Dangerous Driving Charges in Alberta: What You're Actually Facing

Dangerous driving sits at the boundary between provincial traffic regulation and federal criminal law, and the line is not always drawn where it should be. A collision that looks, to the attending officer, like more than a regulatory matter — speed, an intersection, an injury — is frequently elevated to a charge under section 320.13 of the Criminal Code. Once charged, the consequences are severe. A conviction is a criminal record. A conviction involving bodily harm or death exposes the accused to penitentiary-range sentences. The Crown is not required to prove an intent to harm — only that the driving constituted a marked departure from the standard of care a reasonable person would have observed in the same circumstances.

This page explains how dangerous driving offences are framed under the modernized impaired-and-dangerous driving provisions enacted by Bill C-46 in December 2018, what the Crown must actually prove under the framework set by the Supreme Court of Canada in R v Beatty, 2008 SCC 5, R v Roy, 2012 SCC 26, and R v Chung, 2020 SCC 8, the interaction between Alberta's Traffic Safety Act reporting obligations and the right to silence, the discretionary federal driving prohibition under s. 320.24 and the parallel automatic provincial disqualification under the Traffic Safety Act (with its consecutive-stacking rule), where these files can be reduced to careless driving, and the procedural and Charter defences that engage in serious collision investigations. KJR Law represents people facing dangerous driving charges across Calgary and Southern Alberta.

What You Must Say at the Scene — and the Privilege That Protects You When You Do

The relationship between a driver's obligations at the scene of a collision and the right to silence is more nuanced than most advice suggests. Alberta law imposes real reporting duties on drivers, and refusing to comply with them is its own offence. The same law, however, surrounds those compelled statements with one of the strongest privileges in Canadian provincial legislation — and the Canadian Charter of Rights and Freedoms overlays a constitutional protection on top.

What Alberta's Traffic Safety Act requires. Sections 69 and 71 of the Traffic Safety Act impose four obligations on the driver of a motor vehicle involved in an accident:

• remain at the scene of the accident;
• render reasonable assistance to any injured person;
• on request, give your name, address, driver's licence number, vehicle registration, and proof of insurance to any person involved or to the police; and
• file an accident report with police where the threshold for reporting is met — generally, where there is injury, death, or property damage above the prescribed amount (s. 71).

These are not optional. Failure to remain, failure to render assistance, and failure to file the required accident report are each independent offences under the Traffic Safety Act. The federal offence of failing to stop at the scene under s. 320.16 of the Criminal Code sits alongside the provincial duty.

The statutory privilege under TSA s. 11. The trade-off built into Alberta's reporting framework is significant. Under s. 11 of the Traffic Safety Act, an accident report made under s. 70 (a peace officer's report) or s. 71 (a driver's report) is inadmissible as evidence in any legal proceeding arising out of the accident, except to prove three narrow things: compliance with the reporting obligation itself, the falsity of the report in a prosecution for making a false statement, and the identity of the drivers involved. The provincial legislature recognized, in creating the duty to report, that compelling a driver to make admissions against their own interest in fulfillment of a public-safety statute could not stand without a corresponding privilege.

The Charter use immunity from R v White. Independent of the provincial privilege, the Supreme Court of Canada held in R v White, [1999] 2 SCR 417 that statements compelled by a statutory duty to report an accident are protected by the principle against self-incrimination under s. 7 of the Charter. Where a driver makes a statement under the honest and reasonable belief that they are required to do so by the duty to report, that statement is "compelled" within the meaning of s. 7 and may not be used as direct evidence against the driver in a subsequent criminal proceeding. The protection is "use" immunity, not "derivative use" immunity — the statement itself is inadmissible, but evidence found through investigative leads contained in the statement may still be admissible, subject to the Crown discharging its burden to show the evidence would have been discovered independently. The precise reach of that immunity is currently before the Supreme Court of Canada in R v Korduner (SCC File No. 41737) — including whether it extends to derivative use and to a breath demand founded on a compelled accident statement — so its boundaries on those points are, for now, unsettled.

The line between compelled and voluntary. The protection in s. 11 of the Traffic Safety Act and the use immunity under White apply to statements made in fulfillment of the duty to report. They do not protect everything a driver says at the scene or afterward. A statement volunteered at the roadside that goes beyond what the duty to report requires — about fault, about what the driver perceived, about what the driver was thinking — sits outside the privilege and the immunity. The same is true of statements given later to investigators at a police detachment, where the duty to report is no longer the operative compulsion. Where the line falls in a particular file is sometimes contested ground.

