What is the maximum speed limit on most highways in Ohio?

The maximum speed limit on most highways in Ohio is 65 mph, unless otherwise posted. This speed limit applies to interstate highways and some other major arterial roads where the design of the road allows for higher speeds while still maintaining safety for all travelers. It's important to always be vigilant for posted signs as speed limits can vary by specific location, especially in construction zones or areas with higher pedestrian activity.

Opting for the 65 mph limit reflects a balance between efficient travel and safety. Higher speeds, such as those indicated in other options, are not generally permissible on regular highways in Ohio to promote safer driving conditions, considering factors like traffic density and road characteristics.
