The search for common and serious single causes of road crashes naturally leads to a concentration on the road user. This is supported by a legal framework in the search for the main cause and the suspect for this cause.

In prevention, we have for decades been more inclined to look for systematic improvements of all elements of the road transport system, and we direct the recommendations for actions towards system designers, organizations, products and services.

In this paper the discussion about causation and prevention is broadened in the light of Vision Zero and its approach to prevention of serious and fatal injuries. We also discuss the Swedish judicial system and why the prevention approach has not been legislated or even generally accepted. Occupational health and safety legislation and road rules are compared, as well as how sustainability practices and reporting are tools to apply prevention where organizations have a natural sphere of influence that could mitigate deaths and serious injuries within value chains.

It is recommended that we stop using the term causation as it is only directing actions in one direction. There is a risk that the focus on causation, in particular single causes, will deviate actions away from robust prevention countermeasures such as increased seat belt use, relevant speed limits, and well functioning roundabouts and median barriers. Furthermore, there is also a risk that important preventative actions from organizations are overlooked.

寻找道路交通事故的常见且严重的单一原因自然会导致对道路使用者的关注。在寻找主要原因和该原因的嫌疑人方面，这一点得到了法律框架的支持。

在预防方面，几十年来我们 更倾向于寻求对道路运输系统所有要素进行系统性改进，并将行动建议针对系统设计者、组织、产品和服务。

本文根据“零愿景”及其预防严重和致命伤害的方法，扩大了关于因果关系和预防的讨论。我们还讨论了瑞典的司法系统以及为什么预防方法尚未立法甚至没有被普遍接受。比较了职业健康和安全立法以及道路规则，以及可持续性实践和报告如何成为在组织具有自然影响力的情况下应用预防的工具，可以减少价值链中的死亡和严重伤害。

建议我们停止使用“因果关系”一词，因为它仅指导一个方向的行动。存在这样的风险：对因果关系的关注，特别是对单一原因的关注，将使行动偏离强有力的预防对策，例如增加安全带的使用、相关的速度限制以及运转良好的环岛和中央隔离带。此外，还存在组织的重要预防措施被忽视的风险。
