My Spouse Wants to Use My Car – With My Ignition Interlock

If you’ve just been ordered to have an ignition interlock installed in your vehicle, you probably have some questions. One of the most common is: will my wife (or husband) be able to use my car after the interlock is put in?

Anyone Can Use an Interlock-Equipped Vehicle

The answer is that anyone can use a vehicle on which an ignition interlock has been installed. You just need to make sure of two things:

1. The person using the vehicle needs to know how to operate it. That means the proper volume of breath and the right “hum” tone. Sometimes an interlock takes a bit of getting used to. At Monitech we’ll be happy to train anyone who uses your vehicle in the operation of the interlock device, at no charge.
2. More important, you are responsible for any failed tests that occur with the interlock. So if you lend the car to a friend who fails the test due to drinking, you could be hit with the violation.

Knowing this, it’s important to allow a vehicle with an ignition interlock installed to be used only by people you know, and whom you trust to drive while sober. The device records every test and every driving session, but according to most state laws, the one ordered to install the interlock is the one to whom violations will be counted against.

Apart from exercising some caution about whom you let use your vehicle, there’s not much to owning and driving an interlock-equipped car. The purpose of the device is not to restrict but to enable – it enables motorists who are alcohol-free to go about their lives and drive where they want, legally and safely.
