Regulatory sign
Speed Limit Sign
The maximum lawful speed on this stretch in ideal conditions. It is a ceiling, not a target.
What to do
Do not exceed the posted figure, and drive well below it when rain, fog, darkness, or traffic make that speed unsafe. Every state's basic speed law makes the conditions, not the sign, the real limit.

Regulatory signs state a law. Ignoring one is a traffic offence in its own right.
