After a motor vehicle accident in Alberta, drivers face two overlapping legal frameworks at the same time. Alberta’s Traffic Safety Act requires drivers to report the accident to police in certain circumstances. The Canadian Charter of Rights and Freedoms protects the right to silence and the right to counsel in criminal investigations. The relationship between those two frameworks is technical and consequential. Statements made for one purpose may, or may not, be admissible against the driver for another purpose. The line between them is the central legal issue in many criminal driving prosecutions, and getting it wrong can change the outcome of the case.
The criminal defence lawyers at Davidson Gregory have decades of experience defending impaired driving, dangerous driving, criminal negligence, and other Criminal Code driving offences across Alberta.

The Two Sets of Rules That Apply at the Scene
After an accident, two distinct legal regimes apply at the same time. The first is the regulatory regime under Alberta’s Traffic Safety Act, which imposes obligations on drivers involved in accidents, including the obligation to report the accident to police in certain circumstances. The second is the criminal regime under the Criminal Code of Canada, which is engaged when police suspect that an offence has been committed. The Canadian Charter of Rights and Freedoms applies to the criminal regime and protects the rights of the person under investigation, including the right to silence and the right to counsel.
The two regimes can apply to the same driver at the same accident at the same time. The same officer at the scene can be acting as both an accident investigator under the regulatory regime and a criminal investigator under the criminal regime. The driver may not be told which role the officer is in, and may not know whether they are being investigated criminally. The driver’s statements may be relevant to both regimes. Whether the regulatory obligation to report or the constitutional right to silence governs depends on the purpose of the statement and the legal context in which it is made.
The Mandatory Accident Report Under the Traffic Safety Act
Alberta’s Traffic Safety Act requires a driver involved in an accident to provide a report of the accident to a peace officer or to an authorized member of a police service. There is a narrow exemption from the reporting obligation set out in Alberta’s Operator Licensing and Vehicle Control Regulation: a driver is not required to make an accident report if no one was injured or killed in the accident and the apparent cost to repair property damage is below a threshold amount published by the Registrar each year. Outside the exemption, the reporting obligation applies.
Failure to report an accident as required by the Traffic Safety Act is itself a regulatory offence. The reporting obligation is a regulatory tool: it exists to ensure that motor vehicle accidents are documented, investigated for safety purposes, and recorded for insurance and civil liability reasons. The reporting regime is separate from any criminal investigation that may run alongside it, even though both may involve the same officer asking questions of the same driver at the same scene.
The Right to Silence and the Right to Counsel Under the Charter
The Canadian Charter of Rights and Freedoms protects the right to silence in criminal investigations. The right is rooted in the principle against self-incrimination, which the Supreme Court of Canada has repeatedly described as a fundamental tenet of the Canadian legal system. Detained or arrested individuals are entitled to remain silent in the face of police questioning. Silence cannot be used as evidence of guilt at trial.
The Charter also protects the right to retain and instruct counsel without delay on detention or arrest. Once the right to counsel is triggered, the police are required to inform the person of the right and, if the person wishes to exercise it, to suspend questioning until the person has had a reasonable opportunity to consult counsel in private. Statements obtained in violation of the right to counsel can be excluded from evidence at trial under the Charter‘s remedies provisions, sometimes with case-ending effect.
The constitutional rights to silence and to counsel apply when the driver is detained or arrested for a criminal investigation. They do not, on their own, eliminate the regulatory obligation to report the accident under provincial highway traffic legislation. The two regimes coexist.
R v White and Use Immunity for Compelled Accident Reports
The Supreme Court of Canada addressed the intersection of the regulatory reporting obligation and the right to silence in R v White. The Court held that statements made by a driver for the purpose of complying with a provincial accident reporting requirement cannot be used as evidence against the driver in subsequent criminal proceedings. This is a use immunity flowing from the Charter and the principle against self-incrimination.
The rationale of White is that drivers should not be placed in the impossible position of choosing between complying with their regulatory reporting obligation and incriminating themselves in a criminal proceeding. If the regulatory obligation requires the statement, the statement is in a meaningful sense compelled. Compelled statements obtained under penalty cannot then be used to convict the person of a different criminal offence. The use immunity ensures that the regulatory regime does not become a tool for circumventing the criminal right to silence.
The Limits of the Use Immunity
The use immunity in White does not apply to every statement made to police at the scene of an accident. The protected category is limited to statements made for the purpose of complying with the regulatory reporting obligation. Whether a particular statement falls inside or outside the protected category is a fact-specific question that depends on the circumstances of the encounter and the credibility findings made by the trial court. The technical analysis is often the central issue in pre-trial Charter applications in driving cases, and outcomes vary significantly from case to case. An experienced criminal defence lawyer at Davidson Gregory can assess whether a particular statement falls inside or outside the use immunity in a specific file.
