With your car you are approaching an intersection where there is a flashing yellow traffic light . You must yield to vehicles approaching from the cross road ? .
Yes, because I must exercise extreme caution and give way, if necessary, to both vehicles approaching from the right and from the left .
Yes, but only when there is a vertical sign next to the traffic light that forces me to give way .
Not because the traffic light tells me that I must exercise extreme caution and, if necessary, give way, only to vehicles approaching from the right .
