钻车缝，英文为：Lane Splitting。维基百科上关于他的描述为：

【https://en.wikipedia.org/wiki/Lane_splitting】

Lane splitting is riding a bicycle or motorcycle between roadway lanes of vehicles driving in the same direction. More narrowly, it refers to overtaking slow or stopped vehicles by traveling between lanes.[1][2] It is also sometimes called lane sharing, whitelining,[3] filtering, or stripe-riding.[4]

Alternatively, lane splitting has been used to describe moving through traffic that is in motion. It is similar to filtering, or filtering forward, which is used to describe moving through traffic that is stopped.[5][6] When the space used is between two lines of vehicles, this is also known as lane splitting; however, filtering can be accomplished by using space on the outside edge of same-direction traffic as well. There can be significant savings of time by bypassing what otherwise would be obstructions.[7][8]

钻车缝 是自行车或摩托车在相同方向的车流车道中间行驶的行为，旨在车道中间超越缓慢或停止的机动车。有时也可以叫做“车道共享”，“白线通行”，“穿梭通行”或者“条状行驶”。

另外，钻车缝也被用来描述在运动的车流中穿行。这很像用于描述在静止的车流中穿行的“穿梭”或者“前穿”，当被使用的空间是位于两行车之间的时候，这就是钻车缝；当然，“穿梭”也可以利用同向车流的外侧空间完成。这样可以大大节省绕开这些障碍的时间。

全美摩托车协会（AMA）在他的主页里就有关于钻车缝的立场声明：

Lane Splitting

The American Motorcyclist Association places significant emphasis on motorcyclei operator and passenger safety. On every type of public roadway, motorcyclists encounter challenges from other roadway users and are constantly vigilant to unsafe conditions around them.

全美摩托车协会致力于摩托车驾驶者和乘坐者的安全问题。 在任何一类的公共道路上，摩托车手都遭受到来自于其他道路使用者的挑战并要不断地提防在他们周围不安全的因素。

Perhaps one of the most dangerous situations for any on-highway motorcyclist is being caught in congested traffic, where stop-and-go vehicles, distracted and inattentive vehicle operators, and environmental conditions pose an increased risk of physical contact with another vehicle or hazard. Even minor contact under such conditions can be disastrous for motorcyclists.

也许对于任何在高速公路上的摩托车手来说最危险的情况就是走走停停的拥堵路段，不专心和开小差的汽车驾驶员以及环境因素使得摩托车与其他机动车产生直接碰擦的风险大大增加。即使是轻微的碰擦也会导致摩托车手严重的伤害。

The Hurt Report1, the most comprehensive motorcycle crash causation study to date, noted that, “Moderate or heavy traffic was the situation at 59.2 percent of the accidents [studied].” Reducing a motorcyclist’s exposure to vehicles that are frequently accelerating and decelerating on congested roadways can be one way to reduce rear-end collisions for those most vulnerable in traffic.

Hurt报告1，日前最权威的摩托车事故原因报告，写道：“研究表明：中度或重度交通阻塞是导致59.2%事故的原因”。减少摩托车手处于拥堵路段中频繁加速减速的情况，是减少导致伤害的追尾事故的方法之一。

In many countries (excluding the United States), lane splittingii and filteringiii are normal practices for motorcyclists. Particularly in the highly urbanized areas of Europe and Asia, motorcycle and scooter operators are expected to pass between conventional vehicles and filter (advance) to the front of the group.

在很多国家（不包括美国），钻车缝和穿行对摩托车手是一种很常见的现象。 尤其在高度城镇化的欧洲和亚洲地区，摩托车和踏板车骑手被鼓励在车流中穿行到队列的最前面。

Recent events in the U.S. have renewed motorcyclists’ interest in lane splitting. Therefore, the AMA has prepared this position statement to aid in understanding this issue and assist motorcyclists in deciding whether to support efforts to permit lane splitting in their state.

最近在美国发生的一些事件提升了摩托车手对于钻车缝的关注度。所以，全美摩托车协会准备了这份立场声明来帮助（公众）了解这个问题并帮助摩托车手决定是否支持在他们所在的州允许钻车缝（合法化）。

The University of California at Berkeley published a report in May 2015 that concludes that motorcyclists who split lanes in heavy traffic are significantly less likely to be struck from behind by other motorists, are less likely to suffer head or torso injuries, and are less likely to sustain fatal injuries in a crash2.

