Hacked into openstreetmaps? Not necessary, they publish helpful instructions right on their wiki on how to edit speed limits: https://wiki.openstreetmap.org/wiki/Speed_limits https://wiki.openstreetmap.org/wiki/Speed_limits I do know of one instance where modifying street signs tricked humans: there's a short speed-trap section of road outside a rural town north of me that's labeled 25 mph even though the approach roads are 45 mph. Apparently it's zoned residential even though there are only like 5 houses set way back from the road (looks like it should be 45, maybe 35). Seems like someone in the 70s thought that zoning something for higher density caused high-density housing developments to arrive. Of course, this section was where the cops liked to sit. When I was in high school, some kids pulled legitimate signs off a different section of road and re-labeled it 45 mph. While the average speed of traffic to school in the morning sped up dramatically for a couple weeks, the police did not agree that the presence of these signs changed the speed limit on the road. Fortunately, the perpetrators got off with a slap on the wrist, unfortunately, the county didn't review and revise the speed limits.

>the police did not agree that the presence of these signs changed the speed limit on the road Now this would be an interesting legal challenge. The official wording will vary by state but it'll be something like "a person must not, when the sign is in place on the highway, drive or operate a vehicle on a highway at a greater rate of speed than that indicated on the sign for that category of motor vehicle, unless another sign on a specific highway in the defined area so indicates" So... can you really be faulted if there's a not-obviously-fake speed limit sign? If I got a ticket for that I would definitely be disputing it.

  They literally unbolted the 25 mph signs and dumped them in the ditch... I think there was still a "speed limit reduced ahead" sign. You'd have a pretty easy case, I think, the only defenses would be "there's a sidewalk here so that's typically 25" and "you drove here before so you should remember it's 25".
