You should check with the road authority because they might be fake.
One day I was driving down a road that I'd driven down many times when I spotted a new speed limit. It was posted in a weird location and the speed was odd.
I contacted the local main roads department and learnt that they didn't know about these signs. The next day they were gone.
Agreed, having a minimum speed sign on a stroad is just begging for pedestrian deaths. It would be such an obvious liability that nobody in charge of transportation would allow it.
Every municipality has a minimum speed limit so you can’t just have someone driving 1km/h down the road creating a rolling blockade. Most are posted on the entrance into the municipality.
There are reasons for both sides to have and not have specific laws.
A relative of mine rear ended someone and couldn't understand why they were at fault for the accident. Just kept saying the person in front of them just stopped out of nowhere and there was nothing they could do.
People just don't realize they're supposed to give that much distance to the person in front of them. You're supposed to be able to stop without hitting the person in front of you if they, for any reason, stop without warning.
In my area the driving manual only discusses stopping/following distances for the commercial drivers license, not the standard drivers license
Based on the number of brake lights, either they're stopped, or about to be inside that prii's ass. Given the op didn't mention a crash, I'm going to guess traffic is stopped.
In Denmark we have a single piece of highway were we have a "crawl lane". It's slightly uphill and outside the lane you must go at least 80km/h. I know it is more common in Southern Europe.
Here in Germany, the Autobahn has a minimum speed cars need to be able to go (60 kph) although it’s not a minimum speed you necessarily need to drive.
However, we do have a dedicated minimum speed sign, but it’s very rare and usually only used in very specific places. The only one I know is a long and windy bridge on the side of a small mountain where, depending on your lane, you need to go at least 60, 80 or 90, I think.
That has to be a misprint or a photoshop. There is zero chance of a minimum 30 mph (or kph) inside city limits, especially with a perpendicular entrance/exit right there.
I've seen signs like that on the bridge from Virginia to Maryland. It makes sense though, it can be very dangerous with a large speed differential on that particular bridge. It's kind of a scary bridge. My ex-wife refused to drive on it.
I see your logic and had the same thought, but then wouldn't a "No stopping at anytime"/"No parking" sign accomplish the same thing? "No Loitering" sign as well. If the point is for the cop to be able to point to a sign, those already exist and are much more broad and easy to use(or misuse, depending on your perspective). Like others said, an absolute minimum speed limit seems destined to harm pedestrians. Plus, you can see it's before a stoplight. So not even logical.
