In Ohio, what should a driver do before changing lanes?

Answer: A — Check mirrors and signal

To safely change lanes, a driver in Ohio should check their mirrors and signal. This ensures that they are aware of their surroundings and that other drivers are informed of their intention to change lanes. Checking mirrors allows the driver to see the vehicles around them, ensuring that it's safe to make the maneuver. Signaling is a critical aspect of driving that communicates to others on the road what the driver plans to do, thereby reducing the risk of accidents. Focusing only on blind spots neglects the important information gathered from mirrors, and signaling without checking mirrors may lead to unsafe lane changes, as it doesn't ensure that the way is clear. Changing lanes whenever possible is unsafe because it disregards the necessary precautions drivers should take to ensure their safety and the safety of others on the road. Thus, the proper practice is to always check mirrors and signal before changing lanes.
