At a junction in Deventer there are white triangles on the road in front of you with their points towards you (shark's teeth). There is no traffic sign with them. What applies to you here?
You give way to traffic on the crossing road, even without a sign
You must first come to a full stop here, just as at a stop sign
Without a sign they do not count; then traffic from the right simply goes first
Explanation
False — you read shark's teeth as a duty to stop. Shark's teeth mean the same as the triangle pointing downwards: give way to traffic on the crossing road; you only stop if that is needed to give way. A duty to stop belongs to the octagonal stop sign, not to shark's teeth. Book p.238.
