Can other people drive my vehicle if I have an ignition interlock device?

Intoxalock’s mission is to promote sober driving, no matter who is behind the wheel. One of the questions you might have when you install an ignition interlock device in your vehicle is whether or not anybody else will be allowed to drive your car for the duration of the time the interlock is installed. Some people who are required to install interlock devices share vehicles with spouses or teenage children and wonder if they will need to make alternate driving arrangements for those individuals.

Can somebody else drive my car with an ignition interlock device installed? Fortunately, any sober, responsible driver may operate a vehicle with an Intoxalock ignition interlock device installed. However, even if the additional driver has a clean driving record with no drunk driving convictions, he or she will still be required to submit breath samples before starting the car and at random points throughout the drive as required by each state’s regulations.

There is no way to disable the device for certain drivers, therefore, it’s important to make sure anybody operating your vehicle is properly trained on how to operate the ignition interlock device to avoid errors and improper usage.

If you have an ignition interlock device installed in your vehicle, it is advisable to be extremely careful with who you choose to hand your keys over to. We recommend that Intoxalock users diligently keep track of who has driven their car when, as the Intoxalock customer will be held responsible for all the information on the data log, regardless of who was driving.
