Observation, Speed & SpaceStandalone practice
On a four-or-more-lane interstate highway posted 70 mph, conditions allow normal safe travel. What minimum speed applies unless a lawful or safety reason requires slower travel?
Correct answer: 50 mph.
Why
Florida’s highest permitted posted limit on limited-access highways is 70 mph; many roads are posted lower. On qualifying interstate-system highways with at least four lanes, the minimum is 40 mph, increased to 50 mph when the posted maximum is 70 mph. Slow as necessary for safety, traffic or legal requirements. Keep right when traveling slower than normal traffic, subject to passing and turning exceptions.
