考美国A照看这个就行了！来自美国卡友马丁的真实考题分享~

自从美国卡友马丁的视频在论坛内发布后，论坛里面刮起了一股美国卡车风。也有很多的卡友私信马丁在美国开卡车的各种问题。其中驾照考试问题是大家问的最多的，包括考试题都考啥？我们看不懂怎么办？

针对于这种情况，卡友马丁给大白发来了一份美国真实的A照考题，卡友们可以来看看学习一下~让我们在这里感谢马丁所提供的资料！这些题目的翻译都是马丁和他的爱人一条一条翻译的，足可见这些资料的珍贵！

考题中的刹车题、复合题、基础题是A照必考的，BUS如果不考的话可以不看，混合题的意思就是把所有的题目都打乱了，作为自己测试用，以前只有三套考题，所以很多人只背答案来考试，现在考试都使用电脑版，每次都是随机出题，所以混合题就更为重要了。

前排高能提醒！海量考题来袭！由于篇幅较长，大白会分段进行发布~
