Portable Folding Speed Bump is the perfect choice when you need a temporary solution to slow traffic down. Folding portable speed bumps are constructed from durable, injection-molded, polyurethane plastic with black and yellow sections and reflective directional arrows for added visibility. These speed bumps are easy to deploy quickly. Built-in handles on each end enable them to be placed quickly, and then folded back up for compact storage. Each unit includes a storage bag. Temporary speed bumps are widely used for traffic control in emergency situations or for special events or school zones where traffic needs to be slowed.
