You probably won't get much help finding the information.  After the supply chain issues arose from COVID-19, many states have been issuing permits for overweight and oversize loads for the transport of critical supplies.  The term Blanket Permit has been used for generations to describe permanent and semi-permanent exemptions and waivers for restrictions.  But it seems that we now have an urgent issue that if the authority (in this case, Florida DOT) issues a Blanket Permit (in this case, overwidth) that the drivers seldom check the truckers maps to actually verify that the route is capable of facilitating the oversize load.

Some restrictions are safety restrictions, some are maintenance restrictions.  If the route has a narrow bridge, a low overhead obstruction or a reduced weight/axle load restriction for a bridge structure, so-called Blanket Permits are never allowed.  In some cases, a Specific Permit can be granted.  Let's say that the only way to relocate an overweight thingy is to cross a bridge with a weight restriction.  The local jurisdiction may allow a proposal for a trucker to haul an overweight load with special trailers reducing the axle loads as much as practicable (which might still cause quite an argument before the permit is granted).  I'm also aware of haulers with special equipment that specialize in sneaking under low clearance restrictions (sometimes by selecting a lane with a slightly higher clearance, with special trailers that can drop a few inches at low speeds, or by dropping the load onto special dollies and pushing them under with tractors). 

For the record, I've never heard of any Special Permits being granted for overwidth loads when there is a physical width restriction.  If it won't go through, go around.

They also had that sign for points south of Krome, Card Sound, and Overseas Highway.





Sorry, Linus.

I could be wrong, but I suspect the bolded phrase is as sufficient an answer as the OP was looking for, hence the sarcastic comments upthread. My interpretation is that this particular sign is essentially a roundabout way of saying "No Vehicles Over 11 ft Wide on Krome Ave".
