What are the trailer hitch classes defined by the Society of Automotive Engineers?

The correct answer identifies the trailer hitch classes defined by the Society of Automotive Engineers (SAE) as Classes I-IV. This classification system categorizes hitches based on their weight capacity and design specifications, helping consumers select the appropriate hitch for their towing needs.

Class I hitches can typically handle up to 2,000 pounds of gross trailer weight (GTW) and are suited for smaller vehicles. Class II hitches extend the capacity to around 3,500 pounds GTW, making them more versatile for a wider range of light-duty towing tasks. Class III hitches can handle loads of up to 8,000 pounds GTW, providing substantial strength for medium-sized trailers. Lastly, Class IV hitches are designed for heavier towing applications, supporting GTWs over 10,000 pounds.

This classification system is critical for ensuring that consumers select the right trailer hitch that meets their specific towing requirements and is compatible with their vehicle's capabilities. The specifications for Classes I through IV reflect the range of typical applications for light to medium-duty towing tasks, emphasizing the importance of selecting an appropriate class for safety and effectiveness in towing.
