What is the primary purpose of a trailer hitch?

The primary purpose of a trailer hitch is to connect a trailer to a vehicle. This connection is essential for towing, as it provides a secure link between the vehicle and the trailer, allowing for safe transportation of goods, campers, boats, or other trailers behind the vehicle. The hitch ensures that the load is balanced and distributed properly, which contributes to safer driving conditions.

While other options mention aspects related to vehicle performance, such as fuel efficiency, traction, or stability, they do not accurately represent the core function of a trailer hitch. A trailer hitch is designed specifically for the purpose of facilitating towing, making it a critical component for anyone who needs to transport trailers.
