It is well known that positive values of redshift drift is a signature of dark energy within the conventionally studied Friedmann-Lema\^{\i}tre-Robertson-Walker (FLRW) universe models. Here we show — without making assumptions on the metric tensor of the Universe — that redshift drift is a promising direct probe of violation of the strong energy condition within the theory of general relativity.
