Speed bumps are traffic calming devices that use vertical deflection to slow motor-vehicle traffic and improve safety conditions. They are commonly used to enforce low speed limits under 25mph or lower.

These devices can be made from various materials like asphalt, concrete, recycled plastic, metal, or vulcanized rubber. Asphalt or concrete are traditionally used due to their durability and effectiveness in slowing traffic. However, they can be difficult to shape and form. Rubber products are pre-shaped to standard sizes and are typically bolted down, making them easier to install or remove. Temporary bolt-down installations are ideal for testing speed bumps before implementing larger projects and during winter snow periods.
