You are driving in fog on a small roundabout just outside Appingedam. At the entries there are no signs and no shark's teeth. You are already on the roundabout; from the right a cyclist wants to enter the roundabout. What do you do?
You go first: whoever is already on the roundabout goes before whoever wants to enter
You go first: a cyclist lets a car that is already moving pass first
The cyclist goes first: without a sign or shark's teeth, traffic from the right goes first
Explanation
False — you think traffic on the roundabout goes first in any case. That only holds when the entry has a give-way sign and shark's teeth. Without them, traffic from the right simply goes first, so the entering cyclist goes first (Book p.82, p.84).
