Here (IL), you can decline the breathalyzer (ASD), but it's automatic 90 day license suspension if you do. I think most states are similar. In IL, they made it a DUI / DWI eligible offense to just be *parked in your car* intoxicated (say, if you were at a bar, and decided to 'sleep it off' for a bit before heading out). I actually experienced this firsthand (many years ago, before the law was passed; not since)
I had a friend I used to work with who was a 3-time offender (no fatalities / injuries to others), and lost his license for 5 years - no work / hardship allowances.) He definitely fit the stereotype of an Irishman liking to get his drink on after work.)
When he got it back (wasn't automatic - had to go to court again), he had to have a breathalyzer with interlock installed into his Impreza - blow into it at .00 or the car doesn't start (I wouldn't be surprised if it recorded the event, too, but I never asked him about it). That lasted for a year or so; finally, he was able to get rid of it (and he got a different car, too - can't say I blamed him for doing that, since he was originally caught in the Impreza and had to look at it in his garage every day of those 5 years.)
No, I don't condone DWI (and if anyone on this site has lost someone to a drunk driver, I apologize if I sound like I do). But it is shockingly easy to blow .08 And I think they would go lower, if they could (we have the 'buzzed driving is drunk driving' PSAs, etc.)
Thankfully, Uber, Lyft and the like exist now (for the stubborn ones like me, who wouldn't think of imposing on a friend twice to drive them (night of / day after).
No, I don't DWI - but I'm not going to lie and say that I'd always have blown < .08, had I ever needed to.
As an aside - I know cannabis is legal nationwide now, in CA (or was supposed to be, in July - I remember hearing about last-minute scrambles on CBC Radio, when I was in Montana).
Any changes to the 'motor law', respective to it?
We'll probably be nationwide at the next party change at the presidential level, so I'm curious to see what might be coming. Probably 'zero tolerance' for us, I would imagine. Maybe an exemption for medical purposes (while driving), but that's a big 'maybe' (For you 'states rights' people out there - it'll be an unofficial federal standard, just as .08 is now - or your state will suddenly be funding its highway infrastructure on its own)
