Which of the following traffic signs allows parking in a position that is not parallel to the sidewalk?

- 815
- 819· Correct answer
- 512
- 513

The correct answer is 819 because: sign 819 marks parking spaces marked in white, and it permits parking according to the markings, including perpendicular or angled (non-parallel) parking. The other signs do not permit parking at all: 815 is traffic islands (parking on them is prohibited), and 512/513 are stopping places only, for picking up/dropping off passengers.
819 = parking according to ground markings (including perpendicular/angled)
Confusing road markings with parking signs, these are ground markings, not signs
