From what I've seen things here in Utah are pretty fair. The signs are usually well in advance of the actual change. It's one of the things I like about where I live.

I think items like that needed to be address. Looks like a few states have. Fair is fair right. Unless you are kranz. :haha::O:

Yes, but that doesn't apply, it isn't a small town dept setting its limits to catch the unwary visitor.
Its the national set limit on a road near his home.

I got two cases in my local area. Both times I got puled over for speeding.

First time was when they reduced the speed limit from 70 km/h to 50 km/h on the main road trough a nearby town. And they reduced by removing the 70 sign and that's it. 50 is the urban limit if there's no sign.
The cops were raking in money. Even I fell into it. Managed to talk my way into a lower fine.
That's a stretch of road that's a kilometer long and straight with industry on both sides. Not a particulary dangerous section, but highly profitable one the first few weeks.

Then there's the entrance to the same town. I was leaving the town when I got caught. Managed to talk my way out of it. The thing is that it has some houses right at the side and has a blind corner the size of Russia.
At least 3 people are killed at that section every year. That's police protection of the area.

Speed limits in the United States are set by each state or territory. Speed limits vary primarily due to state laws, but also due to the type of road, land use, and more. (Wiki)

Municipalities cannot post their own speeds. However, placing the signs were they like is probably a different story.

I'm not going to read this whole thread. The OP has been brigged. It's ok to vent, andI will be the first to agree that many police are not professional. But you have expressed yourself poorly. Too much hateful rhetoric, too many derogatory terms aimed at people here, and no regard for members of the forum who may have been law enforcement officers.
