Introduction<\/b><\/p>\n

Language and concepts are important. Depending on how they are used across different contexts, meanings shift, which has implications for how people behave and respond. While this topic is arguably relevant across all settings, the following article will examine the importance of concepts and language in the context of road safety; specifically, the term \u201caccident\u201d versus \u201ccollision\u201d or \u201ccrash.\u201d It is important to recognize that road safety is a significant public health matter (Public Health Ontario, 2025), with road traffic incidents ranked as the third highest cause of injury in Canada resulting in significant direct costs, such as direct expenses to the health care system, and indirect societal costs, such as loss of productivity in the workforce (Parachute, 2021). Thus, it is pivotal that efforts to prevent road traffic injuries view these events as preventable and not simply resulting from random and unpredictable conditions.\u00a0<\/span><\/p>\n

Defining Terms<\/b><\/p>\n

The United Nations Office for Disaster Risk Management (UNDRR) defines a road traffic injury <\/span>accident<\/span><\/i> as \u201cinvolving at least one road vehicle in motion on a public road or private road to which the public has right of access, resulting in at least one injured or killed person\u201d (UNDRR, 2025, para. 1). For the UNDRR, this definition includes collisions between road vehicles, road vehicles and pedestrians, road vehicles and animals or fixed obstacles, and road and rail vehicles. Alternatively, in Ontario\u2019s <\/span>Motor Vehicle Collision Report Manual<\/span><\/i> (Government of Ontario, 2011), a <\/span>collision<\/span><\/i> is defined as \u201cthe contact resulting from the motion of a motor vehicle or streetcar and its load, that produces property damage, injury, or death\u201d (p. 2).\u00a0<\/span><\/p>\n

With the UNDRR\u2019s broad use of \u201caccident,\u201d the terms \u201ccollision\u201d and \u201ccrash\u201d are considered accidents. This can be problematic when looking for solutions to prevent future crashes because \u201caccident\u201d implies a lack of fault and that the people involved were not responsible in any way (e.g., not respecting road signage) for causing the collision. In other words, \u201caccident confounds, often erroneously, what happened with the lack of intentionality or legal responsibility of the driver\u201d (Stewart & Lord, 2002, p. 334), sending the message that \u201cthe event is the result of chance and therefore not preventable\u201d (Knechel, 2015, p. 321).\u00a0 However, as emphasized in more recent strategies for road safety, such as the Safe System Approach, collisions are indeed preventable by making changes to the system of roads, as well as driver behaviour.\u00a0<\/span><\/p>\n

Crash vs Accident: An Ongoing Debate<\/b><\/p>\n

The terminology debate between \u201caccident\u201d and \u201ccrash\/collision\u201d is not new (Knechel, 2015). Researchers and health care professionals have used the term <\/span>motor vehicle accident<\/span><\/i> (MVA) since the 1960s (Stewart & Lord, 2002), a term that has likely persisted because of its use in clinical nomenclature (Jablonski, 1998), and its inclusion in reporting and documentation practices among health care professionals (Zuckerman & Estes, 2025). In addition, according to Stewart and Lord (2002), \u201cMVA may have seen continued use because clinicians and researchers have assumed that most vehicular crashes were indeed random events, unintentional, or truly accidental in their origin\u201d (p. 333). However, in recent years, scholars and clinicians (e.g., Knechel, 2015; Stewart & Lord, 2002) have advocated for a shift to the language to <\/span>motor vehicle collisions<\/span><\/i> (MVCs).<\/span><\/p>\n

Advocates for this change in language claim that MVA does not adequately describe crash situations because most vehicular crashes result from preventable actions. In other words, \u201cmost transportation incidents are not accidents. Most incidents were the result of the driver purposely doing something else besides focusing on their driving and the driving environment\u201d (Safety Driven, 2026, para. 3). This debate has been addressed in the context of clinical medicine as well, where it was argued that the term \u201caccident\u201d ought to be replaced with \u201cinjury\u201d (Doege, 1978) because the term accident \u201csuggests it is a random act, attributable to chance, and lacks fault\u201d (Knechel, 2015, p. 322). Significant changes in this realm include the banning of the term \u201caccident\u201d in the <\/span>British Medical Journal<\/span><\/i> (BMJ) in 2001, except for its use in the title of an article (Davis & Pless, 2001).\u00a0<\/span><\/p>\n

