What objectives do speed limits set by the traffic authority serve?

Correct answer

Promote safety and appropriate traffic flow.

They promote safety and traffic flow appropriate to the road and conditions. They do not guarantee that accidents never occur or permit sacrificing safety for greater flow. A maximum limit is a ceiling, not a speed always to maintain: reduce speed for visibility, grip, traffic and other circumstances. Minimum-speed rules do not require unsafe speed where justified reasons apply.
