Why is tailgating (driving too close behind the vehicle in front) dangerous?
- Correct answerThe vehicle will not have enough distance to stop safely in an emergency.
- The vehicle will exceed the speed limit.
- The braking system is less efficient in the slipstream of the vehicle in front.
- The engine may overheat because of restricted air flow over the vehicle’s engine.
Explanation
If you drive too close to the vehicle in front and it brakes suddenly, you will not have enough time to react. For that reason you should always keep a safe distance from the vehicle in front. One way of calculating a safe distance in dry weather is the two-second rule: allow at least two seconds to elapse between the vehicle in front and your own vehicle passing a fixed point such as a lamp post or sign post.

为什么紧跟（在前车后面开得太近）是危险的？
- 该车辆在紧急情况下没有足够的距离安全停车。
- 车辆将超速。
- 在前车尾流中，制动系统的效率较低。
- 由于车辆发动机的气流受限，发动机可能会过热。
如果你开车离前方车辆太近，而前车突然刹车，你将没有足够的时间反应。因此，你应始终与前车保持安全距离。在干燥天气下计算安全距离的一种方法是两秒规则：确保前车经过固定点（如路灯或标志牌）后至少两秒钟，你的车才经过该点。
