Advisory speed sign.
A yellow diamond-shaped sign with a black number inside indicates the highest safe speed limit in that area.
road conditions, traffic density, and how far you can see ahead
The highest speed i've known that is safe to do to a CPU is 4.0 GHz. And even then that required Overclocking.
maintaining enough room between you and the vessel ahead to be able to stop or avoid collision
as a defensive driver you must follow the car ahead of you at safe distance of?
Pretty safe, go ahead and use it.
On many highways it is unsafe to continue at the normal speed limit as you go around a curve (especially for large trucks with a high center of gravity that might tip over), therefor reduced speed signs (often yellow advisory signs not the usual white legal signs) are posted indicating reasonable and safe speeds to use through the curve.
If the posted speed is not safe at that time
Accidents
