Bumper stickers are adhesive labels designed to be displayed on the rear bumper of vehicles. They often feature catchy phrases, slogans, or images that convey messages about personal beliefs, humor, or support for causes. Common themes include politics, environmental issues, and social movements, making them a popular form of self-expression. These stickers are typically made from durable vinyl to withstand weather conditions and are easy to apply and remove. Many people use bumper stickers to promote businesses, share personal interests, or show support for sports teams or charities. Their visibility on the road allows for broad communication with other drivers.
