I am trying to clarify a few points with Interstate vs. Intrastate regulations, specifically in Texas. The company I work for is based in Florida, but my home terminal is in Texas. The vehicles I dispatch are registered in Florida. 90% of our transport stays Intrastate inside Texas. My corporate office is suddenly telling me that our vehicles, even when operating Intrastate, are subject to Federal rules, rather than the rules adopted by Texas for Intrastate commerce. However, when I question them, they cannot intelligently point to a statute/rule/law that backs this up. Can anyone please help me with this? For the purposes of this question, I am only asking about Intrastate. I am aware that Interstate requires full FMCSA compliance.
