It is important to make sure that the ball on your hitch is tight in order to prevent any accidents while you are driving. If the ball is not tight, it could come loose and cause the trailer to detach from the vehicle. This could lead to serious injuries or even death. It is best to check the tightness of the ball before each drive, and if you notice that it is starting to loosen, tighten it up with a wrench until it is snug.
