A Speed Bump is a traffic calming device that is used on roads, car parks, or anywhere that cars, motorcyclists and bikes travel. A speed bump slows the speed of a vehicle, improving safety not only for the drivers of vehicles but also for pedestrians. A speed bump can also encourage drivers not to exceed enforceable speed limits. Speed bumps can also be used to protect cables and wires that run across a traffic area. Most speed bumps are replaceable as needed but some are permanent fixtures that consist of concrete, asphalt and tarmac.
The yellow and yellow/black replaceable speed bumps are Hi-vis (high visibility). High visible speed bumps ensure that at night whether it is within a town or city they are seen. When driving on an unlit or dimly lit road, the lights of a vehicle display the speed bump with its reflective surface.
The speed bumps are normally pre-shaped but you can select a speed bump by size – height, width, depth (length).
Channels are designed underneath the speed bump to store cables and wires. The channels are built into the speed bump by the manufacturer and help in protecting the cables from traffic travelling over the speed bump. When buying a speed bump that requires cable channels, ensure that you match the cable size to the channel size.
