What is the primary function of a trailer jack?

To enhance speed while towing
To support and stabilize the front when not attached
To increase towing capacity
To assist in braking efficiency

The correct answer is: To support and stabilize the front when not attached

The primary function of a trailer jack is indeed to support and stabilize the front of the trailer when it is not attached to a towing vehicle. This stabilization prevents the trailer from tipping over and ensures it remains in an upright position. A trailer jack allows for easy hitching and unhitching as it can be adjusted up or down to fit the height of the towing vehicle's hitch. When the trailer is parked, the jack provides the necessary support to keep it steady, which is essential for safety, especially when loading or unloading. The other options highlight functions or benefits that are not related to the primary role of a trailer jack. Enhancing speed while towing, increasing towing capacity, and assisting in braking efficiency pertain to different aspects of towing dynamics rather than the specific purpose of the jack itself.