The Alberta Position After R v Korduner
For Alberta, the most recent appellate authority on the use immunity for compelled accident reports is R v Korduner, 2025 ABCA 30. The Alberta Court of Appeal held that the bright line drawn in White between a statutorily compelled accident report and a criminal investigation with the driver as suspect does not apply with the same force in the context of a roadside impaired driving investigation.
The Court’s reasoning in Korduner is contextual. In the roadside impaired driving setting, a compelled statement is typically used only to justify the officer’s reasonable suspicion or reasonable grounds to demand a breath sample. The breath sample, once obtained, produces objective scientific evidence of impairment that is independent of the compelled statement. The Court reasoned that the concerns of state misconduct that underlie the White use immunity are attenuated in this specific context, and the use immunity should not necessarily prevent a compelled statement from being used for the limited purpose of grounding a breath demand.
Korduner does not eliminate the use immunity in Alberta. The Alberta Court of Appeal was clear that it was not collapsing the distinction between statutorily compelled and other statements. The use immunity continues to apply in many contexts, including criminal driving prosecutions where the compelled statement may be used to prove an element of the offence rather than to ground an investigative demand. But in roadside impaired driving cases specifically, the Korduner analysis materially constrains the protection that drivers had previously been thought to have under White against having their compelled statements used against them.
The Supreme Court of Canada has granted leave to appeal Korduner, and a decision from the Court is pending as of the date of this article. The Court’s eventual ruling may modify or reaffirm the Alberta Court of Appeal’s analysis. In the meantime, Korduner governs in Alberta, and the analysis is fact-specific. An experienced criminal defence lawyer at Davidson Gregory can assess how Korduner applies to a particular file and follow developments at the Supreme Court.
How Police Investigations of Driving Incidents Typically Unfold
At the scene of an accident, the officer who attends has multiple potential roles. They may be conducting a regulatory accident investigation under provincial highway traffic legislation. They may be conducting a criminal investigation under the Criminal Code. They may be doing both at the same time, transitioning from one to the other as the facts develop and the officer’s suspicions evolve. The driver at the scene is often unaware which role the officer is in. The driver may believe they are simply complying with their regulatory reporting obligation when they are in fact making statements that police will rely on in a subsequent criminal prosecution.
Detention for criminal investigation triggers the Charter rights to silence and to counsel. Determining when detention has been triggered is itself a technical legal question that turns on the specific circumstances of the encounter and is often a central issue in pre-trial Charter litigation.
Why the Distinction Matters for the Defence
The treatment of statements made at the scene of an accident is often the central legal issue in criminal driving prosecutions. Whether a particular statement was a compelled regulatory report (and therefore subject to the use immunity, or to the modified analysis under R v Korduner in roadside impaired driving cases) or an investigative statement (and therefore admissible subject to the Charter and the common-law confessions rule) can determine whether the Crown has sufficient evidence to proceed.
The analysis is fact-specific and turns on a range of factors particular to the encounter, the questioning, and the way the prosecution proposes to use the statement. These are issues that require careful legal analysis by experienced criminal defence counsel. The criminal defence lawyers at Davidson Gregory regularly bring pre-trial Charter applications to challenge the admissibility of statements made at the scene of motor vehicle accidents and to seek Charter remedies where police conduct has fallen short of constitutional standards.
Why the Timing of Legal Advice Matters
For drivers involved in a car accident in Alberta, the timing of legal advice can matter as much as the content of it. Where the circumstances allow it, contacting an experienced criminal defence lawyer, driving offence lawyer, or impaired driving lawyer before providing an accident report can help preserve the right to silence in any criminal investigation that may follow. The post-accident period is fact-specific. There is no general legal advice that applies to every accident, and what makes sense in one file may not make sense in another.
Whether you are still at the scene, recently in receipt of police questioning, or learning that a criminal investigation may follow, the legal landscape is technical. The interaction between the regulatory reporting obligation under the Traffic Safety Act, the right to silence and the right to counsel under the Charter, the use immunity recognized in R v White, and the Alberta-specific framework after R v Korduner is not intuitive. The Supreme Court of Canada’s pending decision in Korduner may further reshape the law in this area. Decisions made at the scene or shortly after can have lasting consequences for any criminal proceeding that follows.
An experienced criminal defence lawyer can assess the specific facts of your case and the timing of the encounter. The lawyer can advise on the status of any investigation, the implications of statements that have already been made or are about to be made, the rights that apply going forward, and the next steps appropriate to the circumstances. Davidson Gregory has decades of experience in this area and can be reached at any time.
