Why do they announce where the check points are going to be?

I used to wonder the same thing years ago, but since I barely drink, I no longer question it and just add it to one small thing I can count my blessings over. I can avoid the area and any bullshit. I've been caught up in a few of these, and they have absolutely nothing to do with drunk driving, but rather trying to give out 'revenue enhancers' (tickets) or make arrests for whatever reason they can.

I believe it's just part of their requirements that, as far as I understand it, make it easier for the case to hold up in court (against claims of "entrapment" and the like).

Troopers have told me they have to allow you an alternate street to turn down before you reach the checkpoint -- a way out, if you choose to take it.

That said, they can choose to follow you in case/until you break a traffic law, then pull you over.

According to the news article, one person was cited for having an open container of alcohol at the Northwood checkpoint.

From what I saw on the news, it looks pretty obvious that you're approaching a checkpoint of some sort - big huge lights, lots of police vehicles, etc.

Why in the world would you pass through a DUI checkpoint with an open container of alcohol?

(Presuming that Barrett Andrews comment above is true about the alternate street available.)

The reason for publication is a legal compromise. The 'safety checkpoint' is a violation of the fourth amendment of the US Constitution. Ohio legislators know this and don't give a damn. They want control. The USSC ruled in favor of the legislators (big surprise there, right?) but stipulated that the mere civilians must be forewarned, so now we have checkpoints and publication of the checkpoint location. Because it's for the children, and for our own safety.

OK, while we are on the subject...

On Memorial Day weekend they had check points for seat belts. I am sorry, but if the State has budget issues, why pay overtime for this????

I drive a 1990 red Mazda Miata with a winter hardtop. I'm 5'1" tall. The seat is black. The seat belt is black. My winter coat is black. The seat belt comes from below and behind my left shoulder. Get the picture? Next winter I'll probably get pulled over left and right. I always buckle up, but there's no way of telling so from just observing through the window. Maybe I'll spray paint the sealt belt a flourescent color.

The open container could be a simple as an old beer can from weeks ago, if they can get so much as a drop out of it its considered and open container. Probably get away with it even if its dry. Why i dont care even the passengers aint gonna drink in my vehicle.