The practical advice. Comply with the obligations under s. 69 and s. 71 of the Traffic Safety Act. Identify yourself. Provide the documents. File the required report. Beyond that, exercise the right to remain silent under s. 7 of the Charter and the right to retain and instruct counsel without delay under s. 10(b). Statements compelled by the duty to report carry meaningful protection. Statements that go beyond what the duty requires do not. The cleanest path is to fulfill the obligation, ask for counsel before going further, and let the privilege do the work it was designed to do.

The Three Levels of Dangerous Driving

Section 320.13 of the Criminal Code creates three offences, differentiated by the consequences of the dangerous operation. The conduct required for each — the manner of operation that constitutes the offence — is the same.

• Dangerous operation — s. 320.13(1). Operation of a motor vehicle in a manner that, having regard to all the circumstances, is dangerous to the public. Hybrid offence. Maximum 10 years on indictment. No mandatory minimum.
• Dangerous operation causing bodily harm — s. 320.13(2). The same conduct, where bodily harm to another person results. Bodily harm means hurt or injury that interferes with health or comfort and is more than merely transient or trifling. Hybrid. Maximum 14 years on indictment, and a mandatory minimum punishment on every conviction — a $1,000 fine on a first offence, 30 days' imprisonment on a second, and 120 days on a subsequent offence (s. 320.2).
• Dangerous operation causing death — s. 320.13(3). The same conduct, where death results. Indictable. Maximum life imprisonment, carrying the same mandatory minimum punishment as the bodily-harm offence — a $1,000 fine on a first offence, rising to 30 and then 120 days on subsequent offences (s. 320.21).

What the mandatory minimum means for sentencing. Because a minimum punishment is prescribed for the bodily-harm and death offences, two dispositions that are otherwise common in driving matters are unavailable on a conviction for either. An absolute or conditional discharge cannot be granted, because a discharge under s. 730 is available only where no minimum punishment is fixed by law. A suspended sentence is unavailable for the same reason under s. 731. A conditional sentence order — a custodial sentence served in the community — can be available on a first offence, because the minimum there is a fine rather than a term of imprisonment and so does not engage the bar in s. 742.1; the former categorical bar on conditional sentences for offences carrying a 14-year or life maximum was repealed by Bill C-5 (S.C. 2022, c. 15). A conditional sentence remains subject to the court's assessment of community safety and to the requirement that the fit sentence not exceed two years less a day. On a second or subsequent offence, where the prescribed minimum becomes a term of imprisonment, the conditional-sentence route is closed.

Charges relating to incidents before December 18, 2018 fall under the predecessor provisions (former ss. 249 and 249.1) rather than the modernized regime under s. 320.13. The substantive elements are largely parallel but the procedural framework differs in some respects.

What the Crown Must Prove: The "Marked Departure" Standard

Dangerous driving is an objective mens rea offence. The Crown must prove two things beyond a reasonable doubt.

Actus reus. The accused operated a motor vehicle in a manner that, having regard to all the circumstances, was dangerous to the public.

Mens rea. The manner of operation constituted a marked departure from the standard of care that a reasonable person would have observed in the accused's circumstances. The Supreme Court of Canada set out this framework in R v Beatty, 2008 SCC 5, refined it in R v Roy, 2012 SCC 26, and most recently applied it in R v Chung, 2020 SCC 8. The standard is "marked" — meaningful, significant — not merely "noticeable" or "below average." Momentary inattention, ordinary errors of judgment, and conduct that is dangerous in retrospect but reasonable in the moment do not amount to a marked departure.

The "all the circumstances" framework directs the court to consider the entire context: road conditions, weather, traffic density, time of day, visibility, the design of the road, the configuration of the intersection, the speed of other vehicles, and the conduct of other road users. A manoeuvre that would be a marked departure on a busy urban arterial in heavy rain may not be a marked departure on a clear, empty rural highway. Roy is explicit on this point: the question is not "was the driving objectively dangerous?" but "did the manner of driving represent a marked departure from the standard a reasonable driver would have observed in those specific circumstances?"