In the context of road safety organization such as Parachute, Canada\u2019s national charity dedicated to injury prevention, also advocate for a change in language claiming that \u201chow we talk about collisions and injury on our roadways shapes our attitudes\u201d (Teahen, 2021, p. 2). For example, in 2018 Parachute launched a national awareness campaign <\/span>This Was Not An Accident<\/span><\/i>, aligning with its Vision Zero initiatives. Organizations such as the British Columbia Automobile Association (BCAA) has also shifted their language away from \u2018accident,\u2019 recognizing that injuries are not random: they are predictable and preventable (BCAA, 2019). Further there has also been a shift in the vocabularies of professionals working with victims of vehicular collisions because the language of MVA is potentially problematic for those struggling with trauma or loss resulting from a crash. In other words, \u201cthe use of crash can be more validating and meaningful than accident for crash survivors or persons who are mourning the loss of a friend or family member in a crash\u201d (Stewart & Lord, 2002, p. 334).\u00a0<\/span><\/p>\n

Practical Implications: The Safe System Approach<\/b><\/p>\n

This shift in language is reflected in the concepts and definitions used in the <\/span>Safe System Approach<\/span><\/i>. Thus far, it may seem like the intent is to assign the totality of blame on the drivers of motor vehicles; however, this only part of the story. Changing language to acknowledge that the road traffic event can be prevented is pivotal, but a significant body of research and literature shows that the design of the road transport system also plays a part. This acknowledgment has been most clearly actioned in the Safe System Approach, which recognizes the interdependence of safe road infrastructure, safe vehicles, and safe road users (Canadian Council of Motor Transport Administrators [CCMTA], 2026).\u00a0<\/span><\/p>\n

The Safe System Approach is foundational to <\/span>Vision Zero<\/span><\/i>, which aims to eliminate deaths and serious injuries caused by road traffic collisions (Kristianssen et al., 2018) and views road safety as a social contract between system designers and road users (Belin, 2023). This contract implies that \u201cif road users behave within system limits, system designers guarantee that they will not be killed or permanently injured\u201d (Elvik, 2023, p. 2). This is not an opportunity to blame the design of the roads for <\/span>all<\/span><\/i> injuries and deaths; alternatively, we must look more critically at the road users (and their actions) that contravene this contract. For example, speeding is a significant cause of road traffic injury and death (Elvik, 2005). Thus, lowering vehicle speeds is highly correlated with a reduction in collisions and injury severity (Parachute, 2026). In addition, impaired driving and fatigue are also significant factors causing road traffic collisions, which are the direct result of road users\u2019 decisions (Parachute, 2026). The following excerpt from Safety Driven (2026) captures this issue clearly: \u201cIf you purposely decide to speed because you\u2019re running late, that\u2019s a choice you\u2019ve made. If you crash because of the speeding, that\u2019s no accident. It\u2019s a collision. The crash was a direct result of a decision you made\u201d (para. 5).<\/span><\/p>\n

Conclusion<\/b><\/p>\n

Road traffic crashes and collisions are preventable. While there have been significant shifts in language at the policy and program levels (e.g., Safe System Approach), the use of the term \u201caccident\u201d persists amongst road users to describe a crash or collision. We recognize that the language of \u201caccident\u201d can be therapeutic for folks involved in the crash or collision directly because it deflects blame away from them, which may reduce the psychological stress. However, if we take seriously the goal of improving safety seriously, we must change our language as well and, as road users, reflect on what we can do to prevent tragic crashes and collisions.\u00a0<\/span><\/p>\n
