15 minutes of actual research, including an entire video on CalFire’s Instagram page, DISPROVES THIS.
NO incoming rigs are being stopped for emissions testing.
What I’ve been able to find out is that, as is normal, these vehicles coming from hundreds of miles away, are given a pre-deployment inspection. They’re enormous, heavy vehicles and are checked to make sure they are in top working order. Often, from the journey, the need to have parts replaced. This is done to ensure the safety of the rig, crew, and to make sure the vehicle isn’t creating any sparks. CalFire has a whole video on it over on Instagram.
But, no, they are NOT being stopped for emissions testing. THIS. IS. A. LIE. Stop spreading it.
