Speed Bumps

A speed bump (usually made from recycled plastics) is a velocity-reducing feature on roads that are designed to slow speeding vehicles or reduce through traffic as they drive through certain areas of a town or city. They are otherwise referred to as “speed hump”, “road hump” or “sleeping policeman” in British English while in places like in New Zealand they are sometimes referred to as a judder bar. Basically, the main function of a speed bump is to reduce or eliminate road accidents in places known for their trooping pedestrians; by forcing drivers to reduce their speed. Typically, bumps in a roadway usually have heights ranging between 3 and 4 inches (76.2 to 101.6). On the other hand, the lengths of speed bumps are typically less than but closer to 1 foot. The number of speed bumps on any particular road can be of any number depending on the length of the road and how busy it gets.
