Parts of most trailer hitches are removable. The ball part of the hitch, the part that is used to fasten the cargo to the truck usually rests in the trailer hitch receiver opening. When the ball is removed, the receiver opening is left hollow. This opening protrudes from the tail of the truck and has sharp edges. People could bump into the metal rod or cut themselves on its sharp corners. 

It is a good idea to use a trailer hitch cover to protect the trailer hitch receiver opening. Trailer hitch covers can cover the opening and keep any debris from clogging it. Trailer hitch covers also protect people from cutting themselves or bumping into the hard edges. 

It can be inconvenient and time consuming to remove foreign objects from the hitch receiver opening. Dead, wet leaves, mud, sand, and other disgusting substances can clog the opening and make it difficult to secure the hitch to the truck. No debris can get into the opening if a cover blocks it. The trailer hitch cover fits into the receiver opening and covers the sharp and hard edges. Many trailer hitch covers are padded, so that people who bump into them do not get bruised. The covers are secured in the opening so that they do not fall out when the truck is in motion. 

There are a wide variety of trailer hitch covers available. They can have nearly any type of theme imaginable. Some have college logos, animal shapes, catchphrases, emblems, or cartoon characters on them. People can add their own personal touch to the appearance of their truck by choosing one of these unique covers.
