What are you (vehicle no. 3) required to do when approaching the following intersection (the red vehicle is not an emergency vehicle)?

1. You have right of way because you are crossing in a straight line (3).
2. Enter the intersection before the garbage truck (2), as it must yield (you [3] are coming from its right).
3. Give right of way to the tractor coming from the right only (1).
4. Correct answer: Give right of way to the crossing tractor (1) and truck (2).

WhyYou have a Give way sign, so you let everyone on the crossing road pass: both the tractor and the truck. Going straight gives you no priority here.