Dangerous Driving Causing Death: Causation and the Aftermath

In a dangerous driving causing death prosecution, the Crown must additionally prove that the dangerous operation caused the death. The test is whether the dangerous operation was a significant contributing cause. Where the deceased's own conduct, the actions of another road user, or an intervening event provided the operative cause of death, the causation analysis becomes the dispositive question.

Sentencing in fatality files engages the full sentencing principles in s. 718 of the Criminal Code, with denunciation and deterrence weighted heavily. The available range runs from significant custodial sentences in cases involving substantial fault down to, at the lowest end of the marked-departure spectrum, a conditional sentence served in the community. As noted above, the mandatory minimum attached to the offence means an absolute or conditional discharge and a suspended sentence are not available; the realistic non-custodial option is a conditional sentence on a first offence, and even that is uncommon in fatality cases, where a fit sentence frequently exceeds the two-years-less-a-day ceiling that a conditional sentence cannot cross. Each file's placement within the range is determined by the conduct, the circumstances of the offender, any prior driving record, and the strength of any mitigating factors.

Dangerous Driving vs. Careless Driving Under Alberta's Traffic Safety Act

Alberta's Traffic Safety Act contains a separate, provincial offence of careless driving under s. 115(2)(b). Careless driving is not a criminal offence. It produces a fine, demerit points on a driver's record, and at the higher end can produce a licence suspension — but no criminal record, no criminal sentence, and no Crown prosecution.

The substantive test for careless driving is whether the accused drove "without due care and attention or without reasonable consideration for persons using the highway." That standard sits below the marked-departure standard for criminal dangerous driving. The same conduct can, in principle, support either charge — and Crown discretion is often exercised, with appropriate advocacy, to resolve a dangerous driving Information by reduction to careless driving.

A reduction to careless driving is one of the most consequential resolution paths in a dangerous driving file. It eliminates the criminal record, the federal driving prohibition, the immigration consequences, and the United States travel inadmissibility that follow a federal conviction. It is not available in every file — fatalities and serious bodily harm cases are rarely amenable — but in genuine borderline cases it represents a substantial favourable outcome.

The Defences That Actually Work

Most dangerous driving prosecutions turn on technical evidence and the application of the marked-departure standard to the specific facts. The arguments that succeed:

The marked-departure threshold. Was the driving truly a marked departure from the standard a reasonable driver would have observed in those circumstances — or was it ordinary negligence, momentary inattention, or a misjudgement that reads worse in hindsight than it was in the moment? Roy sets a high bar. Many files do not clear it.

Collision reconstruction. Crown reconstruction reports are interpretations of physical evidence, not facts. Speed estimates from skid marks, crush deformation, and impact angles each carry their own error ranges. A defence-retained reconstruction engineer can produce a materially different speed estimate or a different account of the sequence of events.

Causation. In bodily harm and fatality cases, did the alleged dangerous operation actually cause the injury or death? Where the deceased was speeding, ran a red light, was not wearing a seatbelt, was intoxicated, or where another driver bore meaningful responsibility for the collision, the causation analysis becomes the central issue.

Mechanical failure and road conditions. A loss of control caused by mechanical failure not reasonably foreseeable by the driver, or by an unexpected road defect, can take a file outside the marked-departure framework entirely. Maintenance records, inspection reports, and the physical condition of the road at the time of the collision matter.

Accident report use immunity and TSA s. 11 privilege. Where the Crown's case relies on a statement the accused made in fulfillment of the duty to report under s. 71 of the Traffic Safety Act, the statement is inadmissible at the criminal trial — both under s. 11 of the Traffic Safety Act and under the Charter use immunity recognized in R v White, [1999] 2 SCR 417. The defence work involves identifying which of the accused's statements were compelled by the duty to report and which were voluntary, and pressing the inadmissibility argument as to the compelled portion. Where the Crown's case rests substantially on a compelled statement, exclusion can reshape the prosecution.

Other Charter defences. Voluntary statements taken without proper advice of rights, breath or drug samples taken in circumstances that may not have met the lawful demand framework under s. 320.27 or s. 320.28, warrantless seizures of vehicle data through Event Data Recorder downloads, and unlawful detentions all engage ss. 8, 9, 10(a), and 10(b) of the Charter. Excluded statements and excluded vehicle data can transform the trajectory of a file.

