As I’ve mentioned before, one of the things I’m going to have to do when I get my driver’s license back is have an ignition interlock device installed in my car. The interlock will force me to take a breathalyzer test before I can start the car and at random intervals while I’m driving, to ensure that I don’t drink and drive.
This is not only inconvenient and expensive (I’ll have to pay for installation and removal of the device and for monthly inspections), but it puts me at risk of going to jail for a false positive result. For example, an Australian man had to go to court because an ice cream treat caused him to blow a positive number on his interlock device.
The lesson, as always, is don’t get caught drinking and driving in the first place.
