British Columbia has long been at the forefront of implementing stringent measures to combat impaired driving, a leading cause of road accidents and fatalities. 

While legislation and enforcement play a crucial role, technology has become an increasingly powerful tool in the fight against impaired driving.

Today’s article explores the technological devices used in BC, their effectiveness, potential drawbacks, and what drivers need to know when these technologies are involved in their case.

Breathalyzers: The First Line of Defense Against Impaired Driving

Breathalyzers are perhaps law enforcement’s most well-known tool to detect impaired driving.

These portable devices measure the alcohol concentration in a driver’s breath, estimating their blood alcohol concentration (BAC).

In BC, if a driver’s BAC exceeds the legal limit of 0.08%, they can face Immediate Roadside Prohibitions (IRPs), fines, and criminal charges.

However, despite their widespread use, breathalyzers are not without their flaws.

Inaccurate readings can result from improper calibration, environmental conditions, and certain medical conditions (like acid reflux or diabetes).

Ignition Interlock Devices: Ensuring Safe Driving Post-Conviction

For drivers convicted of impaired driving offences in BC, Ignition Interlock Devices (IIDs) often become a mandatory part of their penalty.

An IID is a breathalyzer-like device installed in a vehicle that requires the driver to provide a breath sample before the engine starts.

If the device detects a BAC above the set limit, the vehicle will not start.

IIDs are effective in reducing recidivism among impaired drivers by up to 90%, providing a continuous reminder of the importance of sober driving.

However, they also come with significant costs, including installation fees, monthly maintenance, and removal charges.

While IIDs are generally reliable, they, too, are susceptible to technical issues that can result in false positives or other malfunctions.

Technology & DUI Defences

While technology plays a crucial role in enforcing DUI laws, it also presents opportunities for legal defence.

Challenging the accuracy and reliability of breathalyzer results or the functionality of an IID can be a smart strategy to reduce or dismiss charges.

Drivers should work closely with a DUI lawyer with experience using these technologies to examine any potential flaws in the evidence thoroughly.

Speak to a DUI Lawyer

While these tools have made roads safer, they are not without limitations and potential issues. Drivers facing DUI charges must be aware of how these technologies work and the role they can play in legal defence.
