I haven’t been able to confirm this anywhere. If this were not the case, when transcription occurred, if the transcription were based upon the incorrect side of the DNA molecule, a completely incorrect output would result. Complementary sides should be aliases of each other, but I have not been able to find anywhere whether this is the case.
Transcription is a highly regulated process, cells aren't just producing random RNAs from random stretches of DNA.
The transcription machinery needs to bind to DNA to get started, which requires a promotor sequence. It's not necessary for DNA to "read" the same way forwards and back, because it'll only be transcribed in the correct direction.
