Ignition Interlock Devices: How Can They Let Me Drive?

May 5, 2025

In Canada, a conviction for impaired driving has serious legal and personal consequences—but for many, it does not have to mean the end of driving altogether. Through provincial ignition interlock programs, individuals convicted of alcohol-impaired driving may be able to return to the road under closely monitored conditions. These programs are structured to protect public safety while offering offenders a second chance to drive legally and responsibly.

What Is an Ignition Interlock Device?

Ignition interlock devices (IIDs) are designed to prevent impaired driving by requiring drivers to prove sobriety before and during vehicle operation. These devices are widely used in Canada as a condition for licence reinstatement.

Key features include:

· A breathalyzer that prevents the engine from starting if BAC exceeds 0.02%

· Pre-start breath testing

· Random “rolling retests” during operation

· Audible and visual alarms if a test is failed or missed

· Data logging and reporting to provincial monitoring agencies

An IID is a small, dashboard-mounted breathalyzer that must be installed in any vehicle operated by a program participant. The driver must blow into the device to start the engine and may be prompted for random tests while driving. Any attempts to tamper with or bypass the system are automatically recorded and can result in penalties. Provincial authorities review the device data regularly to monitor compliance.

How Can Interlock Devices Help You Drive Again?

Ignition interlock programs offer a path to early reinstatement of driving privileges for those convicted of alcohol-impaired driving. Participation is conditional on fulfilling certain legal, remedial, and technical requirements.

Steps to regain conditional driving privileges:

· Complete a remedial measures program (e.g., Back on Track in Ontario)

· Sign a lease agreement with a government-approved IID provider

· Have the IID installed in your vehicle

· Follow all program rules and monitoring appointments

Once enrolled and in good standing, the individual’s driver’s licence is reinstated with a condition limiting them to operating only IID-equipped vehicles. This conditional licence is strictly enforced, and violations may result in removal from the program.

Who Is Eligible for Early Reinstatement?

Eligibility depends on factors such as prior offences, timing of a guilty plea, and the nature of the offence. Ontario offers a structured program called the Reduced Suspension with Ignition Interlock Conduct Review Program, with multiple pathways based on offender history.

Eligibility streams include:

· Stream A: First-time offenders who plead guilty within 90 days may reduce their licence suspension to 3 months, followed by 9 months of interlock use

· Stream B: First-time offenders who miss Stream A deadlines may receive a 6-month suspension followed by 12 months of interlock

· Stream D: Second-time offenders may reduce a 3-year suspension to 9 months, followed by 18 months of interlock

Those with prior disqualified driving convictions, drug-impaired offences, or charges involving death or bodily harm are typically ineligible for the program. Prompt action and legal advice are essential for Stream A eligibility.

How Long Do You Need to Use the Interlock Device?

The required duration for interlock use varies depending on the offence and the participant’s criminal or administrative driving history.

Typical minimum periods:

· First Criminal Code offence: 1 year

· Second Criminal Code offence: 3 years

· Third Criminal Code offence: 6 years (after a 10-year suspension)

· Administrative suspension: 6 months

These timeframes can be extended if there are program violations, including failed tests or non-compliance with monitoring requirements. Interlock conditions remain in place until all obligations are fulfilled.

What Are the Costs?

Participants are responsible for the full cost of installing, maintaining, and removing the ignition interlock device. These costs are paid directly to an approved provider. For more information, please visit: Smart Start Canada ALCOLOCK Canada

In addition to these costs, participants must attend regular service appointments every 60 days for data downloads and recalibration. Missed appointments can be treated as violations and may lead to additional penalties or extensions.

What Happens If You Break the Rules?

Program rules are strictly enforced. Violations can lead to program expulsion and reinstatement of the original licence suspension, among other penalties.

Examples of violations:

· Failing to install the IID within 30 days

· Tampering with or removing the device

· Driving a vehicle not equipped with an IID

· Missing a breath test or blowing over 0.02% BAC

· Incurring new driving-related charges

Potential consequences:

· Removal from the program

· Reinstatement of the full suspension period

· Extended interlock duration (by 3 to 6 months)

· Vehicle impoundment for up to 180 days

· Fines or additional charges under the Highway Traffic Act or Criminal Code

Even vehicle owners who allow someone with an interlock condition to drive their car may be penalized. Compliance is critical, and violations can have lasting legal and financial consequences.
