When an intersection is posted with both traffic signs and traffic lights, the instructions of which has the priority over the other?

1. Traffic signs always have priority (a traffic light might malfunction)
2. A stop sign has priority over a non-flickering traffic light
3. A “right-of-way giving” sign has priority over a non-flickering traffic light
4. Correct answer: Traffic light signals (except for a flashing yellow light) have priority over a right-of-way sign

WhyAt a junction with both lights and signs, the lights apply, except for a flashing yellow. The right-of-way signs take over only when the light flashes yellow or is off.
