CBD is to THC as Sharps or Odoules, (I know I butchered those names, I don't drink) is to actual bear. CBD is no more relaxing than chamomile tea, or the smell of lavender.
Full spectrum, esp. that with terpenes, such as the chemical compounds responsible for the smell of lavender (which is in most blue strains, btw) would have various effects based on what's known as the profile. Linalool, lavender terp, is relaxing, as is mycerine. Other terps are stimulating, such as linoline.
I seriously doubt full spectrum CBD would have any effects to be worried about while operating heavy machinery. Of course, I'm not a doctor, nor play one on TV. The prudent advise, is, before operating any heavy machinery, learn how YOU are affected, by anything that you may have a concern about. Be it cold medicine, antihistamines, that sleepy time tea that has valarian root you got at a health good store, or anything else that may be, relaxing... Couch lock, munchies, or other such issues? I doubt CBD is capable of such ...... madness.
