Agricultural tractors conformity to the Brazilian traffic lighting and signaling legislation

ABSTRACT: Increasing the agricultural machinery visibility makes public roadways traffic safer by reducing the number of accidents and their severity. The study aimed to verify the compliance of new agricultural tractors with Brazilian law, given by, CONTRAN Resolution N° 454, NR12 and NR31, regarding the presence of lighting and signaling elements for traffic. The study was carried out in agricultural machinery dealers of seven brands, corresponding to 50 different models of new wheeled agricultural tractors. The items that was not present in total tractors sample are the rear position lamp, the reverse light and the rear retro-reflector. In addition, only one of the seven brands studied showed complete compliance with evaluated elements. Although, the Brazilian legislation specify the presence of lighting and signaling items for agricultural tractors traffic, there is not fully comply on tractors models analyzed and the Brazilian law are not homogeneously met by the agricultural tractor manufacturers in the verified sample, what can be leading to tractors traffic accident occurrences.

摘要：提升农业机械的可视性，可通过减少道路交通事故的发生数量并降低事故严重程度，进而提升公共道路交通的整体安全性。本研究旨在验证新型农用拖拉机是否符合巴西相关法规要求，即巴西国家交通委员会（CONTRAN）第454号决议、NR12及NR31中关于拖拉机交通照明与信号标识元件配置的相关规定。本研究的样本采集自7个品牌的农机经销商，涵盖50款不同型号的新型轮式农用拖拉机。在所采集的全部拖拉机样本中，缺失的配置包括后位置灯、倒车灯及后回复反射器（retro-reflector）。此外，在所研究的7个品牌中，仅有1个品牌的拖拉机样本完全符合本次评估的各项配置要求。尽管巴西立法明确要求农用拖拉机需配备交通照明与信号标识装置，但本次分析的拖拉机型号并未完全符合相关规定，且经验证的样本中，各拖拉机制造商对巴西法规的合规程度并不统一，这可能会增加拖拉机道路交通事故的发生风险。
