About Shark's teeth: give way, not a stop requirement: which statement is WRONG?
Shark's teeth only apply if a sign B6 also stands next to them; without a sign the marking is not binding.
If shark's teeth and signs are absent, the main rule automatically applies: priority to drivers from the right.
Shark's teeth mean: give way, not a stop requirement.
B6 means 'give way', just like shark's teeth.
