Light has a speed limit because it travels as electromagnetic waves, which are constrained by the properties of space and time. The limitation is influenced by the fundamental constants of nature, such as the speed of light in a vacuum and the permeability and permittivity of space. These factors combine to set the maximum speed at which light can travel, known as the speed of light in a vacuum, which is approximately 299,792 kilometers per second.
the posted speed limit
When another speed limit sign is reached that changes the limit from the previously posted one.
