挂车倒车技巧口诀是：
1、半挂车倒车时转向盘转动方向与单车倒车方向相反。
2、急弯曲路况时，降低车速。
3、左弯曲路时，半挂前外侧冲出牵引车。
4、右弯曲路时，半挂内后侧贴近道路中心线。
5、在往后边倒车的时候不要心急，一定要观察倒车镜，找好车的距离感和方向感。
扩展资料
倒挡、全称倒车挡，汽车中的三大标配挡位之一，在挡位操纵台上的位置标识为R，目的是使车辆能够后退，属于一种特殊的行车挡。
倒车挡是所有汽车均有的一种行车挡位，一般都配有大写字母R的标记，挂倒挡后车辆的行驶方向会与前进挡的相反，实现汽车倒退。
倒挡的功能作用单一简单，就是使车辆反方向行驶、实现倒退，但这一功用对任何汽车而言都不可或缺。在手动挡车型中，倒挡还具有坡道刹车功能，在下坡段停车可以通过挂倒挡方式将驱动轴机械锁止。

半挂倒车的具体技巧：
1、半挂车与邻车并排确认与邻车相距约1米,确认后面安全后直线倒车,当车辆后保险杠并排时停车。
2、右转方向盘,倒车至目标位。车停时，将方向盘向右打到底。稍微放松制动踏板,利用半挂车蠕动功能进行倒车。车身左侧面到达某点延伸直线上时停车。
3、左转方向盘,使轮胎回正之后倒车。在车停时,回转方向盘使轮胎回正;缓慢地直线倒车,左后轮达到停车位外侧白线时,停止倒车。
4、将车向右边靠近，将半挂车方向盘向左打到底,缓慢退行;在车辆与路肩平行之前,回转方向使车辆回正,将车辆停在与路肩平行的位置（半挂车属于大型车辆，停车时要小心擦碰，不要与后车碰撞）。
