What is the primary purpose of the "Ohio Driver's Handbook"?

The primary purpose of the "Ohio Driver's Handbook" is to provide guidelines and rules for safe driving. This handbook serves as an essential resource for drivers to understand the laws of the road in Ohio, promoting safe driving practices and educating on the responsibilities that come with operating a vehicle. By including information on traffic signs, rules of the road, and safe driving techniques, the handbook ensures that drivers are informed about the standards they must adhere to in order to maintain safety for themselves and others.

While the other choices touch on aspects related to driving, they do not encapsulate the main focus of the handbook. It is not primarily a historical document, a vehicle maintenance guide, or a detailed account of penalties, although some of these topics might be mentioned in the context of providing a comprehensive understanding of safe driving.
