Suppose the three vehicles in the picture all reach the intersection at the same moment. In what order should they go?
Correct answer: Yellow car, blue car, then the truck.
Answer options
ATruck, blue car, then the yellow car
BBlue car, yellow car, then the truck
CYellow car, blue car, then the truck Correct
Why
When vehicles arrive together, each driver yields to the vehicle on the right, so the blue car lets the yellow car, which approaches from its right, go first. The truck is turning left, so it must wait for the oncoming yellow car and for the blue car on its right, which leaves it last.
