Practical examples: 1. How not to do it IMO: Road next to me had a limit of 60 because of "road works", there even was a road works sign standing there. Everyone knew it was safe to drive 80. One day I was driving suddenly after months of inactivity a worker comes walking out into the road while I come driving. The sun was low and I just saw his legs moving and managed to brake and steer away. If I had crashed it would have been my fault - and I would have deserved jail and losing my license. But I totally wouldn't say road authorities would have been without blame: Designing a 80 zone, then training everyone to think the road works sign is just a forgotten artifact is really really not a good idea if you intend to suddenly send your people out there in low light. 2. How it should be done IMO: Next to a school that I sometimes drive past there is a 60 zone. But it (used to) only apply when kids could be reasonably expected to be there (0600 - 2000 or something). Every summer road authorities would even cross it out. This way we are constantly reminded about why there is a very valid reason to slow down at this place - and we are reminded that at least some of them honestly think before they restrict us.
