What to do if only the front wheels have passed during a yellow light?

[EvanAnn]

If you have already passed the stop line before the yellow light turns on (i.e., crossed the line during the green light and continued moving forward when the yellow light came on), there should be no issue. If the yellow light turns on while you have not yet passed the stop line and you proceed to cross the stop line during the yellow light, it will be treated as running a red light, usually resulting in a fine and a 6-point penalty.
