Does anyone know if it's a bylaw about the company trucks and trailers that are parked in the streets?

Company Business Trucks

I don't know if anything like that is in the bylaws.I think Laura in the model home would know that answer. I think though that if a person has to use thier truck for thier job, and that truck is required for them to do thier job, then the bylaws may not apply to that person and the company vehicle.Maybe they have to keep them in the driveway and not on the street(?) I'm not sure though, just guessing.

commercial vehicles

According the Association rules, no commercial vehicles are permitted to be parked in the street.

bylaw

There is nothing stating that cars cannot be parked on the street. Maybe when the HOA is put in place you can bring it up then.
