RUBBER SPEED HUMPS – PERFECT FOR GATED COMMUNITIES, DRIVEWAYS, PRIVATE ROADS. Speed humps are wider and more heavyset than bumps. These create gradual deceleration, and are generally placed in areas where low speeds are already encouraged. Similar to speed tables and cushions, humps are powerful and effective traffic calming measures. Humps are often placed outside in gated communities, driveways, and school zones. Speed humps are sold by the foot.
