    1. 跟车过近 (Following too closely)
    2. 制动失灵
    3. 道路照明不足
    4. 货物过重

  2. #2

    您驾驶40英尺长的卡车，时速低于40 mph，数出与前车只有2秒。应该怎么做？

    英文原文: You are driving a 40-foot truck below 40 mph and count only 2 seconds behind the vehicle ahead. What should you do?

    1. 保持不变；2秒就够了
    2. 拉开距离并重新数，直到达到4秒 (Drop back and count again until you have 4 seconds)
    3. 拉开到6秒
    4. 加速贴近前车

    答案: B. 40英尺的卡车需要4秒（超过40 mph时为5秒），应拉开距离再数一次。

    来源: North Dakota CDL Manual (AAMVA model), Section 2, p. 43Drop back a little and count again until you have 4 seconds of following distance (or 5 seconds, if you’re going over 40 mph).

  3. #3

    要知道自己与前车有几秒的跟车距离，应：

    英文原文: To know how many seconds of following distance you have, you should:

    1. 数前方车辆完全停下来所用的秒数
    2. 查看速度表，并按每10英里/小时数一秒
    3. 等前车经过一个参照物后，数到您到达该处的秒数 (wait until the vehicle ahead passes a landmark, then count the seconds until you reach it)
    4. 用后视镜测量距离，然后数你们之间有几个车身长度

    答案: C. 从前车经过明显参照物开始，数到您到达同一地点的秒数。

    来源: North Dakota CDL Manual (AAMVA model), Section 2, p. 43To know how much space you have, wait until the vehicle ahead passes a shadow on the road, a pavement marking, or some other clear landmark.

  4. #4

    如果后车紧贴着您行驶，您不应该：

    英文原文: If a driver is tailgating you, you should NOT:

    1. 在减速或转弯前提早打灯
    2. 加大自己的跟车距离
    3. 非常平缓地减速
    4. 加速 (speed up)

    答案: D. 低速被紧跟比高速被紧跟更安全，所以不要加速。

    来源: North Dakota CDL Manual (AAMVA model), Section 2, p. 44Don’t speed up. It’s safer to be tailgated at a low speed than a high speed.

  5. #5

    被后车紧跟时，下列哪项应当避免？

    3. 让车辆保持在车道中央 (keep the vehicle centered in the lane)
    4. 骑在车道线上行驶

    答案: C. 保持在车道中央行驶，两侧才有安全间隙。

    来源: North Dakota CDL Manual (AAMVA model), Section 2, p. 44You need to keep your vehicle centered in the lane to keep safe clearance on either side.

  8. #8

    为什么不能想当然地认为桥梁和立交桥上标示的限高是准确的？

    英文原文: Why should you not assume the heights posted at bridges and overpasses are correct?

    1. 标志上的数字总是比实际高度低几英寸
    2. 桥梁遇冷升高、遇热下沉
    3. 标示高度已包含若干英寸的安全余量
    4. 重新铺路或积压的雪可能已经减小了净空 (Re-paving or packed snow may have reduced the clearance)

    答案: D. 自标示高度以来，重新铺路或压实的积雪可能使净空变小。

    来源: North Dakota CDL Manual (AAMVA model), Section 2, p. 44Don’t assume that the heights posted at bridges and overpasses are correct. Re-paving or packed snow may have reduced the clearances since the heights were posted.

  9. #9

    如果路面倾斜使车辆靠向路边的标志、树木或桥墩等物体，应该：

    英文原文: If the road tilts your vehicle toward objects along the edge, such as signs, trees or bridge supports, you should:

    1. 稍微靠近道路中央行驶 (drive a little closer to the center of the road)
    2. 开上路肩以远离路边的物体
    3. 加速快速通过，以减少靠近它们的时间
    4. 停车并倒车，找一个更平坦的地方通过

    答案: A. 路面倾斜导致路边净空有问题时，要稍微靠近道路中央行驶。

    2. 头顶悬挂的物体，如树木、树枝或电线 (overhanging objects such as trees, branches or electric wires)
    3. 其他司机的车牌以及他们车辆上的名称
    4. 该区域附近设置的称重站标志和限速标志

    答案: B. 下车查看头顶障碍物，因为倒车时很容易看漏。

  11. #11

    如果卡车右转时不得不转入另一车道，应在完成转弯时外摆，并且：

    英文原文: If a truck cannot make a right turn without swinging into another lane, you should turn wide as you complete the turn and:

    1. 先向左大幅外摆
    2. 让前轮远离路缘
    3. 让车尾紧贴路缘 (keep the rear of your vehicle close to the curb)
    4. 转弯时加速

    答案: C. 车尾靠近路缘可以阻止其他车辆从右侧超车。

    来源: North Dakota CDL Manual (AAMVA model), Section 2, p. 44Keep the rear of your vehicle close to the curb. This will stop other drivers from passing you on the right.

  12. #12

    英文原文: If you must cross into the oncoming lane to make a turn and a vehicle approaches, you should NOT:

    1. 给它留出通过或停下的空间
    2. 留意迎面驶来的车辆
    3. 等到能完成转弯再动
    4. 为它倒车让路 (back up for it)

    答案: D. 不要为来车倒车，因为可能撞到身后的人。

    来源: North Dakota CDL Manual (AAMVA model), Section 2, p. 45However, don’t back up for them, because you might hit someone behind you.

    大型车辆在路口左转时，应在何时开始转弯：

    英文原文: When making a left turn with a large vehicle at an intersection, you should start the turn:

    1. 一进入路口就转
    2. 从右侧车道转
    3. 到达路口中央之后 (After reaching the center of the intersection)
    4. 在停车线之前

    为什么空载货车可能撞上满载货车能通过的天桥？

    英文原文: Why can an empty cargo vehicle hit an overpass that a loaded one clears?

    1. 空车更长
    2. 空车开得更快
    3. 满载车更宽
    4. 空车车身比满载车高 (An empty vehicle sits higher than a loaded one)

    答案: D. 货物重量会压缩悬架；空车时车身更高。标示的限高也可能有误。
