Which of the following is true about speed limits in Ohio?

In Ohio, speed limits are indeed posted on signs and generally enforced by law enforcement. This means that drivers are expected to adhere to the specified limits indicated by road signs, which are strategically placed to inform motorists of the legal speed to maintain for safety and consistency on various types of roads.

The enforcement of these speed limits helps to regulate traffic flow and reduce accidents by providing clear guidelines for drivers. Speed limits can vary based on the type of roadway, the surrounding environment, and specific circumstances, which is why it is essential for drivers to observe and follow the posted limits.

In contrast, while other statements may suggest various aspects about speed limits, they contain inaccuracies. For example, not all roads have a maximum speed of 65 mph; the speed limit can be lower in residential areas or higher on highways. Similarly, a 50 mph speed limit is not typical in residential areas, where limits are usually set lower to ensure the safety of pedestrians and local residents. Lastly, speed limits are not optional; they are laws that must be followed by all drivers to maintain road safety.
