Solid White Line
A solid white line marks the right edge of the roadway or separates lanes of traffic moving in the same direction. You may travel in the same direction on both sides of this line, but you should not cross the line
unless you must do so to avoid a hazard.
my bold added. At least you clearly may cross the line to go around the parked landscapers.
Lane markings are defined and regulated by Federal rules, the latest being 2009
Page 370 2009 Edition
28 Solid white lane line markings may be used to separate through traffic lanes from auxiliary lanes, such as an added uphill truck lane or a preferential lane (see Section 3D.02).
29 Wide solid lane line markings may be used for greater emphasis.
Standard: 30
Where crossing the lane line markings is prohibited, the lane line markings shall consist of a solid double white line (see Figure 3B-12). bold added
Also
see page 420 where there are drawings showing prohibited vs discouraged crossing markers.
Again, you may cross a solid single white line. Discouraged but not prohibited. I cannot find any rule specific to parking in the diamond lane.
Florida law
316.1945 has several parking prohibitions including:
9. On a bicycle path.
As the diamond lanes are also used as bicycle paths, this may or may not apply as they are not exclusively bicycle lanes. It also is not clear what the differentiation may be between a bicycle path and a bicycle lane.
If there is a general rule against parking on the main streets of the villages, I have never seen any posting of signage. Can you park on Morse? or Buena Vista? Parking is only prohibited
10. At any place where official traffic control devices prohibit stopping. [that means signs]
caveat... not a lawyer. When you get your ticket for parking on Morse, saying Blueash said it was okay will not work in court.
