I guess either nobody works on the road or nobody wants to admit to it.
BTW, in many states and under federal law this is also true if the coach is used to carry, for example, sales samples, tools, or any other items that are used in business or trade (as opposed to items strictly for personal use). Even signs or the name of a business or professional music group on the coach can cause it to be adjudicated as commercial.Note that cash money does not have to change hands for a coach to be determined to be commercial and fall under all the requirements for commercial vehicles and drivers. For example, a coach owned and operated by a church to transport church members on outings, even with no money involved, is a commercial vehicle de facto. There have been several high-profile accidents in the last few years where churches who did not realize this were found to be in violation.Many states have exemptions written into their laws that allow passenger cars and sometimes even light trucks to be used for certain commercial purposes without them becoming commercial vehicles. However such exemptions almost never extend to heavy vehicles such as coach conversions and even off-the-shelf RVs. And it is certainly the case that there is no such exemption under federal law, which becomes operative as soon as the vehicle crosses a state line.FWIW.-Sean
