Abstract

Le conducteur de n'importe quel véhicule tractant une remorque est confronté à un problème de direction lorsqu'il souhaite faire une marche arrière. En outre, tout véhicule tracteur ayant une cabine surélevée rend la remorque presque invisible pour le conducteur et ce problème est accentué lors de la conduite d'un minibus, d'un camion ou d'un bus. Cette invention a l'avantage d'éliminer ou de réduire au minimum ces problèmes grâce à la remorque proposée.