Disclosure issues. Modern dangerous driving prosecutions involve voluminous digital disclosure — body-worn camera footage, dashcam recordings, traffic camera footage, 911 audio, EDR downloads, scene photographs, reconstruction software files. Delays in producing disclosure engage the framework in R v Jordan, 2016 SCC 27.

Federal Driving Prohibition Under Section 320.24

A conviction under section 320.13 of the Criminal Code triggers a discretionary federal driving prohibition under section 320.24(4). The sentencing court "may" make a prohibition order. There is no minimum prohibition period prescribed by the Criminal Code for these offences. The mandatory prohibition framework under s. 320.24(1) — with its one-, two-, and three-year minimums for first, second, and subsequent offences — applies only to impaired operation under s. 320.14(1) and refusal under s. 320.15(1). It does not apply to dangerous operation, failure to stop, flight from police, or any of the other offences captured by s. 320.24(4).

The maximum prohibition period under s. 320.24(5) is calibrated to the maximum prison sentence available for the offence of conviction:

• Dangerous operation simpliciter prosecuted on indictment — maximum 10 years prohibition, plus the entire period to which the offender is sentenced to imprisonment.
• Dangerous operation simpliciter prosecuted summarily — maximum 3 years.
• Dangerous operation causing bodily harm on indictment — maximum 10 years.
• Dangerous operation causing bodily harm summarily — maximum 3 years.
• Dangerous operation causing death — any duration that the court considers appropriate, plus the entire period of imprisonment.

Because the federal prohibition is discretionary, defence sentencing submissions can engage that discretion — on whether a prohibition is necessary in the circumstances at all, on its length, and on its relationship to any concurrent provincial disqualification. That advocacy space is one of the meaningful values of careful sentencing work in a dangerous driving file.

The Criminal Code contains its own consecutive-prohibition mechanism, distinct from the provincial rule discussed below. Under s. 320.24(9), where the offender was already subject to a federal driving prohibition at the time the new offence was committed, the sentencing court may order the new prohibition to run consecutively to the existing one. Unlike the provincial scheme, this federal stacking is discretionary, not automatic, and it applies only as between federal prohibition orders for the same type of conveyance.

The federal discretion is, however, undercut by the provincial reality that follows. The second consequence — the automatic provincial disqualification under Alberta's Traffic Safety Act, which operates by force of statute rather than by court order — is set out below.

The Parallel Provincial Disqualification Under the Traffic Safety Act — and the Consecutive Stacking Rule

Alberta's Traffic Safety Act imposes its own automatic disqualification, running alongside any federal prohibition imposed, on every conviction under s. 320.13 and a series of related conveyance offences. The provincial disqualification is automatic. It does not require a separate court order. It does not turn on submissions at sentencing. It takes effect on the day of the finding of guilt.

Section 87(1) — one-year automatic provincial disqualification for s. 320.13(1) dangerous operation. Section 87(1) of the Traffic Safety Act provides that a person found guilty anywhere in Canada under s. 320.13(1) (dangerous operation), s. 320.16(1) (failure to stop after accident), or s. 320.17 (flight from peace officer) of the Criminal Code is, on being found guilty, automatically disqualified from driving a motor vehicle in Alberta for one year from the day of the finding of guilt. For a conviction under s. 320.13(1) — dangerous operation without bodily harm or death — the automatic provincial disqualification is one year.

Section 87(2) — five years for dangerous operation causing bodily harm or death. Where the conviction is under s. 320.13(2) (dangerous operation causing bodily harm) or s. 320.13(3) (dangerous operation causing death), s. 87(2) of the Traffic Safety Act extends the automatic disqualification to five years. The same five-year disqualification applies to convictions under s. 320.14(2) or (3), s. 320.15(2) or (3), and s. 320.16(2) or (3).

Section 87(3) — five years for criminal negligence and motor-vehicle manslaughter. A conviction under s. 220 (criminal negligence causing death), s. 221 (criminal negligence causing bodily harm), or s. 236 (manslaughter) of the Criminal Code, where the offence was committed by means of a motor vehicle, triggers a five-year automatic provincial disqualification under s. 87(3). These charges are companion charges in some serious dangerous driving files and carry the same five-year provincial consequence as the s. 320.13(2)/(3) variants.

