Get to know about black and yellow speed bumps!

Black and yellow speed bumps are the most popular speed reducers installed on roads at different sites for speed control. And they are the most popular speed bump colours.

They are one of the traffic control devices like stop signs, cones, and speed cushions. A sleeping policeman is another name for a speed bump in the United Kingdom.

Speed bump and speed hump are different from each other. A speed bump is a bump on the road with a height typically ranging between 76 and 102 millimetres (3 and 4 in).

There are many different types of speed bumps, and they come in various sizes, but to allow for drainage, space is usually left between the bump and either border of an enclosed road (i.e., with curbs and gutters).

Where to install these speed bumps?

Speed bumps act as speed breakers to control and manage vehicles’ speed and road safety effectively. So, any site where traffic flow and vehicle speed must be continuously managed should have speed bumps placed.

Public parking lots require controlled low speeds to avoid collisions between automobiles and people.

To keep employees and visitors to the site safe, industrial workplaces must verify that vehicles such as forklifts, vans, and buses operate at allowed speeds. In low-traffic areas, products such as traffic calming bumps may be used as an alternative warning for cars to slow down.

Speed bumps are effective in any area where the control of traffic management is necessary.

      These materials have higher permanency and are more effective at reducing traffic volume because of their rigidity and endurance. However, shaping and forming them into regular forms and precise dimensions can be difficult.

      To fulfil industry requirements, rubber items are already shaped to prescribed sizes.

      Preformed rubber goods are usually bolted down to make installation and removal easier. Temporary bolt-down installations are great for planners who want to evaluate the use and placement of speed bumps before putting them in place on a larger project.
