Bumpers, also known as fenders or guards, are protective components placed around the perimeter of a vehicle. They are designed to absorb impact and prevent damage in the event of a collision. Synonyms for the word bumpers include buffers, cushions, barricades, shields, bump guards, and protective barriers. Bumpers can also be referred to as bull bars or brush guards, specifically used on off-road vehicles to protect against brush and wildlife. Additionally, in sports such as bowling, bumper lanes are used to prevent balls from going into the gutters, and in pool, bumper sticks are used to help prevent scratches on the cue ball.
