Bumpers are an important part of a vehicle, as they protect the car from damage in the event of a collision. Chromed bumpers are bumpers that have been coated with chrome, giving them a shiny and attractive appearance. Senators are also referred to as bumper stickers, which are adhesive labels that can be placed on a car's bumper to express a political opinion or show support for a cause. Finally, stickers are also used to decorate bumpers, often featuring humorous or artistic designs.
