摘要总结AI 辅助解读
该条款规定美国境内所有巴士、卡车及牵引车必须配备速度表，显示英里/小时或公里/小时。在80 km/hr（50 mph）速度下，误差不得超过±8 km/hr（5 mph）。此为车辆设备技术标准，主要约束车辆制造商与合规性检测环节，对跨境物流运营方的日常申报、舱单传输及通关流程无直接程序性改变，建议作为背景知识了解即可。
Each bus, truck, and truck-tractor must be equipped with a speedometer indicating vehicle speed in miles per hour and/or kilometers per hour. The speedometer must be accurate to within plus or minus 8 km/hr (5 mph) at a speed of 80 km/hr (50 mph).
