Dean,
I am no expert, but since you made the mistake of asking, here is my interpretation.
44011(a) HS Begins by saying that ALL internal combustion powered vehicles have to be smogged. As with most rules, there are bound to be exceptions. IOW, cases where the vehicle does not have to be smogged. That is what they are introducing when they say, "except for all of the following".
The code then lists some of the cases where a vehicle would not have to be smogged. Where the vehicles are "excepted" from being smogged.
Then, and you gotta love the people who write these things, they list cases where vehicles are "excepted" from the exception. They didn't have to be smogged, but now they do if they are in one of the categories listed. ie: Specially Constructed Vehicles
The part I don't like is, "as determined by the department". There is a world of grey there.
The thing of it is, this language is already the law and is not going to be changed by AB 2683.
AB 2683 only removes the thirty year exception to being smogged, and replaces it with any vehicle older than '76 is excepted.
Under the current law you can look forward to not having to smog your car once it is over thirty years old. If AB 2683 passes, any car from model year '76 on will have to be smogged regardless of how old it is.
I hope that was a bit clearer than mud
