Observation, Speed & SpaceStandalone practice
On an Iowa highway governed by the ordinary default in §321.285(3), no posted or other special speed restriction applies. What is that current default maximum?
Correct answer: 60 mph.
Why
Since July 1, 2026, the ordinary default in subsection 3 is 60 mph unless another restriction applies. Special road categories, district limits and posted limits can differ. Conditions may require a lower safe speed even where 60 is legally available.
