All speed restriction signs in place on January 1, 1960, are hereby ratified and confirmed and shall establish the applicable prima facie speed limit unless and until changed pursuant to engineering and traffic surveys provided for by this code.
The legislature occasionally skips outline levels.
For example:
(3) A person may apply [...]
(4)(a) A person petitioning for relief [...]
In this example, (3), (4),
and (4)(a) are all outline levels, but
(4) was
omitted by its authors. It's only implied. This presents an
interesting challenge when laying out the text. We've
decided to display a blank section with this note, in order
to aide readability.
