In carparks and on private roads, vehicles are slowed down with the use of speed limit signs and speed ramps. The usage of various warning signs, such as ahead only signs, is necessary for safety. There are three different signs for different speed limits: a 5 mph sign, a 10 mph sign, and a 15 mph sign. The speed ramp, ahead only, and speed limit signs are composed of weather-resistant hard plastic and aluminium. What impact does a ramp's length have on speed? Speed ramps work to reduce accidents and calm traffic by employing humps to limit speed. On ramps, the distances between speed restriction signs should range from 25 to 150 metres. As the speed ramps get closer together, they reduce speed, which slows down traffic. When relevant, all of our Speed Ramps & Restrictions Signs are designed to meet UK government regulations or best practise. You will find all of our signs that limit traffic speed are compliant with ISO7010.
