Don't even sit in the car if you are over the limit, some states are now convicting people based on an assumed intention to drive - even if you are passed out and the keys are in your pocket when the occifer finds you, or even if the car won't start!

this is a toy, don't use it to see if you can drive, it's not accurate at all. You could die or kill someone if you use this as your test to see if you should drive.

Yeah. Call a taxi. It's cheaper than jail.

I hate these things. They're never used for safety, they're used to try to get the highest score.
