Abstract
In this lecture I shall discuss the observational evidence relevant to the speeds of jets in radio galaxies and quasars. My conclusion is that the outer jets of weak (FR I) sources have non-relativistic speeds, while jets in strong (FR II) sources have speeds comparable with the speed of light, and perhaps very close to the speed of light.
