speed-humps02Speed humps and bumps are traffic calming devices that use vertical deflection to slow motor-vehicles and improve safety conditions.

A speed bump is smaller and shorter than a speed hump and generally require vehicles to reduce speeds to 5 mph or less. Speed bumps are great for areas with high pedestrian traffic and already decreased speed limits such as parking lots.

Speed humps are wider and smoother to drive over than speed bumps. The purpose of this is to allow the entire vehicle to be on the hump at once before descending. This will reduce the chance of a vehicle bottoming out. They are generally used in a street to calm traffic while reducing the chances of vehicular damage
