Yes, because it wouldn't be safer to have everybody going the same speed, you know.magicglock wrote:Not quite....the picture doesn't show the second sign very well. I believe the second sign has language at the top that only applies to Trucks or Commercial Vehicles. So daytime passenger vehicle limit is 80 while truck/commercial daytime limit is 70. Correct me if I am wrong.

That's also why I have a problem with day/night limits, since not everybody is going to think the changeover is at the exact same time. Don't even get me started on school zones posted by time, making everybody look at the clock instead of the road.