Section 98 — disqualifications run consecutively, not concurrently. This is the feature of the Alberta scheme that surprises most accused persons. Section 98(1) of the Traffic Safety Act provides that where a person is already under a disqualification, and during that period becomes subject to a new disqualification — either through a fresh provincial disqualification or through a federal driving prohibition under s. 320.24 of the Criminal Code — the new disqualification runs consecutively to any previous disqualification that is still in effect or waiting to go into effect. Section 98(2) extends the same consecutive rule to other sources of TSA disqualification.

The practical consequence: a person already serving a disqualification from an Immediate Roadside Sanction, from an earlier impaired-driving conviction, or from any prior conveyance-offence conviction who is then convicted of a new dangerous driving offence does not have the new disqualification absorb into the existing one. The new disqualification stacks on top, starting only after the existing period has expired. The two periods of disqualification add together rather than overlap. A driver who was, for example, six months into a one-year IRS or post-conviction disqualification at the time of a new s. 320.13 finding of guilt is looking at a total off-road period that is longer than either disqualification standing alone would have produced.

How the federal and provincial schemes interact in practice. A dangerous driving conviction typically produces three intersecting driving consequences: any federal driving prohibition the sentencing court chooses to impose under s. 320.24(4) of the Criminal Code; the automatic provincial disqualification under s. 87 of the Traffic Safety Act (one year for s. 320.13(1), five years for s. 320.13(2) or (3)); and, where any prior disqualification was still active at the time of the new finding of guilt, the consecutive-stacking rule under s. 98 of the Traffic Safety Act. For a person without any active prior disqualification, the federal and provincial periods generally run alongside each other from the date of conviction. For a person with an active prior disqualification, the periods stack. Counsel needs to map all of this out from the first conversation — the total off-road period a client is actually facing is often considerably longer than the federal prohibition figure on its own suggests.

Other Consequences — Insurance, Employment, and Travel

Beyond the licensing track, a dangerous driving conviction produces a series of practical consequences that often have longer real-world impact than the custodial sentence itself:

• Insurance. A dangerous driving conviction frequently moves the driver from the standard insurance market into the high-risk facility, with premium increases of 200 to 400 percent for three to five years. In serious files, the practical loss of standard-market coverage and a forced shift to the Facility Association at considerable annual cost is typical.
• Employment. Drivers in regulated commercial categories — Class 1, 2, 3, 4 — face loss of livelihood. Many employers in trades, transportation, and professional driving require a clean criminal record.
• United States travel. A dangerous driving conviction — particularly one involving bodily harm or death — typically renders a person inadmissible to the United States. A US entry waiver is the only remedy and must be applied for and renewed.
• Immigration consequences. For non-citizens, a dangerous driving conviction triggers an inadmissibility analysis under the Immigration and Refugee Protection Act. Permanent residents may face removal regardless of length of residence in Canada.

Related Offences That Frequently Travel Together

An Information laying dangerous driving charges rarely contains only the s. 320.13 count. Companion charges in modern collision investigations:

• Failure to stop at the scene of an accident — s. 320.16. Where the driver is alleged to have left the scene. Significantly aggravated where bodily harm or death is alleged.
• Criminal negligence in the operation of a vehicle — ss. 219–220 of the Criminal Code. A more serious charge than dangerous driving, requiring "wanton or reckless disregard" rather than a marked departure. Triggers a five-year automatic provincial disqualification under TSA s. 87(3). Notably, the Supreme Court of Canada held in R v Wolfe, 2024 SCC 34 that s. 320.24(4) does not authorize a federal driving prohibition for criminal negligence offences under s. 220 or s. 221, because those provisions are not specified in s. 320.24(4) — the federal prohibition is therefore unavailable on a criminal negligence conviction even where the offence was committed by means of a motor vehicle, though the provincial disqualification under TSA s. 87(3) still applies.
• Impaired operation — s. 320.14. Frequently charged in parallel where the Crown alleges alcohol or drug impairment contributed.
• Flight from a peace officer — s. 320.17. Where the dangerous driving is alleged to have occurred in the course of fleeing police.

Dangerous driving files reward early engagement. The investigation phase — reconstruction work, witness interviews, EDR downloads, body-worn camera review — moves forward whether the accused has counsel or not. Defence-side investigation conducted in parallel, while the scene evidence is fresh and witnesses are still available, can materially shape how a file resolves. The initial consultation is at no charge.