在伯克利的加州大学于2015年5月发布了一项报告，论述了在严重拥堵情况下钻车缝的摩托车手可以大大减少被后车追尾，导致头部和躯干受伤，和永久性伤害的危险。

One of the recommendations in the National Agenda for Motorcycle Safety (NAMS)3 is: “Study the safety implications of lane splitting.” In support of this recommendation, the report states:

在摩托车安全国家议案（NAMS）里有一条建议：“研究关于钻车缝的安全性意义”。为支持这项建议，报告中写道：

“A motorcycle’s narrow width can allow it to pass between lanes of stopped or slow-moving cars on roadways where the lanes are wide enough to offer an adequate gap. This option can provide an escape route for motorcyclists who would otherwise be trapped or struck from behind. There is evidence (Hurt, 1981) that traveling between lanes of stopped or slow-moving cars (i.e., lane splitting) on multiple-lane roads (such as interstate highways) slightly reduces crash frequency compared with staying within the lane and moving with other traffic.

“一辆摩托车”狭小的宽度，足以使其在可以提供充足间距的宽阔路面上从静止或慢速行驶汽车中间通过。这将提供给摩托车驾驶员一个摆脱从后部被撞击或阻碍的选项。在Hurt 1981报告中有证据表明在多车道道路（比如州际公路）上，于静止或慢速行驶汽车车道间穿行，与等在车道内与车流共用行进相比，一定程度上可以减少了事故发生的概率。

“Although lane splitting is allowed in just a few areas of the United States, notably California, it appears to be worthy of further study because it offers a means of reducing congestion in addition to possible safety benefits. It is widely used in many other countries.”

“尽管钻车缝只在美国少数几个区域被允许，特别是加州，仍然有必要继续进行研究因为他不仅对于可能的安全性有好处，同时也可以减少拥堵。这已经被广泛应用于很多其他国家。

In a statement issued by the Motorcycle Industry Council in 2011 and revised in 20144, the trade group states: “In full consideration of the risks and benefits of lane splitting, the Motorcycle Industry Council supports state laws that allow lane splitting under reasonable restrictions.”

在一项由摩托车产业协会于2011制订，2014年修订的纪要中，贸易团体叙述道：全面评估了钻车缝的风险和益处之后，摩托车产业协会支持在合理限定条件下的钻车缝相关立法”

For decades, California has been the only state to permit lane splitting. While not specifically permitted or prohibited in the California Vehicle Code, lane splitting authority comes from the California Highway Patrol. In early 2013, the CHP published lane splitting guidelines5 for the first time. While the guidelines do not carry the force of law, they provide clear indicators under which a motorcyclist might be cited for unsafe or imprudent behavior.

过去的几十年，加州是唯一一个允许钻车缝的州。在加州机动车行为准则中，并没有明确允许或禁止（钻车缝），它的权威来自于加州高速公路巡警。在2013年初，CHP第一次出版了钻车缝指导意见。虽然指导意见不具有法律权威性，他们还是提供了一个清晰的关于界定摩托车手是否是不安全和鲁莽（驾驶）的行为准则。

Legislatively, there has been state-level activity on lane splitting, although to date no bill has been enacted.

Passing legislation to permit lane splitting may be the easiest part of the process. Significant effort would subsequently be required to educate the law enforcement community, officials and administrators within state departments of transportation and public safety, prosecutors, the judiciary and the general motoring public on the benefits to those groups and motorcyclists to make lane splitting safe for everyone. Using public service announcements and campaigns, traditional broadcast and print media, social media, and other forms of information sharing could assist in highlighting the safety, congestion reduction, and other benefits of lane splitting.

从立法的角度来说，关于钻车缝，曾经有州一级的行动，时至今日也没有发过任何一张罚单。通过立法来确认钻车缝也许是整个流程中最容易的一环。后续还需用大量的精力去指导州交通和公共安全部门的执法部门团体， 官员以及管理者，检查官，司法部门和普通的驾驶者，关于对这些团体带来的好处以及摩托车手如何钻车缝对公众来说才是安全的。利用公共服务声明和活动，传统传播广播和平面媒体，社交媒体以及其他信息共享的方式来宣传对于(它）提高安全性和减少拥堵以及其他方面的种种好处。

Taking into consideration that the vast majority of the motoring public does not ride motorcycles, we are certain non-motorcyclists do not understand the risks and the benefits of lane splitting to the riding community. Motorists in California being the exception, we believe it would take many years of experience and substantial and ongoing public information campaigns to educate non-motorcyclists to accept motorcyclists passing them between lanes of traffic.

