虚心请教：车前面的大灯什么时候可以用？

[hummingbird166]

昨天晚上从多伦多返回渥太华， 在高速上开看不清路，把大灯打开以后就看的特别清楚，但是不明白为什么有车朝我按喇叭，难道是不应该开大灯吗？

你前面的车按你喇叭？还是后面的车？或者是对面方向的车？

前方150米有同向和反向行驶的车的时候要关掉。

那个大开车最开始在我前面， 他一个劲儿， 在那里闪他的车灯， 我不知道他是不是在暗示我什么，等我超到他的前面以后，他用从后面按喇叭， 我不明白是不是因为开大灯的原因， 再说我也确实不知道什么时候可以用那个大灯：）。

你考试的时候没好好看交通规则：".When you use high-beam headlights, remember to switch to low beams within 150 metres of an oncoming vehicle. Use your low beams when you are less than 60 metres behind another vehicle unless you are passing it. These rules apply to all roads, including divided ones...."

如果是对面来车，没有分隔带，你用大灯晃对方，很可能出车祸。受害的是你自己。

你在他后面开大灯，他无法看到两侧的镜子的东西了。好奇问一下，你开几年车了？

可以开大灯，但不要随意开远光灯（high beam)
How Well Can You See Ahead?
Many users are confused about when to use of low beam and high beam headlights.

Think about this: low beams let you see about 200 feet ahead. It can take about 200 feet to stop when you drive at 30 mph. That is almost half a city block in length. If you cannot see 200 feet ahead, you may not be driving safely at 30 mph. By the time you see an object in your path, it may be too late to stop without hitting it.

Headlights on “upper” or “high” beam let you see about 350-400 feet ahead. 400 feet is your approximately stopping distance when driving at 50-55 mph. That is about the length of a city block.

In other words, high beams let you see twice as far as low beams.

When to Use High Beam Headlights
In any situation when you cannot see well enough ahead, you should start by slowing down. Remember the basic speed law and the two-second rule. When you cannot see well enough, you must increase your following distance which means more seconds. If there are no oncoming vehicles, turn on your high beam headlights.

In general, you should always use high beams outside cities and in rural areas, as long as there are no other vehicles around. Dim your lights when there are oncoming vehicles, or when you are approaching another vehicle from behind.

During poor visibility it is particularly important to use high beams on unfamiliar roads, on dark city streets, in construction areas, or where there may be people or bicyclists along the side of the road. Remember to adjust you speed and not overdrive your headlights.

You must also dim your headlights in all situations when there is a risk of blinding other drivers with your high beams.

Exception from the Rule
Sometimes, however, high beams will not improve your visibility. In fact, it will do the opposite.

This happens in fog, heavy rain, and snow. In these situations, the light from your high beams will reflect back from the fog/rain/snow and cause glare. The glare will make it more difficult to see ahead. To improve visibility, switch to low beams.

Some vehicles have fog lamps that may be used in combination with low beams. Fog lamps will illuminate road edges and pavement markings, making it easier to stay in lane. The should only be used in heavy fog, rain, or snow. Turned them off during normal driving conditions.

国内说开大灯就是远光灯的意思吧。
