Firstly, note that vehicles B and D must give way to crossing traffic because of the yield signs. The sequence should be as follows:

Vehicle C goes first because it is turning right and there are no yield signs requiring it to yield to any of the other vehicles.

Moped A is on a priority road but is turning left, so it must wait for vehicle C to pass. It is advisable for moped A to enter the intersection to wait, allowing any vehicles behind it that are going straight to pass.

Vehicle B must yield to all other vehicles and needs to yield to Moped A, which is now in the intersection.

Vehicle D must also yield to all other vehicles. Vehicle D should wait until vehicle B has crossed the intersection, as vehicle B is on its right side. Vehicle D must also yield to all other vehicles. Vehicle D should wait until vehicle B has crossed the intersection, as vehicle B is on its right side.