考虑到主流的驾驶公众并不驾驶摩托车，我们肯定非摩托车驾驶员无法理解钻车缝对于骑行社团的风险和益处。 加州的摩托车手作为一个例外，我们相信这将是一个经历数年并且持久不断的公共信息公关来教导非摩托车手来接受在车流中间穿行的方式。

The AMA endorses rider responsibility and actions that make roadways safer for motorcyclists. While research and evidence suggest that lane splitting may reduce a motorcyclist’s risk exposure somewhat, we are cautious to issue a blanket endorsement supporting the practice. In particular, experience has taught us that the legislative process and the implementation of new laws are fraught with uncertainty. A straightforward lane splitting bill may easily be amended with provisions that the AMA and the motorcycling community would find unacceptable. Provisions such as mandatory helmet use in an adult-choice state or mandatory minimum medical insurance coverage provisions would quickly poison an otherwise well-intentioned effort.

全美摩托车协会支持骑士们以责任和行动来捍卫摩托车手们在道路上的安全。尤其是相关研究和证据都认同钻车缝可以减少摩托车手的显著风险，但是我们依然非常小心起草一份支持这种行为的倡议书，经验告诉我们立法过程和新法律的执行充满了不确定性，一些在全美摩托车协会和摩托社团里无法接受的行为将会招致直接的钻车缝条例修订，比如在某些成人必须佩戴头盔的州不佩戴头盔，或者没有必须的最基本医疗保险这样的行为将使我们各种的努力付之东流。

Motorcyclists who oppose lane splitting should remember that it is optional in California. Permitting lane splitting is not the same as requiring it, so those opposed to the practice should consider the desires of other motorcyclists who believe they would benefit from it. Lane splitting is an issue of choice.

反对钻车缝的摩托车手应该记得在加州这是一项可选的行为。允许钻车缝不代表你必须这么做，所以那些反对者请考虑其他坚信这样可以带来好处的骑手们的期待，钻车缝只是一种选择。

Even with the best intentions and organization, inappropriate behaviorXSS by motorcyclists can quickly garner a large negative response from the motoring public. With the easy availability of video systems and the Internet, a few postings of public roadway stunting, such as speeding past motorists stuck in traffic, could sour a legitimate campaign to approve lane splitting in a state. While the AMA has long advocated responsible riding practices and does not condone any behaviorXSS that violates the rules of the road, we caution that the future of lane splitting in any state could be derailed by the actions of a few irresponsible motorcyclists. Advocates of lane splitting should be prepared to counter any negative responses they receive from legislators and those responsible for implementing lane splitting laws. 

尽管有着很好的目的和组织，摩托车手们的不当行为还是可以很快地招致来自于驾驶公众大量负面的反馈。尤其是当下普及的录影系统和互联网，一小部分关于公路上玩车的视讯，比如交通阻塞时候超速的摩托驾驶。都会招致在批准钻车缝的州立法条文时面临着不愉快的经历。全美摩托车协会始终倡导负责任的驾驶方式并无法宽恕任何违反道路法则的行为。我们需要警惕在任何一个州 钻车缝 的未来都有可能被一小部分不负责任的摩托车手给毁掉。钻车缝的倡导者需要准备好反击任何接受到来自于立法者和执法者的负面反应。

Given the ongoing success of lane splitting in California and the recent enthusiasm for lane splitting and/or filtering in other states, the AMA endorses these practices and will assist groups and individuals working to bring legal lane splitting and/or filtering to their states.

对于在加州钻车缝（立法）的成功和近期致力于在其他州推动钻车缝和穿梭(合法化)，全美摩托车协会支持这样的行为并将协助那些致力于此的个人和团体。。。

正常情况下，有红绿灯的十字路口，停车线前有摩托车专用前置区……不钻车缝成吗？另外在拥挤的路段，同一车道摩托车尽量两车并行，减少拥堵也是合理的！有些东西不能死搬教条！

       上路行驶应以最大限度的安全为原则！比如说：法律规定在同向多车道的公路上，大货车和摩托车在最右侧车道通行！骑车的人都知道，最右侧是最危险的车道，原因我就不说了；但这样划分的依据实际还是认为摩托车低速，跟不上轿车；但在普通多车道的公路上，最高限速也就60或80，125以上的摩托应该都没得问题吧！所以还是应该根据自己的实际速度选择车道较合适，安全！

法是死的，也是需要不断完善的！不合情不合理的法律要有挑战它的勇气！才能争取到应有的权利！
