If you have an ignition interlock in Ontario, you’re probably already accustomed to bringing your vehicle in for a monitoring appointment at regular intervals. You probably know that data from your device will be downloaded, but there’s a lot more to what happens during that short appointment. Here’s what the technician does during your standard ignition interlock monitoring visit:
Downloads Events Log
The Events Log from your interlock use and driving is downloaded and sent to the authorities. The log records a large amount of data, all of it time-stamped and dated. This includes:
- Engine starts and stops
- Breath test results, including fails and warnings
- Aborted tests and the reason for the abort
- Power connects and disconnects (for tampering)
- Lockouts due to too many failed tests
Checks for signs of tampering
Tampering is rare, but the technician will check for signs of any attempt to interfere with or alter the device and wiring.
Checks battery and electrical system
The technician will ascertain the health of your vehicle’s electrical system so you are assured of uninterrupted operation.
This is a most important step. All breathalyzers (not just car breathalyzers) need to be calibrated periodically to ensure accurate results. Failure to calibrate is one of the reasons that commercially-available handheld and pocket breathalyzers tend not to be reliable). The technician will expose the device to a precisely-determined solution of alcohol and take a reading. If it is not within .005% the unit is adjusted or replaced.
All of the operations performed at your monitoring appointment are intended for one purpose: to ensure that you stay on the road, legally, safe and sober. That makes those 20 or so minutes time well spent.
