速机器（车辆），在操作或 在公共道路上行驶。本标准规定了本标准的要求和应用。这个 目的是向第三方传达低速车辆的低速能力 使用公共道路的车辆。SMV标志的主要用途是畜牧业工具 但也可与其他以低于40公里/小时（25英里/小时）的速度行驶的机器或车辆一起使用 在车速在40 km/h之间的车辆上与速度信息符号（SIS）结合使用 （25英里/小时）和65公里/小时（40英里/小时）。

Implements of husbandry/agricultural equipment and other slow moving machines, either self-propelled or towed, are often moved between operational sites that are not contiguous. Transport may involve moving on public roads (infrastructure) at ground speeds less than 40 km/h (25 mile/h). This standard provides a means of identifying such slow moving equipment to communicate to third parties traveling on such public roads as to the relative speed of such equipment to other vehicles utilizing the public roads.This Standard establishes specifications that define a unique identification emblem, the Slow-Moving Vehicle Emblem (SMV Emblem), to be used only for slow-moving machines (vehicles), when operated or traveling on public roads. The requirements and applications of the standard are defined in the standard. The purpose is to communicate to third parties the slower speed capabilities of the slow-moving vehicle to other vehicle(s) using public roads. The primary application of this SMV emblem will be with implements of husbandry but may be used with other machines or vehicles that travel at speeds less than 40 km/h (25 mile/h) and in combination with a Speed Information Symbol (SIS) on vehicles which travel at speeds between 40 km/h (25 mile/h) and 65 km/h (40 mile/h).
